It means are provided by which the storage chamber is independent from the filling state always completely with the medium filled, e.g. in that the volume of the storage chamber is reduced proportionally to the emptying.

Ein Austragstutzen kann in Axialansicht in einer oder zwei rechtwinklig zueinander liegenden Axialebenen gegenüber einer Stirnwand zurückversetzt sein, so daß diese beiderseits Finger-Druckflächen zur axialen Betätigung und Verkürzung der Austragvorrichtung bildet. Der Spender kann eine oder mehr Verdrängerpumpen, wie Schubkolbenpumpen, aufweisen. In deren zu verengenden Druck- bzw. Pumpraum kann beim Rückhub-Medium eingesaugt werden. Der eine Druckraum der simultan manuell zu betätigenden Pumpen kann ein Zerstäubungs-Gas und der andere Pumpenraum im wesentlichen gleichzeitig das nicht gasförmige Medium fördern, um so z.B. ein hochviskoses Medium zerstäubt auszutragen. Die beiden Verschlüsse können gegeneinander zeitverzögert öffnen und/oder schließen. Der Druck- bzw. Pumpenraum kann auch das gesamte gespeicherte Medienvolumen der Austragvorrichtung enthalten und statt mit einem dem Kolben gegenüberliegenden Einlaßventil mit einem Permanentverschluß als Boden der Druckkammer versehen sein. A discharge nozzle can be viewed in axial view in one or two axial planes at right angles to one another Front wall must be set back, so that these finger pressure surfaces on both sides for axial actuation and shortening the Discharge device forms. The donor can have one or more Have positive displacement pumps, such as thrust piston pumps. In their The pressure or pump space to be narrowed can be achieved with the return stroke medium be sucked in. The one pressure room that simultaneously manually actuating pumps can be one atomizing gas and the other Pump room essentially non-gaseous at the same time Promote medium, e.g. atomizes a highly viscous medium to carry out. The two closures can be against each other open and / or close with a time delay. The printing or Pump room can also store the total volume of media stored the discharge device included and instead of with a Piston opposite inlet valve with a permanent closure be provided as the bottom of the pressure chamber.

Der Kanal 38 mündet unmittelbar in den Auslaßkanal 28. Der Kanal 38 bildet einen gegenüber dem Kanal 28 im Durchflußquerschnitt wesentlich erweiterten Druckraum. Wird das Medium aus der Kammer 11 in diesen Druckraum 38 gepreßt, so wirkt der Abschnitt 37 als Kolben, welcher mit dem Schaft 26 gegen seine Federkraft gegen den Boden 35 bewegt und mit dieser Federkraft wieder zur Schließlage zurückgeführt wird. Der Auslaßkanal 28 bzw. 29 ist durchgehend ein Kapillarkanal, gegenüber welchem die Durchflußquerschnitte des Kanales 38, 39 vielfach erweitert sind. Bei seiner Verengung wird in dem Trockenraum 32 der Gasdruck erhöht, wodurch ebenfalls die rückstellende Federkraft bewirkt sowie justiert werden kann. Die Öffnungsbewegung der Teile 26, 37 ist der Strömungsrichtung 40 in den Kanälen 28, 29 bzw. den Öffnungen 8, 27 entgegengesetzt.Between the housings 30, 31 is an outgoing from the bottom 35 Connection channel 38 of the outlet channel 28 limited. This Channel 38 starts from connection openings 39, which the Bottom 35 between the shells 33, 34 about the axis 9 of the housing Enforce 30, 31. Channel 38 opens directly into the outlet channel 28. The channel 38 forms one opposite Channel 28 significantly expanded in the flow cross section Pressure room. The medium from the chamber 11 in this pressure chamber 38 pressed, the section 37 acts as a piston, which with the shaft 26 against its spring force against the ground 35 moves and with this spring force back to the closed position is returned. The outlet channel 28 and 29 is continuous a capillary channel, against which the flow cross-sections of the channel 38, 39 are expanded many times. At its narrowing becomes the gas pressure in the drying room 32 increased, which also causes the restoring spring force as well as can be adjusted. The opening movement of the Parts 26, 37 is the flow direction 40 in the channels 28, 29 or the openings 8, 27 opposite.

