ABSTRACT:
A refrigerant compressor having pistons reciprocated in respective cylinders through piston rods by a wobble plate driven by a wedge-shaped rotor which is secured on a drive shaft, which compressor has a structure which is dynamically balanced so that reduced vibration of the compressor may occur in the operation thereof. The wobble plate and the wedge-shaped rotor are, respectively and/or in combination, so formed that all of the centrifugal forces developed on the plate and the rotor cancel out one another in radial directions, and the torques on the wobble plate and the rotor developed due to the centrifugal forces cancel torques provided on the wobble plate due to inertia of the wobble plate, pistons and piston rods which are reciprocated.
