    摘要: A rotary pilot valve in which a force required to operate the pilot valve is reduced and especially the pilot valve can be operated with a very small operating force as in a fingertip type, and the number of parts forming the pilot valve is reduced. In a body, a tank port, a pair of pump ports, a first output port, and a second output port are formed. In a cylindrical valve, a pair of notch grooves is formed and connected with each other by a balance hole. Variable throttles are formed on a side of the tank port and a side of the pump port of the notch groove. An open area of one of the variable throttles gradually increases while an open area of the other gradually reduces by tilting of an operating lever. Pressure oil lead into the notch groove through the variable throttle is output from the first output port as an intermediate throttle pressure.
