Abstract
Description
Die Erfindung betrifft eine Radialpumpe mit einem in einem Gehäuse drehbar gelagerten Laufrad, mit einem Spaltringschieber, welcher zwischen dem Laufrad und einem Austrittsbereich axial verfahrbar ausgebildet ist, wobei der Spaltringschieber um die Achse des Laufrades drehbar und axial verschiebbar im Gehäuse gelagert ist, wobei zwischen dem Spaltringschieber und dem Gehäuse eine gewinde- oder rampenartige Führung angeordnet ist und wobei der Spaltringschieber mit einer Verdreheinrichtung verbunden ist.The The invention relates to a radial pump with a rotatable in a housing mounted impeller, with a split ring valve, which between the impeller and an outlet region formed axially movable is, wherein the split-ring slide rotatable about the axis of the impeller and axially displaceably mounted in the housing, wherein between the split ring and the housing a threaded or ramp-like Guide is arranged and where the split ring valve connected to a twisting device.
Es ist bekannt, Radialpumpen mit Spaltringschiebern auszuführen. Diese haben den Zweck, bei abgesperrter Pumpendruckleitung, aber weiterlaufender Pumpe das Laufrad gegen das Druckgehäuse durch eine glatte Wand abzusperren und auf diese Weise die hydraulischen Verluste möglichst gering zu halten. Das Verstellen des Spaltringschiebers erfolgt zumeist hydraulisch durch Servomotoren oder elektrisch über Elektromagnete.It is known to perform radial pumps with split gate valves. These have the purpose, with shut off pump pressure line, but Continuing pump through the impeller against the pressure housing to shut off a smooth wall and in this way the hydraulic To keep losses as low as possible. Adjusting the Spaltringschiebers is usually done hydraulically by servomotors or electrically via electromagnets.

Der Nachteil der bekannten Radialpumpen ist, dass zum Verschieben der Spaltringschieber im Gehäuse ein Austrittsbereich, bzw. ein Elektromagnet erforderlich ist, was relativ viel Bauraum in Anspruch nimmt.Of the Disadvantage of the known radial pumps is that to move the Spaltringschieber in housing a discharge area, or an electromagnet is required, giving a relatively large amount of space in Claim takes.
Aufgabe der Erfindung ist es, diesen Nachteil zu vermeiden und eine kompakte Radialpumpe mit Spaltringschieber zu realisieren, wobei Leckagen sicher vermieden werden sollen.task The invention is to avoid this disadvantage and a compact Radial pump with split-ring valve to realize leaks safely avoided.
Erfindungsgemäß wird dies dadurch erreicht, dass zwischen dem Spaltringschieber und dem Gehäuse zumindest ein erstes Dichtelement angeordnet ist und zumindest ein zweites Dichtelement an einer laufradseitigen Stirnfläche des Spaltringschiebers angeordnet ist. Durch die Dichtelemente können Leckagen sicher vermieden werden.According to the invention this is achieved in that between the split ring valve and the Ge housing at least a first sealing element is arranged and at least a second sealing element is arranged on an impeller-side end face of the split-ring slide. Through the sealing elements leaks can be safely avoided.
Die gewinde- oder rampenartige Führung mehrgängig ausgebildet ist. Um die Verschmutzungsempfindlichkeit zu vermindern, kann die gewinde- oder rampenartige Führung auch eingängig ausgebildet sein.The thread or ramp-like leadership more often is trained. To reduce the sensitivity to pollution, The thread or ramp-like leadership can also be catchy be educated.
Die gewinde- oder rampenartige Führung kann an einer äußeren Mantelfläche oder an einer inneren Mantelfläche des Spaltringschiebers angeordnet sein.The thread or ramp-like guidance may be at an outer Lateral surface or on an inner lateral surface be arranged of the split ring valve.
Die Dichtelemente können als O-Ringdichtungen ausgebildet sein.The Sealing elements may be formed as O-ring seals.
Besonders kleine Betätigungskräfte lassen sich erreichen, wenn die Dichtelemente als Lippendichtungen ausgebildet sind. Die Lippendichtungen werden nach Schließen des Gleitringschiebers zu Folge der Druckdifferenz beidseits der Dichtlippen gegen die Wand des Gehäuses gepresst. Die Lippendichtungen können dabei durch ein beispielsweise in einem Spritzvorgang einstückig mit dem Gleitringschieber ausgebildetes Elastomerelement gebildet sein.Especially small operating forces can be achieved when the sealing elements are designed as lip seals. The Lip seals become when the slide ring slide closes due to the pressure difference on both sides of the sealing lips against the Wall of the housing pressed. The lip seals can doing so by a piece, for example, in an injection process formed with the slide ring slider formed elastomeric element be.
In einer ersten bevorzugten Ausführungsvariante der Erfindung ist vorgesehen, dass die Verdreheinrichtung eine im Gehäuse quer zum Spaltringschieber geführte Verstellstange aufweist, welche gelenkig, vorzugsweise über einen Zylinderstift, mit dem Spaltringschieber verbunden ist.In a first preferred embodiment of the invention is provided that the twisting device in the housing has adjusting bar guided transversely to the split-ring slide, which articulated, preferably via a cylindrical pin, with the split ring valve is connected.
Alternativ dazu kann vorgesehen sein, dass die Verdreheinrichtung eine im Gehäuse quer zum Spaltringschieber geführte Zahnstange aufweist, welche in eine Verzahnung des Spaltringschiebers formschlüssig eingreift.alternative For this purpose, it can be provided that the twisting device in the housing has transverse to the split ring slide guided rack, which in a toothing of the split ring valve positive fit intervenes.
Eine kompakte Bauweise des Gehäuses der Radialpumpe wird dadurch möglich, dass die Verstellstange oder die Zahnstange aus dem Gehäuse herausgeführt ist. Dadurch kann die eigentliche Betätigungsvorrichtung außerhalb des Gehäuses der Radialpumpe angeordnet werden.A Compact design of the housing of the radial pump is characterized possible that the adjusting rod or the rack off led out of the housing. This allows the actual actuator outside of Housing the radial pump can be arranged.
Eine besonders einfache und platzsparende Betätigung ergibt sich, wenn die Verdreheinrichtung pneumatisch, vorzugsweise über eine Vakuumdose, oder elektrisch, mechanisch oder hydraulisch betätigbar ist.A particularly simple and space-saving operation results when the twister pneumatic, preferably over a vacuum box, or electrically, mechanically or hydraulically actuated is.
Durch das druckseitige Verschließen der Radialpumpe mittels des Spaltringschiebers können – bei Anwendung als Kühlmittelpumpe in einem Kraftfahrzeug – die Warmlaufzeiten wesentlich reduziert werden.By the pressure-side closing of the radial pump by means of Split ring valves can - when used as Coolant pump in a motor vehicle - the warm-up times be significantly reduced.
