Introduction

David J Parrish is a notable inventor based in Wake Forest, NC (US). He has made significant contributions to the field of engineering, particularly in the design of fuel dispensing systems. With a total of three patents to his name, Parrish continues to push the boundaries of innovation.

Latest Patents

One of his latest patents is a multi-compartment spout for a fuel dispensing nozzle. This innovative design features a cylindrical, longitudinally extending outer wall, along with at least one interior, longitudinally extending dividing wall. The dividing wall creates a fuel passageway that connects with the nozzle's body for dispensing fuel into a vehicle's fuel tank. Additionally, it includes a vapor recovery passageway that prevents fuel vapor from escaping into the atmosphere by returning it to an underground tank. A preferred embodiment of the spout also incorporates another interior dividing wall that defines a shut-off passageway. This passageway communicates with a venturi-vacuum chamber in the nozzle, automatically shutting off the fuel flow when the vehicle's fuel tank is full. The spout is extruded from a lightweight metal, while the nozzle body is molded from a composite resin.
