行う位置関係にあるスプール弁。 A valve body having a sliding hole formed therein and having at least a first oil port, a second oil port, and a third oil port opened in the sliding hole, a spool slidably inserted into the sliding hole, and a spool inserted into the sliding hole. The spool is composed of an actuating means for displacing in the axial direction, and the spool has a sub-land portion with a narrow land width divided in the axial direction via an annular groove on the side that communicates with the first oil port and the second oil port. A land portion is formed, and when the spool is displaced, the land portion connects the second oil port and the third oil port.
A spool valve that cuts off the communication relationship with the oil port, and the sub land portion is positioned to open or cut off the communication relationship between the first oil port and the second oil port.
