Title: Innovations of Robert W Guertin
Introduction
Robert W Guertin is a notable inventor based in Cincinnati, OH (US), recognized for his contributions to the field of vapor recovery technology. He holds a total of 9 patents, showcasing his innovative spirit and dedication to minimizing environmental pollution.
Latest Patents
One of his latest patents is for vapor recovery nozzles and sub-assemblies designed to minimize atmospheric pollution caused by fuel vapors. This innovative nozzle features a bellows that compresses against the fill pipe of a vehicle's fuel tank during fuel discharge. The bellows surrounds a nozzle spout, creating a vapor return flow path that extends through the nozzle body. The nozzle's body is composed of a body member and a vapor path cap, which together define the vapor return flow passage. Fuel flow is regulated by a control valve that can only be opened when a trip mechanism stem is latched in an operative position. A mechanical interlock ensures that the trip mechanism stem cannot be latched unless the bellows is compressed against the fill pipe. If the fuel level covers the spout's end, vacuum actuated means will unlatch the trip mechanism stem. Additionally, if pressure in the vapor return flow path indicates a blockage, the trip stem will also be unlatched. A vapor valve within the bellows prevents fuel vapors from escaping when the nozzle is at rest. The design includes angular relationships of the bellows and spout to ensure a proper seal with the fill pipe, and a groove adjacent to the vapor seal maintains its integrity even if the spout is damaged during insertion.
