  • Hydraulic-Training Axial Piston Units Basic Principles

    2010-7-9 · Pump Function: Through the flexible piston/piston rod arrangement, Principles of Function When used as a pump, the flow is proportional to the input speed and the swivel angle. If the unit is used as a motor, the output speed is proportional to the flow through the unit. The input (pump) or output (motor) torque increases with the pressure …
