連通路を介して連通させた電磁切換弁。 A pump port and a pair of actuator ports are formed in the valve body, and a spool is installed inside the valve body, and first to third annular grooves are formed in the spool, and the first annular groove is always connected to the pump port. communicate with the second or third
One of the annular grooves is always communicated with the tank, and the second and third annular grooves are communicated via a circulation passage formed in the spool, and a solenoid is provided at both ends of the spool, and the push rod of this solenoid is connected to the spool. At the same time, the chambers on both sides of the spool in contact with these push rods are communicated with each other, and depending on the switching position of the spool, the first annular groove and either one of the actuator ports are connected to each other. In an electromagnetic switching valve configured to control the amount of wrap and the amount of wrap between the second and third annular grooves and the other actuator port, the chambers on both sides of the spool are connected via a communication path separate from the circulation path. A connected solenoid switching valve.
