とする滑り弁。 A valve seat provided with a plurality of ports, a main body to which an outer valve seat is attached, a sliding valve body housed within the main body and capable of sliding in contact with the valve seat, and a sliding valve body that slides into a cylinder chamber formed within the main body. a driving piston that is guided and engages with the sliding valve body to drive the sliding valve body back and forth; and a spring that is provided between the driving piston and the sliding valve body and presses the sliding valve body against the valve seat. In the slide valve, a lubrication groove extending circumferentially in at least one of the drive piston and the cylinder chamber is provided in a pressure receiving range between the drive piston and the cylinder chamber by the spring, with a slide valve body in between. A slide valve characterized in that at least one slide valve is formed on both sides.
