Compressor

Abstract

A compressor has a front housing, a rear housing, a plurality of bolts, and a rigid plate. The rear housing is connected to the front housing. The bolts connect the front housing and the rear housing in an axial direction. The rigid plate is disposed between an axial end surface of one of the front and rear housings and heads of the bolts. The front housing and the rear housing are connected by the bolts via the rigid plate.

What is claimed is:  
     
         1 . A compressor comprising, 
 a front housing;    a rear housing connected to the front housing;    a plurality of bolts connecting the front housing and the rear housing in an axial direction; and    a rigid plate disposed between an axial end surface of one of the front and rear housings and heads of said bolts; and    wherein the front housing and the rear housing are connected by said bolts via said rigid plate.    
     
     
         2 . The compressor according to  claim 1 , wherein said rigid plate is annular in shape, and said bolts are positioned on the circumference of said rigid plate.  
     
     
         3 . The compressor according to  claim 2 , wherein said rigid plate is annular in shape, and said bolts are positioned substantially in equiangular positions on the circumference of said rigid plate.  
     
     
         4 . The compressor according to  claim 2 , wherein said rigid plate is annular in shape, and said rigid plate is formed in one piece.  
     
     
         5 . The compressor according to  claim 2 , wherein said rigid plate is annular in shape, and said rigid plate is constituted of a plurality of plates, and each plate is screwed by a plurality of bolts.  
     
     
         6 . The compressor according to  claim 1 , wherein said rigid plate is disk-shaped, and said bolts are positioned on the circumference of said rigid plate.  
     
     
         7 . The compressor according to  claim 1 , wherein refrigerant gas used in the compressor is carbon dioxide.  
     
     
         8 . The compressor according to  claim 1 , wherein the compressor is a swash plate type.  
     
     
         9 . The compressor according to  claim 1 , wherein the compressor is a variable displacement type.
