油圧パイロット切換弁。The spool of the hydraulic pilot switching valve is configured to be switched by the force of a spring acting on one end and the force due to fluid pressure acting on the other end, and the fluid pressure on the other end of the spool acts. A piston having a larger pressure-receiving area than the spool and having a protrusion that abuts on the other end is housed in the chamber, and a weak spring is provided that makes the piston on the opposite side abut the spool in the chamber where the protrusion exists. The piston is divided into two chambers, a first flow path that always guides the fluid pressure to a chamber provided with a weak spring, and a first flow path that always leads the fluid pressure to a chamber provided with a weak spring, and a first flow path that leads the fluid pressure to the chamber where the protrusion exists before the spool is switched. A hydraulic pilot switching valve in which pressure is guided, but after the switching operation, tank pressure is guided into the chamber where the protrusion exists (forming a second flow path).
