Title: The Innovations of Henry Roger Leclerc
Introduction
Henry Roger Leclerc is a notable inventor based in Juvisy sur Orge, France. He has made significant contributions to the field of engineering, particularly in the design of devices related to pistons and fuel metering in turbomachines. With a total of 6 patents to his name, Leclerc's work showcases his innovative spirit and technical expertise.
Latest Patents
One of Leclerc's latest inventions is a device for measuring the position of a piston in a cylinder. This device features at least two position sensors, with a first sensor member integrated with a supporting pallet linked to the piston. The second sensor member is integral with the cylinder, allowing for mobile translation along an axis parallel to the cylinder. This design ensures that the position sensor can be arranged in the cylinder without transmitting transversal strains on the piston, allowing for free rotation about the axis of the cylindrical barrel.
Another significant patent is the fuel metering unit with a compensated regulator valve in a turbomachine. This unit connects a high-pressure pump, which draws fuel from a tank, to multiple fuel injectors in the combustion chamber. The unit includes a meter that receives fuel from a regulator valve and delivers it to the injectors via a stop valve. The regulator valve recirculates fuel back to the high-pressure pump based on the pressure difference between the meter and the injectors.
