Claims (1)
ーブの内部に沿い摺動しうるスプールとをそなえ、こ゛
のスプールの周りの弁室から該弁本体のドレンポートへ
向かう流路の途中に、上記スリーブの端面に沿う放射溝
形成部材により円板型絞り流路が形成されたスプール弁
において、上記円板型絞り流路で消費される圧力損失を
補うように、スリーブポートに溝を設けその開口面積を
増大したことを特徴とするスプール弁。A sleeve is fluid-tightly mounted inside the valve body, and a spool is slidable along the inside of the sleeve, and a flow path from the valve chamber around the spool to the drain port of the valve body is provided. In the spool valve in which a disc-shaped throttle channel is formed by a radial groove forming member along the end surface of the sleeve, a groove is formed in the sleeve port to compensate for the pressure loss consumed in the disc-shaped throttle channel. A spool valve characterized by having an increased opening area.
