摘要： An improvement in a capacity control valve for use in a fluid compressor with a relatively high pressure HP and a relatively low pressure LP for changing the operational characteristics thereof by using the relatively high pressure HP taking into consideration that an increased pressure loss of the refrigerant as generated from an increased flow rate thereof and the thermal load on the car cooler would occasionally occur on the part of the relatively high pressure HP during the operation. Wherein a capacity control valve, of the type operative to take the intermediate pressure AP, for the control of a specific amount of compressed gas to be bypassed to the suction side of the fluid compressor, as a linear function of the relatively low pressure LP using a differential pressure between the relatively high pressure HP and the relatively low pressure LP of the fluid compressor, comprises an adjusting device adapted to adjust the intermediate pressure AP in such a manner that the relative low pressure LP is made lower as the relatively high pressure HP becomes higher, and the relatively low pressure LP is made higher as the relatively high pressure HP becomes lower.
