<p>A valve section 13 of a control valve controls the flow rate between a discharge chamber and a crankcase, based on the differential pressure between discharge pressure Pd and suction pressure Ps. A pressure-sensing section 12 is provided in a high-pressure port 18. When a pressure-sensing piston 19 having a pressure-receiving area larger than a valve element 23 is exposed to a rapid discharge pressure change, the differential pressure generated between the discharge pressure Pd and a pressure in a pressure-adjusting chamber 20 acts on the valve element 23 opposite to the valve-opening/closing direction, to temporarily retard the motion of the valve element 23 which opens or closes by the differential pressure (Pd-Ps). Even a high-sensitivity variable displacement compressor promptly restores without hunting to a predetermined discharge capacity.</p> |
