Compressor

Abstract

A compressor has therein a suction chamber into which refrigerant gas is introduced, a compression chamber in which the refrigerant gas in the suction chamber is introduced and compressed, and a discharge chamber into which the compressed refrigerant gas is discharged from the compression chamber. The suction chamber and the discharge chamber are formed adjacent to each other while being separated by a partition wall. At least one surface of the partition wall is provided with a thermal insulator which is formed by curing a thermal insulation coating composition. The thermal insulator includes hollow beads and one or more binder resin selected from the group consisting of epoxy resin, polyamide-imide resin, phenolic resin, and polyimide resin.

What is claimed is: 
     
         1 . A compressor comprising:
 a suction chamber into which refrigerant gas is introduced;   a compression chamber in which the refrigerant gas in the suction chamber is introduced and compressed; and   a discharge chamber into which the compressed refrigerant gas is discharged from the compression chamber, the suction chamber and the discharge chamber being formed adjacent to each other while being separated by a partition wall, wherein   at least one surface of the partition wall is provided with a thermal insulator which is made by curing a thermal insulation coating composition, and   the thermal insulator includes hollow beads and one or more binder resins selected from the group consisting of epoxy resin, polyamide-imide resin, phenolic resin, and polyimide resin.   
     
     
         2 . The compressor according to  claim 1 , wherein the hollow beads have a breaking strength of 3 MPa or more. 
     
     
         3 . The compressor according to  claim 1 , wherein the hollow beads comprise a sodium aluminosilicate glass. 
     
     
         4 . The compressor according to  claim 1 , the compressor using polyalkylene glycol or polyol ester as the lubricant. 
     
     
         5 . The compressor according to  claim 1 , wherein the thermal insulator is provided at least on a surface of the partition wall facing the discharge chamber. 
     
     
         6 . The compressor according to  claim 1 , wherein
 the partition wall includes a suction chamber wall disposed on the suction chamber side and a discharge chamber wall disposed on the discharge chamber side, the suction chamber wall and the discharge chamber wall being disposed apart from each other and filled with the thermal insulator therebetween.   
     
     
         7 . The compressor according to  claim 1 , wherein the suction chamber is disposed so as to surround the discharge chamber. 
     
     
         8 . The compressor according to  claim 1 , the compressor being used in a vehicle air conditioning system.
