A swash plate type compressor comprising:
- a housing including a cylinder block;
- a swash plate rotatably mounted in said housing and supported by a rotatable drive shaft, said swash plate having a first substantially flat surface and a second substantially flat surface;
- at least one piston disposed in the cylinder block, said piston including a pair of spaced apart pockets formed therein;
- and
- at least one shoe having a first portion and a second portion, the first portion having a first surface slidably engaging one of the first surface and the second surface of said swash plate and a second surface adapted to be received by the second portion, the second portion having a first surface adapted to receive the second surface of the first portion and a second surface received in one of the pockets of said piston, said shoe facilitating a slanting of said swash plate and a transfer of rotation of said swash plate to a reciprocating motion of said piston, at least the first portion of said shoe being formed from a copper alloy.
