摘要：
The displacement control valve 11, 11a for controlling a short time period of compressor displacement comprises a differential pressure sensing section and a separate valve section. Differential pressure is sensed by a small-diameter piston rod 23 such that a small-sized solenoid section suffices to control the differential pressure. A valve element 26 of larger diameter than the piston rod 23, when opened controls an increased flow rate of refrigerant, and is integral to a shaft 32. The pressure Pc from a pressure-regulating chamber is received at axial opposite ends of a reduced-diameter portion of the shaft 32. The suction pressure Ps from a suction chamber is received at axial opposite ends of the valve element 26 and the shaft 32, to balance influences of the pressures Pc, Ps such that the travel of the valve element 26 is controlled only by the differential pressure between Pd and Pc as sensed by the piston rod 23.
