Vane Pump

A fluid pump consisting of a slotted rotor that turns within a pump liner or cam ring. The rotor is milled with radial slots in which vanes (blades/plates) float, being thrust out by centrifugal force into the liner to form pump chambers when the rotor turns.

Positive Displacement

Accumulators

Devices in hydraulic systems that store fluid under pressure, used to absorb shock or maintain pressure.
