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 Xa 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.

Actuator for the actuation of at least one movable member, in particular for changing gear ratios in a motor vehicle transmission

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 X, 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 Xbetween 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.

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 X, 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 Xand 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.

The invention pertains to a valve, particularly an exhaust gas recirculation valve, said valve comprising a conduit () for circulating a cooling fluid having a wall () intended to come in contact with a circulation flange of said cooling fluid, said wall () having a plurality of grooves () and ribs () configured to limit contact between said flange and said wall () at said ribs (), said ribs () being formed by machining and said grooves () being produced from molding the valve.

Valve, particularly an exhaust gas recirculation valve

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.
