リリーフ弁。 Connecting the first port 12 side and the second port 13 side
The free piston 25 to be shut off is held in the shutoff position by a spring 30, and the pressure receiving chamber 28 that pushes the free piston 25 in the shutoff direction is connected to the first port 12 through the small hole 29.
A plurality of pores 29 are formed on the circumference of the outer peripheral portion of the free piston 25 from the recess 35 formed at the center of the free piston 25, and the pressure on the first port 12 side of the free piston 25 acts. A bidirectional operating relief valve characterized in that the area and the pressure receiving area on which the pressure on the second port 13 side acts are the same.
