Compressor

Abstract

A compressor includes a housing, a cylinder block, a valve plate, a discharge valve forming plate and a retainer gasket. The discharge valve forming plate includes a discharge valve, a connecting portion and a discharge valve engaging portion. The discharge valve opens and closes the discharge port. A plurality of discharge valve support portions extends from the connecting portion to support the discharge valve. The discharge valve engaging portion extends from the connecting portion. The retainer gasket includes a retainer, a gasket and a retainer gasket engaging portion. The retainer restricts an opening and closing operation of the discharge valve. The gasket ensures airtightness between the housing and the cylinder block. The retainer gasket engaging portion is formed by bending a part of the retainer gasket. The discharge valve forming plate and the retainer gasket are positioned by connecting the discharge valve engaging portion and the retainer gasket engaging portion.

What is claimed is: 
     
         1 . A compressor comprising:
 a housing in which a suction chamber and a discharge chamber are formed;   a cylinder block in which a compression chamber is formed; and   a valve plate including a discharge port through which the discharge chamber and the compression chamber communicate with each other;   a discharge valve forming plate having a flat plate shape, the discharge valve forming plate including:
 a discharge valve configured to open and close the discharge port; 
 a connecting portion from which a plurality of discharge valve support portions extends to support the discharge valve; and 
 a discharge valve engaging portion extending from the connecting portion; and 
   a retainer gasket including:
 a retainer configured to restrict an opening and closing operation of the discharge valve; 
 a gasket configured to ensure airtightness between the housing and the cylinder block; and 
 a retainer gasket engaging portion formed by bending a part of the retainer gasket, 
   wherein the discharge valve forming plate and the retainer gasket are positioned by connecting the discharge valve engaging portion and the retainer gasket engaging portion.   
     
     
         2 . The compressor according to  claim 1 , wherein the retainer gasket engaging portion is a pair of projections and the discharge valve engaging portion is a projection inserted between a pair of the projections. 
     
     
         3 . The compressor according to  claim 2 , wherein the retainer gasket engaging portion includes an engaging portion engaged with the discharge valve engaging portion to prevent the discharge valve forming plate from falling off. 
     
     
         4 . The compressor according to  claim 3 , wherein the compression chamber and the discharge chamber are partitioned by a partitioning wall, the partitioning wall is a valve plate provided between the cylinder block and the retainer gasket, and an accommodating portion is formed in the valve plate and accommodates the projection of the retainer gasket engaging portion. 
     
     
         5 . The compressor according to  claim 3 , wherein the cylinder block and the partition wall are integrally formed, and an accommodating portion is formed in the cylinder block and accommodates the projection of the retainer gasket engaging portion. 
     
     
         6 . The compressor according to  claim 4 , wherein an accommodating and engaging portion is formed in the accommodating portion and the accommodating and engaging portion is engaged with the projection of the retainer gasket engaging portion to perform positioning. 
     
     
         7 . The compressor according to  claim 5 , wherein an accommodating and engaging portion is formed in the accommodating portion and the accommodating and engaging portion is engaged with the projection of the retainer gasket engaging portion to perform positioning.
