WIPO Patent Application WO/2015/141245
Kind Code:
A1
Abstract:
Provided is a control valve with which the length of a device in the axial direction can be reduced as much as possible in order to improve the ease of installation inside the engine room. An electromagnetic selector valve (21) is equipped with: a valve body (50), which is a cam bolt for connecting a vane rotor (9) to one end (2a) of a camshaft (2); a sleeve (51) which is inserted in the valve body and fixed to the inner peripheral surface thereof; and a spool valve body (52) which is housed inside the sleeve so as to be slidable in the axial direction and switches the supply and discharge of a hydraulic oil to and from a retard hydraulic chamber (11) and an advance hydraulic chamber (12). A male screw part (50f) to be screwed to a female screw part (2c) is formed on the outer peripheral surface of the valve body, said female screw part being formed in a bolt hole (2b) which is disposed in the axial direction inside of one end of the camshaft, and the formation position of the male screw part (50f) and the position of the spool valve body are arranged so as to overlap with each other in the axial direction of the valve body.
