Abstract
In a variable displacement vane-type rotary compressor, a rotational displacement of an adjust member relative to a front member fixedly closing a front end of a cam ring varies a compression starting point of a rotary vane in a working chamber formed in the cam ring. The front member is formed with an induction port and a bypass port, and the adjust member is formed with a bypass recess. The induction port and the bypass recess are in communication with each other in the working chamber irrespective of a position of the vane under all of the rotational displacement of the adjust plate to establish a communication between the induction port and the bypass port in the working chamber irrespective of the position of the vane when the bypass port overlaps with the bypass recess.
