, DETAILED DESCRIPTION OF T~ PREFERRED EMBODIMENTS
Referring now to the drawings, the preferred embodiments of the present invention are shown. Referring to Fig. 1, a prior art coupling assembly 10 is shown. The coupling 10 is connected to an au~omotive air conditioning compressor 12. The compressor 12 is attached to a drive belt 14. The compressor 12 is held in place on an automobile (not shown) by a bracket 16. The compressor is used to move refrigerant and change the pressure of the refrigerant in an automotive air conditioning system.
The prior art coupling assembly 10 includes a flange 1B and tubes or conduits 20 and 20'. The tubes 20 and 20' transport the refrigerant to the air conditioning system. The tubes 2û and 20' are permanently and fixedly connected to the flange 18 by welds or brazes 22. This prior art connection does not allow the tubes 20 and 20' to move with respect to the flange 18. This creates a problem when the belt 14 has to be adjusted or changed. In order to overcome~this problem, flexible hoses 24 and 24' are attached to the prior art tubes 20 and 20', respectively, to allow the compressor 12 to be moved to adjust or change the belt 14. It has been found, however, that the use of flexible hoses is disadvantageous because of the inability to maintain a good seal between the tubes 20 and 20' and the flexible hoses 24 and 24', respectively. It has also been found that the flexible hoses can de~eriorate over time.
The prior art coupling assembly shown in Fig. 1 has also been found to be difficult to assemble. Further, this type of coupling assembly when attached to, for example, a compressor is expensive and cumbersvme to package because the package must be enlarged to con~ain ~he immovable tubes.

Wo93/22594 : PC~/US93/02910 The coupling assembly 30 of the present invention is shown in;
Fig. Z. In Fig. 2, the assembly 30 is shown as being attached to an automotive air conditioning compressor 12 by way of example.
However, the present invention can be attached to any suitable fluid transport unit depending on the application. The compressor ~2 is attached to a drive belt 14 and a bracket 16.
The present invention includes a flange 32 and at least one tube 34. As described below in detail, the tubes 34 and 34' are movable with respect to the flange 32. This allows the compressor to be moved sufficiently to adjust or change the drive belt 14. It also allows for relatively simple manufacture of the coupling assembly and relatively inexpensive packaging of the unit to which the assembly is attachcd~
Referring to Fig. 3, the coupling assembly 30 includes a flange 32. The flange 32 has an outer surface 40 and at ieas~ one inner surface 42. In the present smbodiment, the flange 32 has two inner surfaces 42 and 4~'. The flange 32 further includes at least one tube receiving opening ~4 defined by the inner surface 42. In the present embodiment, there are two tube receiving opening 44 and 44' defined by the inner surfaces 42 and 42', respectively. The flange 32 also includes flange groves 46 and 46' defined by inner surfaces 42 and 42', respectively. The flange 32 further includes two O ring receiving grooves 48 and 48' defined by the inner surfaces 42 and 42', respectively, of the flange.
Still referring to Fig. 3, the flange 32 has at least one tube connection means hole 50 extending through the fiange from the outer surface 40 to the inner surface 42. The hole ~0 is in communication with the flange groove 46. In the present embodiment, there are two holes 50 and 50' in communication with flange grooves 46 and 46', respectively.
WO 93t22594 ` Pc~r~US93/O~9l~J
21331Si - 6 -The flange 32 ;ncludes a bolt receiving opening 52. A bolt 54 is inserted through the operling~52 t~attach the flange to the exterior surface of the compressor 1 2-a~ In the presen~ embodiment, a compressor attachment flange 5~ is positioned between the flange 32 and the compressor 12. 1 lowever, it should be understood that the flange 32 can be attached directly to the compressor 12 or the flange 32 can be an integral part of the compressor unit as rnore clearly shown in Figs. 13 and 15.
The flange 32 can be made of any suitable material. It has been found ~hat metal-and plastic are preferred. If the flange is integral wi~h a fluid transport unitl such as a eompressor, the flange can be injection molded wit~ a plastic material directly on the unit.