Der Tragkörper 5, 20 kann vor dem Aufsetzen des Deckels 4 an diesem oder am Behälter 3 festsitzend montiert und der Deckel 4 dann auf den Behälter 3 aufgesetzt werden, nachdem zuvor die Kammer 12 mit dem Hals 19 durch den Stutzen 17 hindurch eingesetzt worden ist. Die vormontierte Einheit aus den Gehäusen 30, 31 und dem Schaft 26 kann vor oder nach Montage des Tragkörpers 20 am Deckel 4 befestigt werden. Zweckmäßig wird zuerst die Kammer 12 eingesetzt, danach ggf. der Träger 5 und dann der Deckel 4.The cover 4 has an outermost end wall 41 and from this only to the chamber 11 above a jacket 42. that spills over a narrowed end portion of the container 3 approximately to to the end wall 15 outside, so that the connecting pieces 16, 17, 19, 21, 22, the plate 20 and the housing 30, 31 lie completely. The outside of the plate 20 is against the inside the wall 41 is stretched and forms a composite panel with it 20, 41. The support body 5, 20 can be placed on the Lid 4 firmly attached to this or to the container 3 and the lid 4 are then placed on the container 3, after the chamber 12 with the neck 19 through the neck 17 has been used. The pre-assembled unit from the housings 30, 31 and the shaft 26 can before or after Assembly of the support body 20 to be attached to the lid 4. The chamber 12 is expediently inserted first, then if necessary the carrier 5 and then the lid 4.

Die Kammer 12 ist mit der Außenatmosphäre über ein Einlaß-Ventil 43 leitungsverbunden, das an der Innenseite der Wand 41 innerhalb des Gliedes 22 liegt. Die Wand 41 weist eine Einlaßöffnung 44 auf, die mit einem druckabhängig bewegbaren Ventilkörper 45 verschließbar sowie zu öffnen ist. Der klappenartige Ventilkörper 45 ist einteilig mit dem Tragkörper 5, 20 ausgebildet und zur Öffnung gegen Federkraft gelenkig bewegbar. Der Ventilkörper 45 liegt in der Ebene der Platte 20. Die Kammer 12 ist von einer Blase oder einem Beutel 46 aus einer hochflexiblen, faltbaren und mikrodünnen Folie begrenzt, die ohne Beschädigung auf ihr Materialvolumen in dem Hals 19 zusammengeknüllt und dadurch in den Behälter 3 leicht eingesetzt werden kann. Der Hals 19 weist gegenüber der Folie wesentlich größere Wandungsdicke auf und kann einteilig mit dem Beutel 46 ausgebildet sein. Vom Stutzen 22 zweigt benachbart zum Ventil 43 ein Verbindungskanal 47 zum Einlaßende des Kanales 29 ab. Der Kanal 47 ist im Querschnitt von den Teilen 20, 41 begrenzt. Auch dieser Kanal 47 ist im Durchlaßquerschnitt vielfach weiter als der Kanal 29.The chamber 12 is connected to the outside atmosphere through an inlet valve 43 wired, the one on the inside of the wall 41 lies within the link 22. The wall 41 has one Inlet opening 44, which can be moved with a pressure-dependent Valve body 45 can be closed and opened. The flap-like Valve body 45 is in one piece with the supporting body 5, 20 formed and articulated to open against spring force. The valve body 45 lies in the plane of the plate 20. Chamber 12 is from a bladder or pouch 46 limited to a highly flexible, foldable and micro-thin film, which without damage to their material volume in the Neck 19 crumpled up and thereby easily into container 3 can be used. The neck 19 faces the film much larger wall thickness and can be made in one piece the bag 46 may be formed. From the nozzle 22 branches adjacent to the valve 43 a connecting channel 47 to the inlet end of the Channel 29 from. The channel 47 is in cross section of the parts 20, 41 limited. This channel 47 is also in the passage cross section many times further than channel 29.

