ル弁。 It consists of a valve housing and a valve stem inserted into the valve housing so as to be slidable in the axial direction.A valve seat is provided on the inner wall of the valve housing and is located between an input port and an output port, An annular elastic valve body fitted in the groove is formed so that its radial length is larger than its axial thickness, and this valve body is slid against the valve seat in the valve housing from the output port side. In a spool valve that opens and closes both ports in contact with each other, the valve body is formed in a bent state within the outer circumferential groove of the valve stem by providing a recess on the side opposite to the input port. A spool valve characterized in that a foot portion is provided at the end portion on the side surface side of the portion close to the sealing surface, the foot portion being able to come into contact with the opposite side surface of the outer circumferential groove of the valve stem.
