Abstract: An electric actuator comprises a motor and a plate, wherein the motor has an electric contact in electrical contact with the plate. An intermediate shaft is in contact with the plate. A controller is fixed to an upper part of the actuator. The controller has an electrical output electrically communicating with the electric contact of the motor through the intermediate shaft and the plate.

Abstract: A valve comprises a coupling device having a driven member bound to the drive shaft of a flap, a driving member bound to an output shaft of an actuator, and an elastic member. The driving member comprises attachments that hooks up the elastic member to the driving member in a temporary position in which the elastic member is elastically loaded. The driven member comprises at least one release member that at least partly releases the elastic member of the attachments when the coupling device is brought to an intermediate state or the elastic member, when the coupling device is in the intermediate state, may be at least partly released from the attachments. The elastic member once released, adopts a definitive use position under the effect of relaxation of the elastic load, the coupling device then adopting the operational state.

Abstract: A valve includes a valve body having an exhaust gas inlet and an exhaust gas outlet, the valve body defining an exhaust gas circulation passage between the exhaust gas inlet and the exhaust gas outlet. A flap is arranged in the valve body and a shaft drives the flap in rotation with respect to the valve body. At least one guide bearing guides the drive shaft of the flap for rotation relative to the valve body. The guide bearing is engaged through an orifice of the valve body, with an inner end of the guide bearing being located inside the valve body. A first tube is engaged in one of the exhaust gas inlet and exhaust gas outlet and abuts against the inner end of the guide bearing.

Abstract: A valve comprises a valve body delimiting a passage for exhaust gases, a flap arranged in the valve body, and a drive shaft configured to drive the flap, and which is integrally secured to the flap. At least one guide bearing is configured to guide the drive shaft of the flap in rotation in relation to the valve body, and is connected to the valve body. The valve also includes an actuator and a transmission comprising an adapter rigidly attached directly to the drive shaft of the flap. The transmission is arranged in order to transmit a motor torque between the actuator and the adapter. The adapter has a contact surface that is in sealed contact with a complementary surface provided on the guide bearing.

Abstract: An exhaust valve includes a body defining a passage and a flap that pivots about an axis relative to the body to selectively close/open the passage. An actuator moves the flap and a device couples the flap to the actuator. This coupling device comprises: a compression spring having a proximal end that rotates about the axis with a first element between the flap and an actuator output shaft and a distal end; a seat engaged with the distal end, while the seat is fixed in rotation about the axis with the first element, and a torsionally-rigid transmission member fixed in rotation about the axis with the first element and that immobilizes the distal end relative to the proximal end in a plane that is orthogonal to the axis. The transmission member has a slot that is elongated parallel to the axis and is traversed by the distal end.
