を特徴とする残圧開放機構付切換弁。A switching device comprising a base having a fluid supply port, two output ports, and two discharge ports, and a valve body that switches the direction of fluid flow between the ports by a valve body driven by an appropriate operating means. In the valve, a supply communication hole, first and second output communication holes, and first and second discharge communication holes are provided between the base and the valve body and communicate with the supply port, the output port, and the discharge port, respectively. A spacer with a spacer is attached, a spoon is movably inserted into a sliding hole provided in the spacer, and a first residual pressure release is made at one end of the spool to communicate a first output communication hole with the atmosphere. A piston equipped with a poppet valve element for opening and closing the passage hole is attached, and a poppet valve for opening and closing a second residual pressure release passage that communicates the second output communication hole with the atmosphere is attached to the other end of the spool. A residual pressure release mechanism characterized in that a pressure receiving chamber defined by a piston is communicated with the supply communication hole, and the spool is urged by a return spring in the direction of opening the residual pressure release hole. With switching valve.
