圧モータの制御回路。 An upstream 1st speed control valve and a downstream 2nd speed control valve are connected to the first pump in a series circuit, and the second pump is connected to an upstream 2nd speed control valve and a downstream 1st speed control valve in a series circuit. A switching valve is provided between the upstream 1st and 2nd speed control valve and the downstream 1st and 2nd speed control valve and the first motor and the second motor, and this switching valve allows the upstream 1st and 2nd speed control valve to be Pressure oil from the control valves is combined and guided to the first motor, and pressure oil from the downstream 1st and 2nd speed control valves is combined and guided to the second motor.
The first state guided by the motor and the pressure oil from the upstream 1st and 2nd speed control valves are combined and guided to the second motor, and the pressure oil from the downstream 1st and 2nd speed control valves is combined. A control circuit for a hydraulic motor, characterized in that the control circuit is configured to be able to freely switch between a second state in which the first motor is guided.
