Claims

[Scope of utility model registration request]

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 an angle control motor, and the body is constructed by stacking an arbitrary number of manifold elements, and each manifold element has a plurality of pairs of one-to-one port holes corresponding to a plurality of actuators. and a tank port communicating with the tank is formed, and the selector has the same number of pressure ports communicating with the hydraulic pump corresponding to the manifold elements and communicating with the tank port. A flow path is formed to
By rotating the angle control motor by a predetermined angle, the body or selector is rotated by a predetermined angle, and any manifold element among the above arbitrary number of manifold elements and any one of the plurality of port holes is rotated. By connecting one port hole to any pressure port of the selector and the other port hole to the tank port via a flow path, driving oil is supplied only to the desired actuator to perform the specified operation. A hydraulic control device characterized in that the hydraulic control device is configured to be able to
