PURPOSE:To enable to carry out operation control easily, by a method wherein the titled valve is so constituted that a throttle part is made to form at the time of an opening and closing operation through the movement of a spool, a part of a flow of a fluid flows out at the throttle part is directed so as to generate thrust force for opening action through a notch, and operation force and a quantity of the movement of the spool are made into proportional relation. CONSTITUTION:At the time of opening operation due to leftward movement of a spool 12, a pair of notches 14 whose one edge is opened in opposition to a throttle part 13 is provided on a predetermined part of the spool positioning close to the throttle part 13. As a liquid flow of a liquid flowing through a notch 14 possesses component force in an axial direction and the direction coincides with a direction of opening operation of the spool 12, operation force and a quantity of movement of the spool are made into proportional relation. |
