記載の電磁切換弁。[Claims for Utility Model Registration] 1. A spool is disposed in a valve chamber in a switching valve body so as to be slidable in the axial direction, and a pilot pressure supply path is provided from the valve chamber to one end of the switching valve body in the axial direction. In an electromagnetic switching valve equipped with a pair of electromagnetic pilot valves for switching the pilot pressure supplied to a chamber, a piston is connected to the end of the spool on the electromagnetic pilot valve side, and the piston is An electromagnetic switching valve characterized in that a single sliding piston sliding chamber is provided, the tip end side of the piston in the piston sliding chamber is a first pilot chamber, and the opposite side is a second pilot chamber. 2. A third pilot chamber facing the end surface of the spool opposite to the piston is provided in the switching valve main body, and the third pilot chamber and the second pilot chamber are connected through a communication passage provided in the spool. An electromagnetic switching valve according to claim 1 of the utility model registration claim, which is connected in communication.
