DETAILED DESCRIPTION
[0043]
[0044] The sealing body 5 has a sealing body internal section 33 and a sealing body edge region 31 surrounding the sealing body internal section 33.
[0045] The sealing body 5 has, in the region of its sealing body edge region 31, a groove 7 surrounding the sealing body edge region 31. In the region of the groove 7, at least one, preferably, two, three or more than three sealing lip/sealing lips 8 is/are formed which encircle the sealing body edge region 31 in the region of the groove 7 and face radially outwardly.
[0046] The sealing body 5 further comprises a first sealing body side 29 facing in the first direction 15 and a second sealing body side 30 facing in the second direction 18. The sealing body edge region 31, particularly in the region of the second sealing body side 30, axially extends in the second direction 18 and is designed curved radially inwardly to a plane formed by the second sealing body side 30, at an angle of less than 90. In alternate embodiments, the sealing body edge region 31 is not curved.
[0047] In the embodiment shown in
[0048] In the area of the sealing body edge region 31, at least one shaft-like second recess 35 is arranged, which substantially axially protrudes in the second direction 18 from the first sealing body side 29 to the second sealing body side 30. In the area of the first sealing body side 29, the at least one second recess 35 thereby forms a shaft opening. In the area of the second sealing body side 30, the at least one second recess 35 forms a ridge, which is arranged particularly in the region of the at least one tab-like device 36. The number of second recesses 35 can vary in different embodiments. In addition, the second recess 35 may also be omitted.
[0049] In
[0050] The number of ridges 10 and the number of frame edges 11, 19 may vary in different embodiments. The at least one ridge 10 is formed such, that it fits into the at least one second recess 35 formed in the sealing body 5 not shown in
[0051]
[0052] In an area positioned between the first frame edge 11 and the second frame edge 19, the frame 9 has a number of partially uniformly and partially unevenly spaced plug openings 28. Through the individual plug openings 28 and formed in the sealing body edge region 31 on the first sealing body side 29, a plug button 32 in each case projects through the frame 9. The plug buttons 32 are in particular formed in one piece with the sealing body 5 and have a detent 48 at its end facing away from the sealing body 5. The detent 48 is thereby inserted into the plug opening 28 and holds the plug button 32 in the plug opening 28. The number, shape and spacing of the plug buttons 32, as well as of the corresponding plug openings 28, will vary in different embodiments.
[0053] In the area of the second frame edge 19, a number of evenly and/or unevenly spaced fixing holes 37 are arranged. The individual fixing holes 37 are each suitable for inserting a holding element 25, in particular a screw.
[0054] The sealing body 5 has four first lead-through openings 6. Tubes 3 also not shown in
[0055]
[0056] The frame 9 has three fixing holes 37 in the region of its second frame edge 19 which serve to fasten the frame 9 on the wall 4 not shown in
[0057] In this case, the frame 9 has a peripheral shape which is substantially congruent with the peripheral shape of the sealing body edge region 31. The peripheral shape of the frame 9 can have different shapes in different embodiments. The peripheral shape of the sealing body edge region 31 may also vary or deviate from the peripheral shape of the frame 9.
[0058] In the region of the sealing body internal section 33 and adjacent to the first sealing body lateral side 40, two first lead-through openings 6 are formed, each having an everted collar 46 projecting in the first direction 15. One of these first two lead-through openings 6 is also disposed adjacent to the second sealing body longitudinal side 24. The other of the two first lead-through openings 6 disposed adjacent to the first sealing body lateral side 40 is also disposed adjacent to the first sealing body longitudinal side 23. The first lead-through opening 6, which is disposed adjacent to the second sealing body longitudinal side 24 and adjacent to the first sealing body lateral side 40, serves as the first lead-through opening 6 for the insertion of a tubular refrigerant flow. This first lead-through opening 6 has a diameter which is approximately twice as large as the diameter of the first lead-through opening 6, which is disposed adjacent to the first sealing body lateral side 40 and adjacent to the first sealing body longitudinal side 23 and which serves for the insertion of a tubular refrigerant feed.
[0059] In the region of the sealing body internal section 33 and adjacent to the second sealing body lateral side 41, in this embodiment, two further first lead-through openings 6 are formed, each with an everted collar 47 projecting in the second direction 18. In addition, one of these two further first lead-through openings 6 is disposed adjacent to the second sealing body longitudinal side 24. The other of the two further first lead-through openings 6 disposed adjacent to the second sealing body lateral side 41 is also disposed adjacent to the first sealing body longitudinal side 23. These two further first lead-through openings 6 each serve for the insertion of a tubular inlet for a coolant and/or the insertion of a tubular outlet for a coolant, and the diameters of these two further first lead-through openings 6 are mutually approximately the same size. In alternative embodiments, the diameter and the configuration mentioned may vary.
[0060] The number and arrangement of the fixing holes 37 shown in
[0061] In the assembled state of the sealing arrangement, tubes 3 are inserted through the four first lead-through openings 6, which in particular serve for the inlet and outlet of a refrigerant and/or the inlet and outlet of a coolant. Surface structures are formed adjacent to and/or in the region of the first lead-through openings 6 in the region of the first sealing body side 29 and/or in the region of the second sealing body side 30. These surface structures are formed such, that they substantially run along the periphery of the first lead-through openings 6.
[0062] In this regard, surface structures, for example, folds 45 in the area of the first lead-through openings 6 and/or everted collars 46 projecting in the first direction 15 and/or everted collars 47 projecting in the second direction, can be formed. These surface structures are particularly suitable for increasing the tightness between said tubes 3 and the sealing body 5 in the area of the first lead-through openings 6 as well as for facilitating the insertion of the tubes 3 through the sealing body 5 during assembly.
[0063]
[0064] The first frame edge 11 engages in a first recess 34 formed on the first sealing body side 29 substantially as a surrounding gap which is disposed running radially in the region between the sealing body internal section 33 and the sealing body edge region 31. The frame 9 thereby carries the sealing body 5.
[0065] The groove 7 is formed in the second direction 18, axially rearward of the plug buttons 32 in the area of the sealing body edge region 31. In the region of the groove 7, three sealing lips 8 are arranged in the embodiment shown in
[0066]
[0067]
[0068]
[0069] The dividing wall 4 has a passage in the area of the opening 2, facing in the second direction 18. In the edge region 12 of the opening 2, the passage forms a bearing surface arranged substantially parallel to the groove 7, which the sealing lips 8 bear against. The sealing lips 8 are arranged in the region of the channel-like frame structure 27, and in a bent manner sealingly abut the bearing surface formed by the passage at different angles to a plane formed by the groove 7. The second frame edge 19 rests directly on the first wall side 13.
[0070]
[0071]
[0072] The groove 7 is formed in the second direction 18, axially rearward of the detents 48 and the plug buttons 32, in the region of the sealing body edge section 31. In the area of the groove 7, in the embodiment illustrated in
[0073]
[0074] The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
