Title: ELECTRIC ACTUATOR FOR AN INTERNAL COMBUSTION ENGINE
Abstract:
The invention relates to an electric actuator (10) for an internal combustion engine, comprising an actuating element (12) and an actuating mechanism (14) for actuating the actuating element (12). The actuating mechanism (14) has a fixed internal gear (16) with internal teeth, a rotor disc (18) that rotates coaxially with the internal gear (16), said disc being driven by an electric rotary drive (20), a planetary gear (22) with external teeth that is mounted excentrically on the rotor disc (18) in a rotating manner and a follower (24) that is excentrically associated with the planetary gear (22) in a fixed manner and actuates the actuating element (12).
