ABSTRACT:
A swash plate type variable capacity compressor having rotary valves 16 and 17 that rotate together on a rotating shaft 1. The rotary valves 16 and 17 are arranged on the shaft 1 in such a manner that, upon one complete rotation, the rotary valves 16 and 17 are connected, in sequential manner, for respective rotating angles, with circumferentially spaced piston chambers Sp and Sp' via respective intake passageways on the rotary valves 16 and 17. The arrangement of the intake passageway Pr and Pr' is such that the value of the rotating angle in a communication between the intake passageways Pr and Pr' and the piston chamber changes in accordance with the axial position of the rotary valves 16 and 17 on the shaft 1. Control of the rotating angle can vary the effective volume of the piston chambers Sp and Sp', thereby continuously varying the compressor capacity.