Das freie Ende des Schaftes 26 bildet als Ventilkörper 50 ein konisch zugespitztes Verschlußglied. Es liegt in Schließlage an dem die Öffnung 27 bildenden Ventilsitz 51. Wird der Behälter 3 ohne Verformung des Deckels 4 zusammengedrückt und die Kammer 11, 12 unter Druck gesetzt, wird das Ventil 43 in seiner Schließlage gesichert. Aus der Kammer 12 strömt das Medium nacheinander durch die Anordnung 19, 22, 47, 29 zum inneren, vom Verschlußglied 50 nicht verschlossenen Ende des Düsenkanales 8 und durch diese entlang des Außenumfanges des Verschlußgliedes 50 nach außen, da das Verschlußglied 50 über einen Teil der Kanallänge in diesen Düsenkanal mit seiner Spitze hineinragt. Gleichzeitig strömt das Medium aus der Kammer 11 durch die Öffnung 39 in den Druckraum 38, welcher durch das Ventil 10 noch verschlossen ist. Der Druck bewirkt die Öffnungsbewegung des Körpers 50. Das Medium kann aus dem Druckraum 38 durch den Kanal 28 in die Öffnung 27 strömen, sich mit der dort bereits strömenden Luft vermischen und dann aus der Düse 8 austreten. In der Öffnungsstellung bildet der Körper 50 mit dem Ventilsitz 51 eine ringförmige Düsenöffnung 27. Deren größte Weite ist höchstens so groß wie die der Öffnung 8.The free end of the shaft 26 forms a valve body 50 tapered closure member. It is in the closed position on the valve seat 51 forming the opening 27.

Der Kopf 6 und/oder der Einlaß 44 können mit einem abnehmbaren Schutzkörper bzw. kappenförmigen Deckel 55 nach außen abgedeckt sein. Dieser weist eine eng an den Stutzen 6 angepaßte Deckhülse 56 auf, welche die Öffnung 8 verschließt. Im Bereich ihres freien Endes rastet sie über eine federnde Schnappverbindung in den Stutzen 6 axial gesichert ein. Gesondert von dem Schließkörper 56 und im Abstand davon steht von der Innenseite derselben Deckelwand ein weiterer Schließkörper 57 für den Einlaß 44 frei vor, welche in die Öffnung 44 eingreift. Die Nadel 57 kann das Ventil 43 zum Druckausgleich der Kammern 11, 12 geringfügig geöffnet halten.The head 6 and / or inlet 44 may be removable Protective body or cap-shaped cover 55 to the outside be covered. This has a closely matched to the nozzle 6 Cover sleeve 56, which closes the opening 8. in the The area of its free end snaps over a resilient Snap connection in the socket 6 axially secured. Separately from the closing body 56 and at a distance therefrom another closing body from the inside of the same cover wall 57 free for the inlet 44, which in the opening 44 engages. The needle 57 can the valve 43 for pressure compensation keep the chambers 11, 12 slightly open.

Nach Fig. 7 steuert der Kernteil 25 den Medienfluß an der Öffnung 8. Die Hülse 25 besteht aus einem gegenüber den übrigen Werkstoffen weicher federnden Werkstoff. Unter dem Mediendruck führt sie mit dem Sitz 51 gegenüber dem Grundkörper 2, 4 bzw. dem Glied 50 in Richtung 40 eine Öffnungsbewegung zur Öffnung des Verschlusses 10 aus. Dies kann nur durch eine rückfedernde Längenstreckung des Kernes 25 bzw. dadurch erfolgen, daß der Kern 25 mit einer Feder bewegbar gelagert ist. Ein Träger 58 des Kernes 25 ist platten- bzw. rechtwinklig quer zur Achse 9 ringscheibenförmig, einteilig mit dem Kern 25 sowie wie dieser gesondert von der Einheit 5 bzw. dem Träger 20 ausgebildet. Dieser nimmt in einer Vertiefung versenkt den Träger 58 bzw. die zugehörig Einheit 60 auf, welche durch eine Schnappverbindung gesichert ist. Der Träger 58 wird als Tellerfeder in Richtung der Achse 9 verformt.7, the core part 25 controls the media flow on the Opening 8. The sleeve 25 consists of an opposite other materials softer resilient material. Under the Media pressure guides them with the seat 51 opposite the base body 2, 4 or the link 50 in the direction 40 an opening movement to open the closure 10. This can only be done by a resilient longitudinal extension of the core 25 or thereby take place that the core 25 is movably supported by a spring is. A carrier 58 of the core 25 is plate or rectangular transverse to the axis 9 in the form of an annular disk, in one piece with the Core 25 and like this separately from unit 5 or the carrier 20 is formed. This takes in a recess countersinks the carrier 58 or the associated unit 60, which is secured by a snap connection. The carrier 58 is deformed as a plate spring in the direction of axis 9.

