回路。In a variable displacement pump in which a pilot oil passage branched from the discharge side oil passage of the variable displacement pump is connected to an output controller to detect fluctuations in discharge pressure and control the discharge volume, a throttle valve is connected to the discharge side oil passage. The pressure difference between the front stage and the rear stage of the valve is input to the output controller directly through a pilot oil path or indirectly through a servo motor or the like to control the discharge capacity. output control circuit for a variable displacement pump.
