  • the present invention relates to a hermetic 'compressor comprising a casing containing a compressor and motor and being provided with steel tube connectors for adhesively attaching the compressor to a refrigeration system, and more particularly to a sealing assembly for sealing the compressor casing and the outer surface of the tube connector from possible outside contamination during the high pressure leak testing, manufacturing and storing procedures prior to its connection'to a sealed refrigeration system.
  • the sealing assembly includes a pair of resilient sealing members arranged on the tube connector, a cap member and latching means including tab means and ridge means that remo'vably connects the cap"mernber to the tube connector.
  • the resilient sealing members are placed on the tube connector andthe cap placed over the tube connector to engage the resilient members.'The cap is driven down until the latching means is adjacent the ridge means and the cap is then crimped to latch the cap to the tube connector thereby maintaining the resilient sealing rnembers in a sealed position.
  • the cap is removed from the tube connector by prying the latching means from the holding' c ap away from the tube connector when thecompressor ready to be connected to a refrigeration system, The above arrangement being effective to maintain the: sealing arrangement during the compressor testing operation wherein the casing is pressurized.
  • the present invention is directed particularly to a compressor positioned in a casing. including a connec tor having a passageway connecting with the'compressor.
  • the connector includes atube portion and an en larged annular flange portion.
  • a resilient sealing ring is arranged on the flange and a resilient tube seal extends into the connector tube to seal the passageway.
  • the tube seal has a collar portion which engages the outer end of connector tube.
  • a cover including a tubular cap portion is positioned over said tube connector and its closed end engages said collar portion of the tube seal while a circumferentially disposed outwardly projecting sealing surface engages the resilient sealing ring to seal the outer surface of the connector.
  • the cover is latched to the connector tube by a plurality of tabs arranged to removably engage a ridge to compress and maintain said collar portion in engagement with the outer end of said tube portion and said sealing ring in engagement with said sealing surface.
  • FIG. 1 is an elevational view of a hermetic refrigeration compressor incorporating the present invention
  • FIG. 2 is an enlarged sectional view illustrating the construction of the tube seal assembly
  • FIG. 3 is an exploded disassembled perspective view of the tube seal assembly.
  • a rotary compressor 10 comprising a casing 12 in which there is a compressor 14 and motor (not shown).
  • the compressor casing is provided with means for connecting the compressor to a refrigeration system.
  • connector 16 in both the suction inlet and an outlet.
  • a suction passage 17 of the compressor 14 extends to the wall of the casing 12 and communicates with an opening 18 therein. While FIG. 2 illustrates the suction tube assembly, it should be noted that the inlet and outlet connectors 16 are identical.
  • the connector assembly comprises a tubular steel connector or conduit 19 secured to the compressor casing 12.
  • the steel connector 19 has a tubular body portion 20 to which the refrigeration system is adhesively joined and a flange 21 from which a reduced end portion 22 extends into or through the hole 18 in the casing 12
  • the end portion 22 is preferably of frustrum configuration and is Welded to the casing 12 as indicated to form a fluid tight seal between the casing 12 and the connector 19.
  • a connector tube sealing assembly 24 which comprises a cylindrical cap or cover member 26, a resilient sealing ring 28, a resilient tube seal member 30, and a circumferentially disposed ridge portion 32 formed on the peripheral wall 34 of the flange 21 of the connector tube 20.
  • the resilient sealing ring means is arranged on the shoulder portion 36 of the flange 21 and as will be explained hereinafter provides a seal for the outer surface of body portion 20.
  • the resilient tube seal 30 has a tubular end portion 38 which is dimensioned to be press fit in the passageway of the tube connector 19, to provide a seal, and a shoulder portion 40 for engaging the free end 42 of the tubular connector 19 to seal the compressor casing 12 from outside contamination.
  • the body portion 38 of member 30 has a diameter larger than the passageway of the connector 19.
  • the seal is provided with a hole or recess 31 into which an appropriate tool may be inserted to press the end portion 38 into the passageway of the connector 19 until the shoulder portion 40 is against the free end of the connector 19.
  • the cover member 26 includes a tubular portion 44 having a closed end 46 that engages the shoulder por-.
  • the tube sealing assembly 24 must remain effective through the testing and evacuation procedures, and the required internal pressures and temperatures which are indicated below.
  • Means are provided in the present embodiment to removably connect the cover member 26 to the tube connector 19.
  • annular wall 50 projecting from the sealing surface portion 48 of the cover 26.
  • the wall 50 is arranged to be adjacent the wall 34 and more particularly adjacent the ridge 32.
  • the free end of the annular wall 50 includes a flared end 52.
  • detents or tabs 54 are dimensioned in their normal free position to pass by the ridge 32.
  • the wall 50 including the tabs 54 is then crimped until the tabs 54 engage over the ridge 32 of the tube connector.
  • the engagement of the tabs 54 with the ridge 32 is effective to maintain the sealing ring 28 and collar portion 40 in sealing engagement between the cover 26 and the tube connector 20 for sealing the compressor casing 12 from possible outside contamination during the following procedure prior to its connection to a refrigeration system.
  • To remove the sealing assembly when required it is only necessary to pry the flared end 52 away from the casing 12 by any suitable tool until the tabs 54 snap over the ridge 2].
  • a hermetic compressor unit comprising:
  • a compressor positioned in a casing including a side wall having at least one opening and a connector having a passageway communicating with said opening;
  • said connector including a tube portion and an enlarged annular flange portion on one end forming a shoulder portion and a circumferentially disposed peripheral wall portion;
  • a resilient tube seal dimensioned to extend into intimate contact with the inner surface of said tube passageway, and having a collar portion engaging the outer end of said tube portion;
  • cover means including a tubular cap portion positioned over the outer surface of said tube portion having a closed end engaging said collar portion of said tube seal and a circumferentially disposed outwardly projecting sealing surface engaging said resilient sealing means;
  • latching means including means on one of said wall portions being arranged to removably engage means on the other of said wall portions to compress and maintain said tube seal in said passageway and said collar portion in engagement with the outer end of said tube portion and simultaneously maintain said sealing ring in engagement with said sealing surface to seal the outer surface of said connector.
  • said latching means includes a plurality of tab means spaced radially on one of said wall portions being arranged to removably engage ridge means on the other of said wall portions.
