Title: Innovations of Neil F. Hoelhe

Introduction

Neil F. Hoelhe is an accomplished inventor based in Solon, Iowa, with a notable portfolio of three patents. His work primarily focuses on advanced sealing technologies that address challenges in shaft alignment and pressure management.

Latest Patents

One of his latest innovations is the pressure balanced shaft seal assembly. This assembly allows a seal to dynamically respond to angular or radial misalignment of a shaft. It includes a fixed stator, a floating stator, and a labyrinth seal. The design enables the floating stator and labyrinth seal to move within an annular groove formed in the fixed stator, accommodating radial movement. A spherical interface between the labyrinth seal and floating stator permits pivoting during angular misalignment. Additionally, a pressure balancing annular channel in the floating stator helps balance the axial pressure exerted by the process fluid. Another significant patent is the shaft seal assembly, which maintains a seal during shaft misalignment. This assembly features multiple sealing means that work together to respond to forces produced by angular misalignment while maintaining a defined clearance between the shaft and sealing means.
