油圧回路。The drive motor and multiple other actuators are operated by one main pump, and a speed increase pump is provided separately from the main pump, and the speed increases according to the switching position of the speed increase solenoid valve connected to the speed increase pump. Therefore, in the hydraulic circuit of the self-propelled vehicle that merges the discharge oil of the speed increasing pump into the main pump, when at least two or more predetermined actuators among the plurality of actuators are operated simultaneously, A hydraulic circuit provided with a control mechanism for switching the speed increasing solenoid valve based on an operation signal to cause oil discharged from the speed increasing pump to join the main pump.
