ABSTRACT:
This invention is directed to a wobble plate type refrigerant compressor. The compressor includes a housing having a cylinder block provided with a plurality of peripherally located cylinders, a front end plate and a crank chamber enclosed by the front end plate and the cylinder block. A piston is slidably fitted within each of the cylinders. A drive shaft is connected to a rotor which is connected to a slant plate. A wobble plate is disposed on an inclined surface of the slant plate. A connecting rod connects the wobble plate within each of pistons. Each end of the connecting rod is coupled to the wobble plate and the piston by a ball-and-socket joint, respectively. The ball-and-socket joints provided at the wobble plate are peripherally located. A rotation preventing device for preventing rotation of the wobble plate includes a fork-shaped slider attached to an outer peripheral end of the wobble plate and a sliding rail held between the cylinder block and the front end plate. The center of the ball-and-socket joints provided at the wobble plate are radially shifted in the rotational direction of the cam rotor with respect to the center of ball-and-socket joints provided at each of the pistons by a predetermined angle; thereby preventing a cyclic collision between the fork-shaped slider and the sliding rail when the cam rotor rotates.
