Title: Innovations of Robert H Ash, Jr.

Introduction

Robert H Ash, Jr. is a notable inventor based in Humble, TX (US), recognized for his contributions to the field of engineering with a total of 5 patents. His work primarily focuses on advancements in pump technology, showcasing innovative designs that enhance efficiency and performance.

Latest Patents

One of his latest inventions is the "Pump having unidirectional tapered land thrust bearing cluster." This invention pertains to a single-piece unidirectional tapered land thrust bearing cluster designed for use in high-pressure positive-displacement swashplate piston pumps. The bearing cluster features a plurality of identical bearing pads that are integral to the cluster. Each bearing pad includes a tapered section, a flat section, and a fluid communicating slot. During the operation of the pump, the swashplate camming surface rotates relative to the bearing cluster, developing a pressurized load-carrying hydrodynamic film of decreasing thickness and increasing strength between the back plate of the rotating swashplate and the bearing cluster.

Another significant patent is the "Positive displacement pump having levitating magnetic piston spring." This invention includes a plurality of pistons that are reciprocally driven in respective cylinders by a swashplate assembly to expel fluid during the pressure stroke. Oppositely disposed magnets are located in the upper pressure face of each piston and in a check valve housing adjacent to each cylinder. This configuration produces a magnetic force circuit that accelerates the movement of each piston toward and maintains continual contact with a cluster bearing associated with the swashplate assembly during the suction stroke. The design utilizes like poles of each magnet facing each other to create a permanent levitating force on each piston.
