機。 An on-off valve mechanism installed in a passage that communicates the suction chamber and a high-pressure chamber into which high pressure is introduced changes the discharge capacity by opening and closing the passage in response to changes in suction pressure according to heat load. In the controllable variable displacement compressor, the auxiliary low pressure chamber in which the pressure responsive part of the on-off valve mechanism is arranged and the suction chamber are separated by a partition wall, and a communication hole is provided in the partition wall to communicate the two chambers. A variable displacement compressor, characterized in that the communication hole is provided with a throttling amount changing means for increasing the opening area of the communication hole in accordance with an increase in the pressure difference between the two chambers.
