Abstract: A slant plate type compressor with a variable displacement mechanism is disclosed. The compressor includes a compressor housing having a cylinder block provided with a plurality of cylinders and a crank chamber. A piston is slidably fitted within each of the cylinders and is reciprocated by a drive mechanism. The drive mechanism includes a drive shaft rotatably supported by the compressor housing, a cam rotor fixed on the drive shaft, and a slant plate having a surface with an adjustable incline angle. The incline angle is varied in accordance with the pressure in the crank chamber. A wobble plate is disposed adjacent the slant plate to convert the rotating motion of the drive shaft, the rotor, and the slant plate into the reciprocating motion of the pistons which are coupled to the wobble plate through corresponding connecting rods. A hinged joint mechanism hingedly connects an arm portion of the slant plate to an arm portion of the rotor to permit variations in the incline angle of the slant plate. An abrasion preventing mechanism formed of a metal is disposed between the arm portion of the cam rotor and the arm portion of the slant plate to effectively reduce abnormal abrasion on the frictional surface of the arm portion of the rotor.
