Abstract
A swash plate compressor includes a housing that has a cylinder bore and rotatably supports a drive shaft. A swash plate is operatively coupled to the drive shaft for rotation therewith. A piston is accommodated in the cylinder bore for reciprocating movement. First and second spaced shoes are fitted to the piston on a side adjacent to the cylinder bore and on a side away from the cylinder bore, respectively, for coupling the piston to the swash plate. The rolling body is mounted on the swash plate through a bearing and in slide contact with the first shoe. A surface of the rolling body in slide contact with the first shoe or a surface of the first shoe in slide contact with the rolling body has a diamond-like carbon film. A surface of the rolling body in rolling contact with the bearing exposes a base material of the rolling body.
