ABSTRACT:
A reciprocating piston type refrigerant compressor includes a compressor housing having a cylinder block provided with a plurality of cylinders and crank chamber adjacent the cylinder block. A piston slides within each of cylinders and is reciprocated by a wobble plate driven by a cam rotor mounted on a drive shaft. The cam rotor comprises a rotor plate fixed on an inner terminal end of a drive shaft and slant plate with a sloping surface in close proximity to the wobble plate. The slant plate is hinged to the rotor plate for adjusting the slant angle thereof in response to change of pressure in the crank chamber. The pressure in the crank chamber is controlled by controlling communication between the crank chamber and the suction chamber. The wobble plate is supported for a nutational motion on a ball element which is disposed on supporting element slidably carried in the cylinder block to maintain the wobbling center thereof on the center of the ball element.
