。[Claims for Utility Model Registration] (1) A cylindrical sleeve with an inlet and an inlet on the side is fitted into a cylindrical housing with a bottom, and the opening of the sleeve toward the bottom of the housing is closed by a closing member. A pressure chamber is provided on the abutting surface of the housing and the sleeve, and a spool having a passage passing through the sleeve in the axial direction is reciprocably mounted, and the spool is reciprocated,
In the spool valve that opens and closes by selectively aligning a valve chamber formed on the outer periphery of the spool with an outflow inlet, a gap is formed between the closing body and the bottom surface of the housing, and the gap and the passage are communicated with the closing body. 1. A spool valve characterized in that a spool valve is provided with a slit for communicating between the gap and a pressure chamber on the outer peripheral surface of the sleeve. (2) A spool having a passage penetrating in the axial direction is reciprocably mounted in a cylindrical sleeve with an inlet and an inlet on the side, and a valve chamber is formed between the contact surfaces of the spool and the sleeve, A spool valve that opens and closes by reciprocating the spool to selectively align a valve chamber formed on the outer periphery of the spool with an outflow inlet, the spool having a groove on the outer circumferential surface of the spool that communicates the passage and the valve chamber. A spool valve characterized by the provision of a spool valve.
