Abstract
PURPOSE: To prevent abrupt change in pressure and rate of flow at the time of valve switching by designing the groove or port of a conical rotary valve to be used as a control valve for a power steering device in a straight tapered form or by providing a chamfer inclined with respect to the conical surface.
CONSTITUTION: A land 20 and a groove 21 are provided at the outside conical surface of a valve rotor 14, where the bottom of this groove 21 shall be in parallel with the rotary shaft and the sides of the groove shall be tapered as directed oppositely to the cone's face. At the inner surface of a valve sleeve 15 is provided a port 23, whose bottom shall be approx. in parallel with the axis and sides shall be tapered in the same direction as the cone's face. According to this constitution, when the valve is switched over by rotating the valve rotor 14, the communicating area between the groove 21 and port 23 changes extremely slowly with respect to unit rotation angle, so that mild change of the pressure and rate of flow can be obtained. Further, the valve rotor as well as valve sleeve can be molded in a single body.
