Abstract
Provided is a variable displacement compressor that is directed to cost reduction and productivity enhancement of a second control valve that adjusts an opening degree of a discharge passage for discharging a refrigerant in a controlled pressure chamber to a suction chamber. The variable displacement compressor includes the second control valve () configured to decrease an opening degree of the discharge passage to a minimum value when a first end surface () of a valve body () accommodated in a valve chamber () comes into contact with a first end wall surface () of the valve chamber () to close a second port () and a third port (), and configured to increase the opening degree of the discharge passage to a maximum value when the first end surface () of the valve body () separates from the first end wall surface () of the valve chamber () to open the second port () and the third port (). The valve body () is supported movably in a direction perpendicular to the first end wall surface () without contact with a peripheral wall surface () of the valve chamber (), by a guide shaft portion () being slidably inserted into a receiving portion () formed at a radially center portion of the valve body ().
