流量制御装置。 When the control valve that controls the actuator is held in the neutral position, the pilot pressure in the pilot passage is maintained at the set pressure, and the pilot pressure maintained at the set pressure is applied to the regulator to adjust the discharge amount of the variable discharge pump. In a flow rate control device for a variable discharge pump configured to reduce the flow rate, a high-pressure large-capacity relief valve and a low-pressure small-capacity relief valve are arranged to face each other within the valve body, and between the opposing parts of these two relief valves, the pressure in the pilot passage is A flow control device for a variable discharge pump equipped with a pressure chamber that introduces