Referring to Fig. 3, the coupling assembly 30 includes at least one tube 6Q. In the present embodiment, two tubes 60 and 60' are t 5 shown. Each tube has an exterior surface 62 and 62', respectively.
Each tube also has tube grooves 64 and 64' defined by the exterior surfaces 62 and 62', respectively. In this embodiment, the tube ~rvove 64 is an annular groove extending around the exterior surface 62 of the tube 60.
The ends of the tubes 60 and 60' are inser~ed in the tube receiving openings 44 and 44', respectively, of the flange 32. When the tubes are inserted in the tube receiving openings, the ~ube grooves 64 and 64' are aligned with the flange grooves 46 and 46', respectively. When the grooves are so aligned, ~hey form an annular chamber.
The tubes 60 and 6û' can be made of a variety of materials.
It has been found that metal and plastic are suitable materials, with me~al being preferred.
Still referring to Fig. 3, the coupling assembly 30 includes a tube connection means 70. In the embodiment shown in Fig. 3, the connection means 70 is a U-shaped wire. The connection means 70 Wo 93/22~9~ 2 1 3 3 ? 5 1 P~/USg3/02gl0 includes legs 72 and 72' and drive portion 74. The drive portion aids in the insertion of the legs 72 and 72' during assembiy. The wire can be made of a variety of materials, with a flexib~e metal - being preferred.
As shown in Figs. 4-7, the tube connection means 70 can be inserted in the tube connection means holes 50 and 5Q' in a variety of ways depending on the application. In Fig. 4, leg 72 is inserted in tube connection me~ns hole 50 that is located near the center of the flange 32. Leg 72' is inserted in hole 50' that is near the outside of the flange 32. When legs 72 and 7Z' are inserted in the holes 50 and 50', respectively, the legs mate with the flange grooves 46 and 46' and ~he tube grooves 64 and 64' by encircling the respective grooves or at least partially encircling such grooves. This mating arrangement acts to retain the tubes 6C~ and 60' in moving engagement with the 1~ flange 32. The tubes 60 and 60' are free to rotate wi~hin the flange 32. Once the legs 72 and 72' have been fully inserted, the drive portion 74 can be removed from the legs.
Referring to Fig. 5, the tube connection means holes 50 and 50' are both located near the outside of ~he flange 32. As shown in Fig. 6, the holes 50 and 50' are both iocated near the cen~er of the flange 32.
Referring to Fig. 7, the tube connection means 7û can be wire pins having legs 72 and 72' and drive portions 74 and 74' in the form of heads. The pins are inserted in the tube connection means holes 50 and 50' by applying force to the drive portions 74 and 74'. Once inserted, the drive portions 74 and 74' are flush with the outer surface 40 of the flange 32. If desired, the drive portions 74 and 74' can be removed after insertion.
Referring to Fig. 14, the tube connection means can be two U-shaped wires 71 and 71' having legs 73 and 73', and 75 and 75', respectively. The legs 73 and 73' are inserted in holes 51 and 51', wo 93/22s~4 P~r/uS93fO2~10 2~337S1 - 8 -respectively, and the le~s 75 and 75' are inserted in holes 53 and 53'~ respectively. The holes 51, 51', 53 and 53' extend completeiy through the flange 32. in this embodtment, the legs do not en-circle the flange grooves 46 and ~6' or the tube grooves 64 and 64'.
Instead, the legs partially engage the grooves to retain the tubes in moving engagement with the flange 32.
Referring to Figs. 3 and 8-12, the coupling assembly 30 can include at least one tube O-ring 80 positioned in an O-ring groove 4~
on the flange 32. The tube O-ring provides a seal between the flange 32 and the exterior surface 62 of the tube 60. An additional flange O-ring 82 can be positioned in a space 84 defined by the compressor 12. The space 84 can also be defined by the compressor flange 56 ; ;~ as shown in Fig. 3. The O-rings can be made of any suitable elastomeric material.
Referring to Fig. 8, two pairs of tube O-rings 80 and 80' are posi~ioned in two pairs of O-ring grooves 48 and 48', respectively.
Two flange O-rings 82 and 82' are positioned in spaces 84 and ~4', respectively, defined by the compressor unit 12. As shown in Fig.
