As mentioned in Section II, fluid flow is developed in the pumping cartridge. The action of the cartridge is illustrated
in Figure 2. The rotor is driven within the ring by the drive shaft, which is coupled to a power source. As the rotor
turns, centrifugal force on the vanes, aided by under-vane pressure fed from the outlet port, causes the vanes to follow
the elliptical inner surface of the ring.

Radial movement of the vanes and turning of the rotor causes the chamber volume between the vanes to increase
as the vanes pass the inlet sections of the ring. This results in a low pressure condition which allows atmospheric
pressure to force fluid into the chambers.
An additional inlet fluid path exists through a drilled hole in the cam ring. This hole connects the inlet port directly
to the inlet areas of the cam ring and provides an additional flow path for fluid to get into the cartridge. See Figure
1 and 15.
