Claims

[Claims for Utility Model Registration] (1) A control member rotatably provided in the compressor body and having a recess for a suction port on one side and a pressure receiving portion on the other side; A seal member is fitted into a seal groove formed on the periphery of the pressure receiving part, and this control member is rotated forward and backward according to changes in suction pressure, thereby changing the timing at which fluid compression starts and varying the discharge volume. A variable displacement compressor that can be controlled, characterized in that a communication groove is provided on the outer periphery of the control member to communicate the seal groove and the recess. (2) A control member is rotatably provided in the compressor body and has a recess for a suction port on one side and a pressure receiving part on the other side, and a control member is provided on the inner and outer peripheries of the control member and on the periphery of the pressure receiving part. A variable capacity compressor that can variably control the discharge volume by changing the timing at which fluid compression starts by fitting a seal member into the seal groove and rotating the control member forward or backward according to changes in suction pressure. A variable capacity compressor according to the present invention, wherein the seal member is provided with a communication groove that communicates the seal groove and the recess.
