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.
