By opening and closing the pilot hole with a solenoid valve, the pressure in the pressure regulating chamber changes and the pressure-operated valve is displaced, causing a gap between the high-pressure side pipe and the low-pressure side pipe. In a pilot-type solenoid valve that can be opened and closed, a plurality of fine holes each having an opening area smaller than the leak hole and having a total opening area larger than the leak hole are provided between the leak hole and the high-pressure side pipe. A pilot type solenoid valve characterized by communication.
