特徴とするリリーフバルブ。 The relief valve is disposed between a high-pressure side oil passage port and a low-pressure side oil passage port, and a plunger slides against a spring bias due to a pressure increase in the high-pressure side oil passage port, thereby communicating the two ports. A reaction spring chamber for spring-biasing the plunger is disposed below the low-pressure oil passage port, and an oil passage is provided for communicating the reaction spring chamber with the low-pressure oil passage port when the plunger is raised. A relief valve characterized by:
