DESCRIPTION

The pump illustrated in Fig.

1 consists principally of

a ported body, a drive shaft supported by two ball

bearings, a pumping cartridge and a pressure plate.

The

components of the cartridge are an elliptical ring, a

slotted rotor splined to the drive shaft and twelve vanes

fitted to the rotor slots.

As the rotor is driven by the drive

shaft, the vanes generate fluid flow by carrying fluid

around the elliptical ring contour. Fluid enters the

cartridge through the inlet port in the body and is

discharged through the pressure plate to the outlet port

in the cover,
