Sealing member of a compressor

Abstract

A coat of material impermeable to coolant gas is formed on the surface of a sealing member of a compressor for absorbing and compressing the coolant gas.

1 . A sealing member of a compressor for absorbing and compressing coolant gas, wherein a coat of material impermeable to coolant gas is formed on the surface of the sealing member.  
   
   
       2 . A sealing member of  claim 1 , wherein the material of the coat is soft metal.  
   
   
       3 . A sealing member of  claim 1 , wherein the material of the coat is ceramic.  
   
   
       4 . A sealing member of  claim 1 , wherein the material of the coat is amorphous hard carbon.  
   
   
       5 . A sealing member of  claim 1 , wherein the material of the coat is high polymer material.  
   
   
       6 . A sealing member of  claim 5 , wherein the high polymer material is polyethylene.  
   
   
       7 . A sealing member of  claim 5 , wherein the high polymer material is polytetrafluoroethylene.  
   
   
       8 . A compressor for absorbing and compressing coolant gas comprising a sealing member, wherein a coat of material impermeable to coolant gas is formed on the surface of the sealing member.  
   
   
       9 . A compressor of  claim 8 , wherein the material of the coat is soft metal.  
   
   
       10 . A compressor of  claim 8 , wherein the material of the coat is ceramic.  
   
   
       11 . A compressor of  claim 8 , wherein the material of the coat is amorphous hard carbon.  
   
   
       12 . A compressor of  claim 8 , wherein the material of the coat is high polymer material.  
   
   
       13 . A compressor of  claim 12 , wherein the high polymer material is polyethylene.  
   
   
       14 . A compressor of  claim 12 , wherein the high polymer material is polytetrafluoroethylene.  
   
   
       15 . A compressor of  claim 8  further comprising a rotating shaft, a compressing mechanism driven by the rotating shaft, a housing for accommodating the rotating shaft and the compressing mechanism, and a shaft seal member, wherein the sealing member is the shaft seal member.  
   
   
       16 . A compressor of  claim 8  further comprising a rotating shaft, a compressing mechanism driven by the rotating shaft, and a housing for accommodating the rotating shaft and the compressing mechanism, wherein the housing is an assembly of a plurality of partial housings, gaskets are inserted into joints of the partial housings, and the sealing member is one of the gaskets.
