Definitions:

Cam Ring

An eccentric liner, usually stationary, within which mobile pump members rotate.

Non-Positive

Describes a connection or interaction where movement or slip is permitted between components, as opposed to a fixed, rigid connection.

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

A characteristic of a pump or motor that has its inlet positively sealed from its outlet so that no fluid can recirculate within the component; that is, what goes into the pump per cycle is what comes out per cycle.
