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.

An electromechanical actuator to operate a component in an internal combustion engine comprising an actuator body housing, on the inside, an actuator device, which controls the movement of the component so as to move it between a maximum opening position and a maximum closing position, and vice versa. The actuator device includes an electric motor and a gear drive that transmits the motion from the electric motor to the component. The electromechanical actuator is made of a first metal material and comprises a conditioning circuit comprising a pipe for the passage of a conditioning fluid, which is made of a second thermally conductive material. A method of manufacturing the electromagnetic actuator is also disclosed.
