バルブ。A working fluid passage bent in an L shape is formed in the valve body, a working fluid intake port is formed at the upstream end of the working fluid passage, and a valve seat facing upstream is formed at the bent part in the working fluid passage. and a plunger that can come into contact with and separate from the valve seat, and when the plunger comes into contact with the valve seat, a part of the front surface of the plunger is connected to the working fluid path on the upstream side of the valve seat. A plurality of working fluid outlets are formed in the valve body downstream of the valve seat and communicate with the working fluid path, and one of the working fluid outlets is switched. The pilot valve is characterized in that the plunger communicates with the rear side of the plunger via a valve, and the plunger has a rear pressure receiving area larger than a front pressure receiving area.
