Abstract:
A capacity control valve (1) includes a valve main body (10) having a first communication passage (11), a second communication passage (12), a third communication passage (13), and a main valve seat (15a), a pressure-sensitive body (24), a valve element (20) having an intermediate communication passage (29), a main valve portion (21c), and a restrictor portion (25), and a solenoid (30) that drives a rod (36). The rod (36) is relatively moved with respect to the valve element (20) so as to control an opening degree of the restrictor portion (25). The capacity control valve is capable of efficiently discharging a liquid coolant irrespective of pressure of a suction chamber and improving control stability.