Das äußere Ende 27 des Kernes 25 ist auch am Außenumfang stumpfwinklig konisch ausgebildet. Dieser konische Endabschnitt liegt mit Spaltabstand einem komplementären Innenkonus der Wand 24 gegenüber. Dieser Innenkonus schließt mit seiner engsten Stelle unmittelbar an den Endkanal 8 an. Der Sitz 51 und das Glied 50 weisen einen demgegenüber gleich großen oder etwas spitzeren Konuswinkel auf. Bei seiner Axialbewegung hebt der Sitz 51 vom Glied 50 ab. Dabei schlägt die Endwand des Teiles 25 an der Wand 24 an. Ein axialer Kanal 59, verbindet den Kanal 29 mit dem Spalt zwischen den Endwänden. Der Kanal 59 kann ausschließlich durch mindestens eine Nut am Innenumfang des Mantels 23 gebildet und entlang der offenen Nutlängsseite vom Außenumfang des abgestuft reduzierten Endabschnittes des Kernes 25 begrenzt sein. Dadurch ergibt sich eine Beschleunigung bzw. Verwirbelung des Mediums.The outer end 27 of the core 25 is also on the outer circumference obtuse-angled conical. This conical end section is a complementary inner cone with gap spacing the wall 24 opposite. This inner cone also closes its narrowest point directly to the end channel 8. Of the Seat 51 and link 50 have the same in contrast large or slightly more acute cone angle. With his Axial movement lifts the seat 51 from the link 50. Here strikes the end wall of part 25 against wall 24. A axial channel 59, connects the channel 29 to the gap between the end walls. Channel 59 can only by at least one groove on the inner circumference of the jacket 23 formed and along the open longitudinal side of the groove from the outer circumference of the stepped reduced end portion of the core 25 be limited. This results in an acceleration or Swirling of the medium.

Der Kern 26 kann hier starr gelagert sein, beispielsweise durch einteilige Verbindung mit der Einheit 5, 20. Diese Verbindung kann aber auch den federnden Abschnitt 37 in Form einer Zunge, Membran oder dgl. bilden und etwa in der Ebene der Platte 20 liegen. Der Abschnitt 37 bildet innerhalb des Gliedes 21 eine Stirnwand mit einem Durchlaß für das Medium. Der Träger 58 ist zwischen dieser Stirnwand und der Wand 41 axial eingespannt. Der Kanal 28 ist in Strömungsrichtung bis zum Sitz 51 durchgehend konisch verengt. The core 26 can be rigidly supported here, for example by one-piece connection with the unit 5, 20. This Connection can also form the resilient portion 37 a tongue, membrane or the like. Form and approximately in the plane the plate 20 lie. The section 37 forms within the Link 21 an end wall with a passage for the medium. The carrier 58 is between this end wall and the wall 41 axially clamped. The channel 28 is in the direction of flow tapered to seat 51 throughout.

Die Rückfederung des Ventilsitzes 51 zur Schließstellung kann auch so vorgesehen sein, daß zu Beginn der Austragbetätigung zunächst sehr viel Luft in die Öffnung 8 strömt, dann bei gleichzeitiger Reduzierung dieses Luftstromes der Medienstrom beginnt und im Anschluß an dessen Beendigung die Luftströmung nochmals erhöht wird.The spring back of the valve seat 51 to the closed position can also be provided so that at the beginning of the discharge operation first a lot of air flows into the opening 8, then at simultaneous reduction of this air flow the media flow begins and after the air flow ends is increased again.
