A VARIABLE DISPLACEMENT SWASH PLATE TYPE COMPRESSOR

摘要

PURPOSE: A variable capacity swash plate type compressor is provided to prevent the leakage of the working fluid and the increasing noise by providing oil with a valve assembly through a suction chamber. CONSTITUTION: A variable capacity swash plate type comprises a cylinder block, a front housing, a rear housing, a rotary shaft(100), and a rotor(160). The cylinder block has a plurality of cylinder bores. The front housing is coupled with the front of cylinder block and forms the crank-case in between. The rear housing is coupled with the rear part of the cylinder block and forms the suction chamber and ejection chamber in between them. The rotary shaft passes through the center of front housing and cylinder block, and is rotatably supported. The rotor is coupled with the rotary shaft and is rotated integrally. The rotary shaft forms a communicating passage(110) and an oil separation passage(120) in inside. The oil separation passage couples the outer portion of the rotor and the communicating passage. The oil supply means in which the oil can flow along the communicating passage is formed in the adjacent part with the rotary shaft.
