A variable displacement pump is a device that converts mechanical energy to hydraulic (fluid) energy.
The displacement, or amount of fluid pumped per revolution of the pump's input shaft can be varied
while the pump is running.
Many variable displacement pumps are "reversible", meaning that they can act as a hydraulic
motor and convert fluid energy into mechanical energy.
An efficient variation is the bent axis pump. Bending the axis reduces side loads on the pistons.
Piston pumps can be made variable-displacement by inserting springs inline with the pistons.
The displacement is not positively controlled, but decreases as back-pressure increases.
Another variation is the variable displacement vane pump.
