Component having slide contact area of compressor

Abstract

Lubricating films are formed on end surfaces of a swash plate, respectively. The lubricating films make slide contact with shoes, respectively. The lubricating films are made of a copper based material which contains bismuth but does not contain lead. A good slide contact characteristic may be obtained while restricting the amount of lead to be used.

1 . A component of a compressor, said component including a lubricating surface portion in a slide contact area, the lubricating surface portion being formed of a copper based material containing bismuth.  
     
     
         2 . The component according to  claim 1 , wherein said copper based material comprises copper-tin based alloy.  
     
     
         3 . The component according to  claim 1 , wherein said copper based material does not contain lead.  
     
     
         4 . The component according to  claim 1 , wherein a lubricating film made of a copper based material containing bismuth is provided in said slide contact area to form said lubricating surface portion.  
     
     
         5 . The component according to  claim 4 , wherein said lubricating film is made on a base material by sintering.  
     
     
         6 . The component according to  claim 1 , wherein said compressor comprises a swash plate type compressor having a swash plate rotatable with a rotating shaft, a piston, and a shoe disposed between the swash plate and the piston so as to make slide contact with said swash plate and said piston, whereby a rotational motion of said swash plate is transferred to said piston via said shoe to reciprocatingly move said piston, and said component is said swash plate, in which said swash plate has lubricating surface and said shoe has a lubricating surface to make slide contact with the lubricating surface of said swash plate.
