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: 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.

Abstract: An assembly provides a proportioned gas flow and includes a device that provides a pressurized flow of said gas, a release unit that releases the proportioned gas flow, and a chamber having an inlet fluidically connected to the device and an outlet fluidically connected to the release unit. The assembly further includes an admission valve inserted between the inlet of the chamber and the device, a metering valve inserted between the outlet of the chamber and the release unit, and a computer programmed to control the admission valve and the metering valve to provide a proportioned gas flow to the release unit. The assembly further comprises a calibrated orifice inserted between the outlet of the chamber and the release unit.
