とする油圧制御装置。 It consists of an angle control motor and a multi-position valve connected to the angle control motor, and the multi-position valve includes a body and a selector that are arranged in contact with each other, and one of the body and the selector is connected to the angle control motor. The body is connected to a motor and rotated by a predetermined angle by an angle control motor, and the body is formed with a plurality of one-to-one pairs of port holes corresponding to a plurality of actuators, and one tank port communicating with the tank. On the other hand, the selector is formed with one pressure port communicating with the hydraulic pump and a flow path communicating with the tank port, and the angle control motor is controlled by a predetermined angle. By rotating the body or selector by a predetermined angle, any one of the plurality of port holes in the body communicates with the pressure port of the selector, and the other port holes communicate with the pressure port of the selector through a flow path. By communicating with the tank port, driving oil is supplied to only the desired actuator to perform a predetermined operation, and the rotational position of the body or selector is detected by an external position detection means, and the desired correct rotational position is detected. A hydraulic control device characterized in that it is determined whether a body or a selector is accurately positioned relative to the body or the selector.
