Title: The Innovations of Jean Doreau
Introduction
Jean Doreau is a notable inventor based in Vigny, France, recognized for his contributions to engineering and technology. With a total of two patents to his name, Doreau has made significant advancements in fuel injection systems and fire control technology.
Latest Patents
Doreau's latest patents include a direct injection fuel pump designed for engines with controlled ignition. This innovative injection pump consists of several modules housed together, where each module features a chamber that supplies an injection circuit. The chambers are separated by a deformable diaphragm from a compartment defined by a bore of the housing and a reciprocating piston. Each chamber connects to a fuel supply and the injection circuit through a non-return valve, allowing for independent pressure adjustments in each compartment. All pistons are driven by the same cam, enhancing the efficiency of the system.
Another significant patent is a fire control system equipped with aiming error compensation. This system is designed for weapons with an operator-aimed barrel. It includes a sighting piece that carries a reticle adjustable in position relative to the bore axis of the barrel. A camera, fixed to the barrel, has a field that is coaxial with the bore axis. The system measures the apparent movement of the target in the camera's field, as well as the angular movements of the barrel by the operator. The reticle's position is computed based on variations in the aiming direction and is adjusted accordingly, potentially utilizing an LCD display for the reticle.
