Abstract
A swash plate type compressor for compressing a refrigerant of an air conditioning system incorporating therein a rotating swash plate made of an aluminum alloy, one or more compressor pistons reciprocating in a cylinder block for effecting compression of the refrigerant, and an operative engagement means which is between the swash plate and the piston or pistons. The operative engagement means is made of a carbon steel material and a flattened face of the operative engagement means contacting the aluminum alloy swash plate consisting of a cementation treatment layer formed in the carbon steel material of the operative engagement means.
Claims5
A swash plate type compressor comprising:
- a cylinder block having therein at least one cylinder bore;
- a compressor piston reciprocally fitted in said cylinder bore for effecting compression of a refrigerant;
- a drive shaft axially passing through said cylinder block and rotatably supported by bearing means;
- a swash plate secured onto said drive shaft rotated by said drive shaft thereby causing a reciprocal motion of said piston, and an operative engagement means for establishing an operative engagement between said swash plate and said compressor piston, said operative engagement being formed with a flattened face slidably contacting said swash plate, wherein said swash plate is made of a high silica aluminum alloy, and wherein said operative engagement means is made of a carbon steel material, and wherein said flattened face of said operative engagement means comprises a boron diffused steel layer formed in said carbon steel material of said operative engagement means.
