Abstract:
An actuator for the actuation of at least one movable member of a motor vehicle transmission. The actuator includes a housing, at least one electric motor having a stator and a rotor mounted on a rotor shaft extending along an axis X1, a motor pinion fixed to the opposite end of the shaft from the rotor, a circuit board for supplying power to the stator and controlling the electric motor, and a reduction mechanism driven by the motor pinion. The housing defines a first volume in which the electric motor and the circuit board are received. The circuit board is located axially along the axis X1 between the electric motor and the motor pinion. The actuator further includes a cover defining a second volume in which the reduction mechanism is received, the housing and the cover each have guides for guiding the reduction mechanism.
Abstract:
The invention relates to a coolant-supplying flange for a component to be cooled, especially an exhaust gas recirculation valve, said flange comprising a centring drum (3) in a duct (4) for the circulation of said coolant in said component, said drum (3) extending in an axial direction, said drum (3) being crossed by a channel (6) for the circulation of said coolant, extending in said axial direction, said drum (3) having at least one passage (13) allowing a transverse circulation of the fluid between said circulation duct (4) of the component and said circulation channel (6) of said flange.
Abstract:
The invention pertains to a valve, particularly an exhaust gas recirculation valve, said valve comprising a conduit (4) for circulating a cooling fluid having a wall (10) intended to come in contact with a circulation flange of said cooling fluid, said wall (10) having a plurality of grooves (16) and ribs (14) configured to limit contact between said flange and said wall (1) at said ribs (14), said ribs (14) being formed by machining and said grooves (16) being produced from molding the valve.
Abstract:
An actuator for the actuation of at least one movable member of a motor vehicle transmission. The actuator includes a housing and a cover defining an internal volume in which are received at least one electric motor having a stator and a rotor mounted on a rotor shaft extending along an axis X1, a motor pinion fixed to the opposite end of the shaft from the rotor, a circuit board for supplying power to the stator and controlling the electric motor, and a reduction mechanism driven by the motor pinion. The housing or the cover includes an electrical connector which incorporates a semipermeable membrane allowing an exchange of gas between the inside of the actuator and the external surroundings.
Abstract:
The invention relates to a valve (1), such as a valve for a motor vehicle and, in particular, an exhaust gas recirculation valve, comprising a valve body (2) including at least one housing (34; 15) for receiving a member (20) of the valve, preferably two housings (34, 15) for receiving valve members, said member(s) preferably having a substantially tubular shape, the base of the housing(s) (34; 15) having at least one rib (40, 42), preferably at least two ribs (40, 42), in contact with the valve member (20). The invention also relates to a method for the production of such a valve.

The actuator includes a housing and a cover defining an internal volume in which are received at least one electric motor having a stator and a rotor mounted on a rotor shaft extending along an axis X1, a motor pinion fixed to the opposite end of the shaft to the rotor, a reduction mechanism driven by the motor pinion, a pin mounted so as to be able to rotate at the end of a shaft extending along an axis X3 and able to be engaged in the movable member of the transmission. The shaft of the pin is rotationally guided by a rolling bearing and a slide bearing.
Abstract:
A fluid flow valve that includes a movable closure member and a body that includes a projecting part that receives the closure member. The body is designed to be attached to a support in such a way that the projecting part is introduced into a housing in the support. In addition, the body is designed to allow the valve to be secured to the support in a direction transverse to a longitudinal direction of extension of the projecting part. The invention is suitable for the recirculation of exhaust gases of motor vehicle engines.
