ルブ。[Claim for Utility Model Registration] A spool is provided in an internally hollow valve body so as to be able to reciprocate, and by movement of the spool, a valve chamber provided on the outer periphery of the spool can be selectively connected to an inlet and an inlet provided in the valve body. The spool valve is provided with a passage passing through the spool in the axial direction and a through hole that communicates the passage with the valve chamber. A spool valve, characterized in that a plurality of spool valves are provided, and the arrangement is such that there is no directionality relative to the inlet and outlet of the valve body.
