Abstract: PURPOSE:To decrease passage resistance in a bypass passage so as to perform efficient displacement control by connecting a compression chamber and a suction chamber through a bypass port while rotating a rotary valve and connecting a part of a suction passage, at the time of small displacement, to the bypass port. CONSTITUTION:A piston 40 is moved to a move end on the first chamber 43 side by hydraulic pressure and at the time of smallest displacement, the main suction passage 33 is throttled between the first suction port 30 and the second suction port 31 or between the second suction port 31 and the third suction port 32 and at the same time end position on the delivery port side of the first suction port 30 shifts to a position nearest to the delivery port.
