Title: The Innovative Contributions of Eric S. Keyster
Introduction
Eric S. Keyster is a notable inventor based in Peoria, IL (US). He has made significant contributions to the field of engineering, particularly in the design and functionality of axial piston pumps. With a total of 7 patents to his name, Keyster's work has had a considerable impact on fluid dynamics and pump technology.
Latest Patents
Among his latest patents, Keyster has developed an "Axial piston pump with outer diameter inlet filling." This invention features a variable delivery fixed displacement pump that includes a rotating drive plate with a fixed angle. The design incorporates a fill passage that allows fluid to be supplied to a fluid journal bearing, along with a series of bearing supply passages that connect the drive surface of the drive plate with a base surface. This innovative method of pumping fluid involves reciprocating a plurality of pistons by rotating the drive plate and fluidly connecting the pumping chamber to an annular groove in the drive plate fill passage.
Another significant patent is the "Axial piston pump with center inlet fill." This design utilizes a hydrostatic thrust bearing and a hydrodynamic journal bearing to support a rotating wobble type drive plate. The rotation of the drive plate causes multiple parallel pistons to reciprocate, with the pumping chambers fluidly connected to the inlet and outlet via strategically designed passages. This design exploits centrifugal forces to enhance the supply of low-pressure fluid to the pistons, particularly at higher speeds.
