Study of a Novel Axial Piston Pump with Adjustable Tilting Piston

2019 IEEE 8th International Conference on Fluid Power and Mechatronics (FPM), 2019
In pump-control system, the flow rate is controlled by the rotating rate of pump or the displacement of the pump. The fixed displacement axial piston pump is designed for the rated operating condition. Therefore, the volumetric efficiency becomes worse when the rotating rate becomes lower.
