Title: Innovations of Louis R. Erwin

Introduction

Louis R. Erwin is a notable inventor based in Livonia, MI (US). He holds a total of 5 patents that showcase his contributions to the field of engineering and technology. His work primarily focuses on fluid dynamics and pressure regulation, which are critical in various applications.

Latest Patents

One of his latest patents is a flow-controlled pressure regulating device. This invention features a pressure regulating nozzle that can be integrated within a fluid supplying device, such as a fuel injector. The nozzle comprises a reciprocating piston that moves a plunger located within an outlet bore. The piston contains multiple control orifices that create a controlled pressure drop, ensuring that the pressure within the nozzle remains relatively constant. Additionally, the nozzle includes a series orifice that isolates the piston from upstream pressure surges, allowing for the development of rate feedback forces to dampen the piston’s motion. Another embodiment of this invention illustrates a by-pass pressure regulator that incorporates these innovative features.

Another significant patent is a control valve designed for use with variable displacement piston pumps. This valve responds to pump discharge manifold pressure to control the pressure in the pump chamber. The controlled pressure generates a force that regulates the stroke of the pump pistons, maintaining a predetermined, substantially constant pressure while allowing for variable fluid flow through the pump.
