SCARIC GAS RECIRCULATION VALVE (EGR) ATTORNEY ON AN ENDOTERMIC ENDOTERM ENGINE ENDOTERM ENGINE AND RELATED SCARCH GAS RECIRCULATION VALVE GROUP

摘要

Exhaust gas recirculation (EGR) valve actuator device (4) in an internal combustion engine, comprising an actuator body (8) housing - the stem (12) of an exhaust gas recirculation valve (16), extending along an axial direction (X-X), - motor means (32) of said exhaust gas recirculation valve (16) configured so as to move the recirculation valve (16) along said axial direction (X-X), to pass from an open configuration to a closed configuration, - transmission means (36), interposed between the motor means (32) and the exhaust gas recirculation valve (16), - support and guide means (40) of the exhaust gas recirculation valve (16) - heat reducing and sealing means (76), in correspondence of a connection interface (80) of the actuator body (8) with an associable valve body (84), which houses an exhaust gas passage duct (88), wherein the actuator body (8) is mechanically separable/connectable from/to said associable valve body (84).
