発器出口圧力制御用弁機構。 A valve mechanism disposed in a suction pipe connecting an evaporator and a compressor, the valve mechanism having a refrigerant disposed in the main body so as to apply the pressure of the suction pipe upstream of the valve mechanism to its head side. A spool valve for flow rate adjustment, a pressure chamber that applies control pressure to the bottom side of the spool valve, and a downstream suction line of the valve mechanism and a discharge line of the compressor are selected based on the set pressure at the evaporator outlet. and a switching valve means which communicates with the pressure chamber.
