  • Patent number: 11408315
    Abstract: The device for injecting a fluid into an exhaust pipe comprises a fluid reservoir, an enclosure delimiting a fluid heating chamber, and a first injection system configured to inject the fluid from the reservoir into the heating chamber. At least one heating element extends at least partially into the heating chamber and is intended to be in contact with the fluid, with the at least one heating element being configured to heat the fluid. A second injection system is configured to inject the heated fluid from the heating chamber into the exhaust pipe.
    Type: Grant

  • Patent number: 6779643
    Abstract: A friction clutch comprising a pressure plate (12) consisting of tow half-plates (12A, 12B) integral in rotation with the input shaft but axially mobile, relative to each other, under the action of the device compensating play due to wear. The wear compensating device comprises a pair of complementary ramps (17, 18) circumferentially arranged, axially associated respectively with each of the half-plates (12A, 12B), one support ramp (17) being integral in rotation to one (12B) of the half-plates, the other adjustment ramp (18) being adapted to move circumferentially relative to the support ramp (17) in the compensating direction increasing the global thickness of the first plate (12) and prevented form moving in the other direction by one-way means (24). The circumferential movement is controlled by a tripping element (22) sensitive to wear condition, the adjusting ramp (18) being arranged at the periphery of an inertial piece (12A).

  • Patent number: 6657337
    Abstract: An electric motor for motor vehicle actuators include a rotor provided with a coil having first and second radial ends and rotatingly mounted in a hollow frame of two parts directly mounted on each other and having end walls, the two parts are made of good heat conducting material. The frame bears an inductor. The frame is sealed, and the two parts are two components transversely assembled one on the other, and the end wall of each part is continuously adjacent to one of the first and second ends of the coil.

  • Publication number: 20030141163
    Abstract: The invention concerns a friction clutch for a heat engine motor vehicle, comprising a reaction plate (13), a friction disc (14), a pressure plate (12), a cover (11), the pressure plate (12) consisting of two half-plates (12A, 12B) integral in rotation with the input shaft but axially mobile, relative to each other, under the action of a device compensating play due to wear which comprises a pair of complementary ramps (17, 18) circumferentially arranged, axially associated respectively with each of the half-plates (12A, 12B), one of the ramps (17) called support ramp being integral in rotation to one (12B) of the half-plates, the other ramp (18) called adjustment ramp, being adapted to move circumferentially relative to the support ramp (17) in the direction increasing the global thickness of the first plate (12), called compensating direction, and prevented from moving in the other direction by one way means (24), said circumferential movement being controlled by a tripping element (22) sensitive to wear co
