24	Ultra-low friction air pump for creating oscillatory or pulsed jets	US13178699	2011-07-08	US08714945B2	2014-05-06	Terrence S. Birchette
An air pump positioned within a hollow space in an aerodynamic structure for controlling the flow over an aerodynamic surface thereof, includes a movable member linearly displaced by a very low friction piston mechanism and a compression chamber open to the exterior of the aerodynamic surface through an orifice. Reciprocal displacement of the very low friction movable member changes the volume of the compression chamber to alternately expel fluid (e.g., air) from and pull fluid into the compression chamber through the orifice. The movable member includes a piston oscillating within a piston housing each having an ultra-low friction coating for improved thermal performance and reduced maintenance. Fluid intake to the compression chamber may be increased through the use of a one-way valve located either in the aerodynamic surface, or in the piston. Multiple flapper valves may surround the orifice in the aerodynamic surface for increased fluid control.

A swash pump for compressible fluids uses sealing contacts made between the nutatable swash plate and the fixed cone plates to center and locate the inner swash sphere which slides against two resiliently mounted ring seals only, minimizing pump friction. A slanted end of a common drive shaft supporting and turned by the rotor of an integrated, variable speed motor causes nutation of the sphere. All bearings, especially axially slidable roller bearings inside the sphere, may settle in position with respect to the common shaft for least frictional loss. This pump is also adapted for pumping explosive gases.

A medium, optionally compressed or pressurized, is discharged via an outlet valve (8). In the course of movement from one reversal position into the other reversal position, an inlet valve (9) being opened; after which, in the course of a pressure buildup, the medium is discharged on a pressure side of the pump piston (2, 3) and taken in on a suction side of the pump piston (2, 3).
36	Birotational pump	US248731	1988-09-26	US4861236A	1989-08-29	Ryon Kustes; Alan M. Kustes
This invention comprises a birotational pump for the movement of air fluid through a conventional pumping mechanism. It is comprised of cylindrical piston housing, a pump shaft running through the piston housing, a piston linkage assembly secured to the pump shaft, a pair of valve plates which cover the ends of the piston housing and a cylindrical pump housing surrounding the piston housing to allow for the free movement of the piston and piston linkage. This invention will permit the free flow of fluid or air through the piston housing by creating a suction chamber in the piston housing. The fluid enters the valve plates which contain openings which line up with openings in the piston housing. As the shaft rotates the openings on the first end of the piston housing cease to line up with openings in the piston housing and openings in the second end line up to expel the fluid contained within the chamber of the piston housing cirutier of rotation of shaft can be changed. Because of the unique arrangement of the piston housing and the rotational ring washers and their pins, the pump will operate to pump fluid regardless of the direction of rotation of the pump shaft.
