Abstract:
A swash plate type variable displacement compressor comprising:a housing formed by a cylinder block, a front housing, and a rear housing; a drive shaft rotatably supported by the housing; a swash plate operatively connected to the drive shaft, the swash plate integrally rotatable with the drive shaft and tiltable relative to the drive shaft; a piston engaging with the swash plate through a pair of shoes; wherein rotation of the drive shaft is converted to reciprocation of the piston through the swash plate and the shoes, and the displacement of the compressor is adjusted by varying the inclination angle of the swash plate with respect to a plane perpendicular to the axis of the drive shaft; and wherein the swash plate includes a base member made of copper series and a sliding layer coating a sliding surface of the base member with respect to the shoes.
