用油圧回路。 In a hydraulic steering control device consisting of a steering valve that supplies pressure oil to a steering cylinder and a transmitter that operates the steering valve, there is provided a detection means for detecting a signal from the transmitter, and a signal obtained by the detection means. An on-off valve that opens a pipeline from a hydraulic power source only when it acts on a receiver, and an engine governor lever that operates when pressure oil continues to be supplied through the on-off valve to drive a hydraulic pump for a hydraulic steering control device. The engine is characterized by a control cylinder that rotates directly or indirectly to increase the engine speed until the desired value is reached, and returns to the state before operation when the supply of pressure oil is stopped. Hydraulic circuit for steering control.
