ABSTRACT:
A fluid control valve device includes a sleeve, a rotor, and a first recess groove. The sleeve has an inner circumferential surface in which two types of axial channel grooves communicating with an input port and a return port are formed in the circumferential direction, and left and right output ports are open in land portions between the channel grooves. The rotor is inserted in the inner circumferential surface of the sleeve so as to be rotatably held relative to the sleeve and has an outer circumferential surface in which channel grooves communicating with the axial channel grooves of the sleeve are formed in the circumferential direction at positions opposite to the land portions in which the output ports of the sleeve are open, and first and second land portions are formed at positions opposite to the channel grooves of the sleeve. The first recess groove is formed in the first land portion of the rotor to oppose a fluid supply hole communicating with the input port and open in the channel groove of the sleeve.
