徴とする蒸発圧力制御弁。The pilot valve is displaced according to the pressure inside the evaporator, and the main valve is moved by the pressure in the auxiliary chamber, which is determined by the opening degree of the pilot valve, to adjust the opening degree of the refrigerant passage at the evaporator outlet, thereby increasing the evaporation pressure. In the evaporation pressure control valve, a space is formed between the main valve and a seat surface of a cylinder facing the main valve when the main valve is at a predetermined position, and the space is The evaporation pressure control valve is characterized in that when the main valve moves in the valve opening direction by a predetermined amount or more, the evaporation pressure control valve communicates with the auxiliary chamber.
