Compressor

Abstract

A compressor includes a housing, a suction passage, a compression unit, a drive unit, a suction piping and a thermal insulating member. The housing forms a configuration of the compressor. The suction passage is formed in the housing for introducing a suction gas. The compression unit is provided in the housing for compressing the suction gas. The drive unit is provided in the housing for driving the compression unit. The suction piping is attached to the housing for connecting to the suction passage. The thermal insulating member is interposed between the housing and the suction piping for preventing heat transfer from the housing to the suction piping, and the thermal insulating member has a through hole which interconnects the suction passage and the suction piping.

1 . A compressor comprising: 
 a housing for forming a configuration of the compressor;    a suction passage formed in the housing for introducing a suction gas;    a compression unit provided in the housing for compressing the suction gas;    a drive unit provided in the housing for driving the compression unit;    a suction piping attached to the housing for connecting to the suction passage; and    a thermal insulating member interposed between the housing and the suction piping for preventing heat transfer from the housing to the suction piping, the thermal insulating member having a through hole which interconnects the suction passage and the suction piping.    
   
   
       2 . The compressor according to  claim 1 , wherein thermal conductivity of the thermal insulating member is lower than that of the housing.  
   
   
       3 . The compressor according to  claim 1 , wherein the housing is made of metallic material of aluminum series, the thermal insulating member being made of one of material of resin series and metallic material of iron series.  
   
   
       4 . The compressor according to  claim 1 , wherein the thermal insulating member and the suction piping are combined with each other.  
   
   
       5 . The compressor according to  claim 1 , further comprising a thermal insulating tube provided In the suction passage, the thermal insulating member and the thermal insulating tube being integrally formed with each other.  
   
   
       6 . The compressor according to  claim 5 , wherein the suction passage and the thermal insulating tube form a space therebetween.  
   
   
       7 . The compressor according to  claim 5 , wherein a diameter of the through hole of the thermal insulating member coincides with an inside diameter of the suction piping and an inside diameter of the thermal insulating tube.
