Abstract
PURPOSE:To make discharge displacement accurately variable, by providing a switch valve disc for an interconnection passage on the wat to a compression stroke in a cylinder so as to lead lubricating oil in an oil separator, simultaneously with providing a suboil reservoir chamber capable of separating refrigerant from lubricating oil. CONSTITUTION:Refrigerant entered from an inlet port 14a, via a suction chamber 5, is sucked into a cylinder chamber R being made up of a rotor 2 and housing side plates 6 and 7 and discharged outside after passing through an oil separator 16a where it is compressed. When the capacity of a compressor comes to being more excessive that the initial demand, a solenoid coil 35a is unenergized and a valve disc 34a moves upward, disconnecting the interconnection of passages 30a and 20b so that the pressure of lubricating oil which so far pushed a valve 22 from backside goes out whereby the valve disc 22 moves to the left and refrigerant on the way to the compression stroke is taken back in the suction chamber past a partial clearance A. The discharge is thus decreased.
