Patent Searching and Data


Document Type and Number:
Japanese Patent JPH0214996
Kind Code:
B2
Abstract:
A reciprocating piston type refrigerant compressor is disclosed includes a compressor housing having a cylinder block provided with a plurality of cylinders and a crank chamber adjacent the cylinder block. A piston slides within each cylinders and is reciprocated by a wobble plate driven by a cam rotor means. A drive shaft is connected to the cam rotor means to drive the cam rotor. The cam rotor means includes a slopping surface to closely proximity to the wobble plate which is changable of slant angle, i.e., stroke of the piston within the cylinder can be changed by the change of the slant angle of slopping surface. The slant angle of slopping surface is changed in coupliance with the change of the pressure in the crank chamber. The crank chamber is communicated with a suction chamber through passage way, and valve control means is controlled the opening and closing of the passage way. Whereby the capacity of the compressor is controlled by change of slant angle of slopping surface.
