Abstract

The present invention provides a spool valve capable of switching a plurality of oil passages and keeping the length dimension of a spool in the axial direction (sliding direction) short. The spool valve has: the first oil passage (21) with the first to third ports (A1~A3) opened in the spool hole (10); the first oil passage (21) with the fourth to sixth ports (B1~B3) The second oil passage (22); the first to fourth oil grooves (31-34) arranged in the circumferential direction at the same position in the axial direction of the outer peripheral surface (30c) of the spool (30); on the spool (30) through the first communication passage (36) from the first oil groove (31) to the third oil groove (33); and in the spool (30) from the second oil groove (32) to the fourth oil groove (34) ), the spool valve is composed of: the spool (30) slides in the spool hole (10), so that the second orifice (A2) and the third orifice (A3) and the first 3. Switching of the communication of the oil tank (33) and switching of the communication between the 5th orifice (B2) and the 6th orifice (B3) and the 4th oil tank (34).

Description

technical field [0001] The present invention relates to a spool valve having a valve core, wherein the valve core is inserted into a valve core hole of a valve box in a freely sliding manner. Background technique [0002] There is a spool valve in which a valve body is slidably arranged in a valve body hole of a valve box. A spool valve having such a structure has been conventionally used for various applications such as a pressure control valve and a flow control valve. Such a conventionally known spool valve includes a valve box having a substantially cylindrical valve body hole, a substantially cylindrical valve body inserted into the valve body hole, and a spring that biases the valve body in the valve body hole. The spring is arranged on one end side of the valve body in the valve body hole, and urges the valve body toward the other end side in the axial direction. In addition, an oil passage having a plurality of orifices opened on the inner peripheral side surface o...
