タリバルブ。 A housing in which an inlet oil passage from the pump and an outlet oil passage to the tank are formed, a valve sleeve rotatably fitted in this housing, and a valve rotor fitted in this valve sleeve so that it can rotate relative to each other. In a power steering rotary valve that supplies and discharges pressurized fluid to the power cylinder by switching the flow path between the valve rotor and the valve sleeve through relative rotational displacement between the valve rotor and the valve sleeve, the rotary valve has an inlet oil inlet formed in the housing. Both the inlet and outlet oil passages are branched into two, and these two openings are connected to the pitch of the oil passage on the circumference of the valve sleeve.
A power steering rotary valve characterized by being placed at a position offset by an angle that is an odd multiple of the 1/2 angle.
