油圧回路。 In a hydraulic circuit for an industrial vehicle, the hydraulic circuit includes a pump driven by an engine that supplies hydraulic oil to hydraulic equipment, and a control valve that adjusts the amount of hydraulic oil supplied to the hydraulic equipment in accordance with the amount of operation of a control lever.
A transmission is provided between the engine and the pump, and a hydraulic oil supply passage switch is provided between the pump and the control valve, and a hydraulic oil supply passage opening/closing signal of the hydraulic equipment is transmitted to the hydraulic oil supply passage depending on the presence or absence of an operation amount. The transmission outputs a necessary and sufficient gear ratio signal to the switch, extracts the amount of hydraulic oil Q necessary for the hydraulic equipment based on the manipulated variable, detects the engine rotation speed, and supplies the amount Q of hydraulic oil to the transmission. A hydraulic circuit for an industrial vehicle, characterized in that it is provided with a controller that outputs output to the hydraulic circuit.
