Title: Lucien Hehn: Innovator in Fuel Injection Technology
Introduction
Lucien Hehn is a notable inventor based in Villeurbanne, France. He has made significant contributions to the field of fuel injection technology, holding 2 patents that showcase his innovative approach to engineering.
Latest Patents
His latest patents include a process and apparatus for controlling and measuring the movement of a fuel injection device for internal combustion engines. This invention features a high-pressure pump with a pump work chamber, which includes a fuel injection valve with a pressure chamber. The design incorporates a pressure line that connects the pressure chamber with the pump work chamber. Additionally, it has a relief conduit controlled by a relief valve that automatically blocks the relief conduit during the high-pressure phase and opens at the beginning of the cutoff. This mechanism increases the closing pressure exerted on the fuel injection valve after the end of the injection operation. The pressure line also includes a pressure valve that opens in the supply direction and closes upon the beginning of the cutoff. The relief valve is urged in the opening direction by the pressure in the pressure chamber during the high-pressure phase and opens during the flow of fuel from the chamber toward the spring chamber of the injection valve, simultaneously with a decrease in pressure in the pump work chamber.
