Title: Paul J Castiglione: Innovator in Hydraulic Systems

Introduction

Paul J Castiglione is a notable inventor based in Milford, MI (US). He has made significant contributions to the field of hydraulic systems, holding a total of 2 patents. His work focuses on innovative solutions for controlling hydraulic pumps, which are essential in various automotive applications.

Latest Patents

One of his latest patents is a "System for controlling multiple hydraulic pumps in an automatic transmission." This system features a viscosity insensitive fixed orifice and a relatively high resistance laminar orifice connected in series. At lower temperatures, the flow through the laminar orifice is negligible, resulting in a minimal steady-state differential pressure across the fixed orifice. As temperatures rise, the flow through the laminar orifice increases, establishing a pressure divider that reduces feedback differential pressure in proportion to the hydraulic resistance of the orifices. This innovation allows for better control of flow to friction elements from both primary and auxiliary pumps.

Another significant patent is the "Assembly of rotary hydraulic pumps." This invention includes a first pump with intermeshing rotors, where the outer rotor is formed with external gear teeth. A second pump also features intermeshing rotors, with its outer rotor continually engaged with the first pump's outer rotor. The design includes pumping chambers that facilitate the movement of hydraulic fluid from a suction inlet to a pressurized outlet, enhancing the efficiency of hydraulic systems.