12, single tube O-rings 80 and 80' can be positioned in the O-ring grooves 4~ and 48', respectively.
Referring to Fig. 9, a plurality of chevron shaped seals 90 can be used in place of the above described tube O-rin~s ~0. The seals 90 are positioned in a seal groove 92 defined by the inner surface 4 of the flange 32.
Referring to Fig. 10, the tube groove 64, as described above, can be replaced by a groove formed by the junction of two sections of the ~ube 60. In this embodiment, a first section 96 of the tube has a diameter larger than the adjacent second section 98 of the tube.
Thus, the tube groove, or the area around which the leg 72 mates, is the junction 100 of the first section 96 and second section 98.
:' wo 93/22s94 2 1 3 3 7 5 1 PC~/VS93/~9}0 g Referring to Fig. 11, the second section 98 of the tube 60 can include an enlarged portion 102 adjacent to the tube groove 64. The enlarged portion 102 is positioned in an enlarged portion groove 104 defined by the inner surface 42 of the flange 32.
Referring to Fig. 13, the flange 32 can be integral with a fluid transport unit such as a compressor 12. In this embodiment, the flan~e 32 extends outwardly from the exterior surface 106 of the compressor unit 12. When the flange 32 is integral with the compressor unit 12, there is no need for flange 0-rings. There are usually at leas~ one pair of tube 0-rings 80 positioned in 0-ring grooves 48.
Referriny to Fig. 15, the tube 0-rings 80 and 80' can be positioned in 0-ring receiving channels 110 and 110', respectively.
Th~ channeis are defined by the exterior surfaces 62 and 62' of tubes 60 and 60', respectively. In this embodiment, the 0-ring receiving channels replace the 0-rin~ receiving groove 48 of the flange 32.
It should be understood that many changes can be made to the coupling assemb!y disclosed in the drawings and still fall within the ~: ~ scope of the following claims.

Once inserted, the drive portions 74 and 74' are flush with the outer surface 40 of the flange 32. If desired, the drive portions 74 and 74' can be removed after insertion.
Referring to Fig. 14, the tube connection means can be two U-shaped wires 71 and 71' having legs 73 and 73', and 75 and 75', respectively. The legs 73 and 73' are inserted in holes 51 and 51', wo 93/22s~4 P~r/uS93fO2~10 2~337S1 - 8 -respectively, and the le~s 75 and 75' are inserted in holes 53 and 53'~ respectively. The holes 51, 51', 53 and 53' extend completeiy through the flange 32. in this embodtment, the legs do not en-circle the flange grooves 46 and ~6' or the tube grooves 64 and 64'.
Instead, the legs partially engage the grooves to retain the tubes in moving engagement with the flange 32.
Referring to Figs. 3 and 8-12, the coupling assembly 30 can include at least one tube O-ring 80 positioned in an O-ring groove 4~
on the flange 32. The tube O-ring provides a seal between the flange 32 and the exterior surface 62 of the tube 60. An additional flange O-ring 82 can be positioned in a space 84 defined by the compressor 12. The space 84 can also be defined by the compressor flange 56 ; ;~ as shown in Fig. 3. The O-rings can be made of any suitable elastomeric material.
Referring to Fig. 8, two pairs of tube O-rings 80 and 80' are posi~ioned in two pairs of O-ring grooves 48 and 48', respectively.
Two flange O-rings 82 and 82' are positioned in spaces 84 and ~4', respectively, defined by the compressor unit 12. As shown in Fig.
12, single tube O-rings 80 and 80' can be positioned in the O-ring grooves 4~ and 48', respectively.
Referring to Fig. 9, a plurality of chevron shaped seals 90 can be used in place of the above described tube O-rin~s ~0. The seals 90 are positioned in a seal groove 92 defined by the inner surface 4 of the flange 32.
Referring to Fig. 10, the tube groove 64, as described above, can be replaced by a groove formed by the junction of two sections of the ~ube 60. In this embodiment, a first section 96 of the tube has a diameter larger than the adjacent second section 98 of the tube.
Thus, the tube groove, or the area around which the leg 72 mates, is the junction 100 of the first section 96 and second section 98.
