Abstract

This invention is for a positive displacement type of pump similar to peristaltic pump functions. This pumping apparatus could produce very low flow and very high pressure. The pumping action of this rotary pump comes from squeezing liquid around a groove using rotating bearings which press the liquid to the end of the groove and discharges the fluid at the end of the groove (with potentially very high pressure).

This invention is for a positive displacement type of pump similar to peristaltic pump functions. This pumping apparatus could produce very low flow and very high pressure. The pumping action of this rotary pump comes from squeezing liquid around a groove using rotating bearings which press the liquid to the end of the groove and discharges the fluid at the end of the groove (with potentially very high pressure). See attached conceptual schematics. The pump uses a series of rotating bearings (possibly tapered roller bearings) pressed tightly against a membrane. Well fluid only has access to one side of the membrane, the pumping side of the membrane, the other side of the membrane (the bearing side of the membrane) would only be exposed to the clean lubricant of the motor. The bearings would require a high face load. A reaction bearing would allow the pumping bearing to be pre-loaded...
