装置。[Claims for Utility Model Registration] (1) A rotor having two types of passage grooves in the circumferential direction that communicate with an inlet port and a return port, and a rotor that is fitted on the outer periphery of the rotor and selectively connected to each passage groove on the rotor side. A supply-side annular groove is provided on the outer periphery of the rotor and has a passage groove in the circumferential direction that communicates with the fluid and guides the fluid to the output port, and is connected to the input port-side passage groove of the rotor through a fluid supply hole that opens at a portion opposite to the passage groove. A rotary fluid control valve device comprising: a sleeve formed in the rotor; and a valve housing in which the rotor and the sleeve are disposed so as to be relatively rotationally displaceable therein, and the valve housing has the inlet port and the return port. The port hole of the entry port is inclined and connected to the supply side annular groove on the outer periphery of the sleeve,
A fluid control valve device characterized in that the center of the port is formed in the valve housing so as to face the fluid supply hole on the sleeve side. (2) A rotor that has two types of passage grooves in the circumferential direction that communicate with the inlet port and the return port, and a rotor that is fitted on the outer periphery of the rotor and selectively communicates with each passage groove on the rotor side to direct fluid to the output port. A supply side annular groove is formed on the outer circumferential portion of the rotor and has a passage groove in the circumferential direction and is connected to the inlet port side passage groove of the rotor through a fluid supply hole opening at a portion opposite thereto. A sleeve, in which a return side annular groove connected to a side return port side passage groove via a rotor internal space and a fluid discharge hole is formed on an outer peripheral portion offset from the supply side annular groove in the axial direction; In a rotary fluid control valve device comprising a valve housing in which a sleeve is disposed so as to be relatively rotationally displaceable, and a valve housing having the inlet port and the return port, an annular groove is inclined in an annular groove on the reflux side of the outer circumference of the sleeve. A fluid control valve device characterized in that a port hole of the return port connected to the valve housing is formed with the center of the port oriented toward the fluid discharge hole on the sleeve side.
