ABSTRACT:
A pressure control valve includes a valve portion disposed in a passage from a refrigerant radiator to a suction port of a refrigerant compressor in a vapor-compression refrigerant cycle system. The valve portion controls a refrigerant pressure at an outlet of the refrigerant radiator in accordance with a refrigerant temperature at the outlet of the refrigerant radiator, and the valve portion has a control pressure characteristic in which a pressure change relative to a temperature is smaller than that of the refrigerant. Furthermore, the valve portion may have a fluid passage through which refrigerant flows even when a valve port of the valve portion is closed by a valve body. Accordingly, when the refrigerant radiator is used for heating a fluid, heating capacity for heating the fluid can be rapidly increased at a heating start time.
