Abstract: Exhaust gas recirculation valve actuator device in an internal combustion engine, comprising an actuator body housing where the stem of an exhaust gas recirculation valve, extends along an axial direction. A motor acts to move the recirculation valve along the axial direction X-X, to pass from an open configuration to a closed configuration. A transmission is interposed between the motor and the exhaust gas recirculation valve. The device also includes support and guide mechanism and a sealing mechanism, in correspondence of a connection interface of the actuator body with an associable valve body, which houses an exhaust gas passage duct, wherein the actuator body is mechanically separable/connectable from/to said associable valve body.

Abstract: A throttle body or actuator for an engine, comprising a main body which defines at least one supply duct having a through lumen for a gas mixture, a choke valve placed inside said supply duct so as to modify said through lumen. The choke valve is provided with an occluding body connected to a control shaft, at least partially housed in a seat in the main body. The control shaft, inside the seat and on the side of the occluding body, is provided with a first gasket adapted to prevent the penetration of dirt and gas from the supply duct. Downstream of the first gasket, on the side of the control shaft, at least one vent is provided, adapted to allow the expulsion, outside the seat, of any gas which has leaked through the first gasket.
