  • Electromagnetic contractor for controlling an electric starter
    Patent number: 7375606
    Abstract: The metal housing of the case of a contactor includes an annular rib extending continuously opposite the cylindrical periphery of the main stationary core, the rib having an internal diameter respectively greater than that of the ferrule and smaller than that of the housing, so as to ensure the locking of the different parts of the case and the crimping of the housing on the stationary magnet following local deformations exerted on the reduced diameter of the swaged part defining the rib.
    Type: Grant
    Filed: March 26, 2004
    Date of Patent: May 20, 2008
    Assignee: Valeo Equipements Electriques Moteur
    Inventors: Frédéric Talon, Pierre Magnier, Christophe Gruet

  • Brush-holder mount for electric machines, such as motor vehicle starter
    Patent number: 6404093
    Abstract: Brush-holder fitting for an electric machine including two components (3, 4) affixed to one another, one (3) which features several guide cages (3c) which each accommodate one brush (1) and a spring (7), the other (4) which constitutes a component forming a seating which includes means allowing it to be assembled onto a metal bearing (5), the component (4) forming a seating including a hub (4h) accommodating an annular element (9) intended to provide rotational guidance for the shaft of the machine, characterized in that the hub (4h) is closed at its extremity intended to be opposite the shaft of the machine, the seating-forming component (4) being able, by itself, to ensure leaktightness with respect to the bearing.

  • Method of manufacturing of a metallurgical mould
    Patent number: 4250943
    Abstract: A method of manufacturing a mold adapted to be used for casting bodies of fiber-reinforced composites. A model of the body to be cast is prepared and coated with a one-piece dense shell of refractory metallic oxide deposited by plasma or flame spraying and the model is then separated from the shell by conventional physical or chemical treatment.
