量形ポンプの馬力制御装置。 The force of a horsepower setting spring whose deflection is adjusted by an adjusting screw and a control spring supported by the control piston act in one direction on the displacement control piston that controls the displacement of a variable displacement pump, and in the opposite direction. In a system that controls the horsepower of the pump at a constant level by guiding the discharge pressure of the pump through a servo piston on which the force of the pressing piston that receives the discharge pressure of the pump acts, the horsepower setting spring has a A horsepower control device for a variable displacement pump, which is provided by connecting an electromagnetic magnet to further adjust the deflection displacement given by the adjustment screw.
