Gasket for compressor

Abstract

A gasket ( 10 ) used in a compressor in which a gas is force-fed, improve the sealability and contribute stored miniaturization of the compressor. The gasket ( 10 ) includes a raised portion ( 35 ) rising so as to surround a sealed portion. An end ( 43 ) of the raised portion ( 37 ) and a base surface ( 30 ) of the gasket ( 10 ) are not positioned on a single plane. In addition, the raised portion ( 35 ) is constituted with a flat surface ( 40 ) set at a height different from the height of the base surface ( 30 ) and an inclined surface ( 41 ) with a predetermined angle of inclination connecting the flat surface ( 40 ) with the base surface ( 30 ).

1 - 11 . (canceled)  
   
   
       12 . A gasket for a compressor, used in a compressor in which a fluid is force-fed and having a raised portion rising so as to surround a sealed portion, wherein: 
 an end of said raised portion toward an inner edge and a base surface of said gasket are not set on a single plane;    said raised portion includes a flat surface positioned at a point with a height differing from the height of said base surface and an inclined surface with a predetermined angle of inclination, which links said flat surface with said base surface; and    an outer edge of said flat surface does not have a shape similar to the shape of said inner edge.    
   
   
       13 . A gasket for a compressor according to  claim 12 , disposed between a cylinder block and a valve plate, wherein: 
 an inner edge of said flat surface of said raised portion surrounding a cylinder formed at said cylinder block is not circular.    
   
   
       14 . A gasket for a compressor according to  claim 12 , wherein: 
 said outer edge of said flat surface in the entirety thereof comes in contact with an intake valve and only a specific portion of said inner edge comes in contact with said intake valve.    
   
   
       15 . A gasket for a compressor according to  claim 14 , wherein: 
 said specific portion corresponds to a connecting base portion of a lead portion of said intake valve.    
   
   
       16 . A gasket for a compressor, used in a compressor in which a fluid is force-fed, having a raised portion rising so as to surround a sealed portion and disposed between a valve plate and a cylinder head, wherein: 
 an end of said raised portion toward an inner edge and a base surface of said gasket are not positioned on a single plane; and    said raised portion is disposed so as to seal at least a high/low pressure barrier wall and an atmospheric pressure barrier wall.    
   
   
       17 . A gasket for a compressor according to  claim 16 , wherein: 
 said inclined surface is disposed so as to come in contact with said high/low pressure barrier wall or said atmospheric pressure barrier wall.    
   
   
       18 . A gasket for a compressor according to  claim 16 , wherein: 
 a retainer portion for regulating an operation of a discharge valve is included.    
   
   
       19 . A gasket for a compressor according to  claim 17 , wherein: 
 a retainer portion for regulating an operation of a discharge valve is included.    
   
   
       20 . A gasket for a compressor according to  claim 12 , wherein: 
 in said compressor, carbon dioxide is force-fed.    
   
   
       21 . A gasket for a compressor according to  claim 13 , wherein: 
 in said compressor, carbon dioxide is force-fed.    
   
   
       22 . A gasket for a compressor according to  claim 14 , wherein: 
 in said compressor, carbon dioxide is force-fed.    
   
   
       23 . A gasket for a compressor according to  claim 15 , wherein: 
 in said compressor, carbon dioxide is force-fed.    
   
   
       24 . A gasket for a compressor according to  claim 16 , wherein: 
 in said compressor, carbon dioxide is force-fed.    
   
   
       25 . A gasket for a compressor according to  claim 17 , wherein: 
 in said compressor, carbon dioxide is force-fed.    
   
   
       26 . A gasket for a compressor according to  claim 18 , wherein: 
 in said compressor, carbon dioxide is force-fed.    
   
   
       27 . A gasket for a compressor according to  claim 19 , wherein: 
 in said compressor, carbon dioxide is force-fed.
