  • Fuel pump for an internal combustion engine
    Publication number: 20050207912
    Abstract: In a fuel pump for an internal combustion engine, a pumping device is adapted to vary the volume of a first chamber containing the fuel and is formed by a second chamber adapted to contain oil, a deformable diaphragm for the leak-tight separation of the chambers from one another, and by a piston mounted to slide within the second chamber and comprising an active end surface bounding this second chamber; the diaphragm being adapted to be deformed to vary the volume of the first chamber under the action of the thrust exerted by the oil contained in the second chamber following an alternating movement of the piston within this second chamber.

  • Fuel injector with piezoelectric actuator
    Patent number: 6834812
    Abstract: Fuel injector provided with a piezoelectric actuator, a valve activated by the piezoelectric actuator and regulating a fuel supply that flows in a working direction, and a mechanical transmission placed between the piezoelectric actuator and the valve; an expansion of the piezoelectric actuator displaces the valve in the working direction from a closed position to an open position in an opposite direction to that of the fuel outlet.

  • Fuel injector with a piezoelectric actuator housed in an insulated chamber
    Patent number: 6772963
    Abstract: A fuel injector having a piezoelectric actuator, which activates a shutter to move the shutter in a work direction between a closed position and an open position; the piezoelectric actuator is housed inside a casing having an inner chamber insulated from the fuel, and an outer surface wet by the fuel.
