Title: Paul L Feltman, Jr: Innovator in High Pressure Seal Systems
Introduction
Paul L Feltman, Jr. is an accomplished inventor based in Chicago, IL (US). He is known for his innovative contributions to sealing technologies, particularly in high-pressure applications. His work has significant implications for industries that require reliable gas sealing solutions.
Latest Patents
Feltman holds a patent for a "Spiral groove seal system for sealing a high pressure gas." This system is designed to effectively seal a housing and rotatable shaft against the leakage of gases under high pressure, with hydrogen being a notable example. The innovative design employs multiple seals in tandem, allowing for a stepped reduction of high-pressure gas to a lower pressure across individual seal modules. The system features axially spaced spiral-grooved end face seal modules that are mounted between the shaft and housing, creating a chamber defined by the axial spaces between the seals. Each seal module consists of a primary seal ring affixed to the housing and a mating ring that rotates with the shaft, both having opposed, radially extending faces. The mating rings are equipped with a series of radial spiral grooves that extend inward from the outer diameter.
