Abstract (en)
[origin: WO2018197262A1] Control devices for internal combustion engines are known, comprising an intake channel (12) having an inlet (14) and an outlet (20), an exhaust gas return channel (16) which feeds into the intake channel (12), a control element (46), an opening (18) of the exhaust gas return channel (16) which functions as a fixed valve seat (58) for the control element (46) in the state closing the exhaust gas return channel (16), and a shaft (42) functioning as the axis of rotation (44) of the control element (46), on which the control element (46) is eccentrically secured, wherein the control element (46) can be moved, by rotating the shaft (42), between a first end position in which the control element (46) at least throttles the intake channel (12), and a second end position in which the control element (46) is in contact with the valve seat (58) at the opening (18) of the exhaust gas return channel (16). According to the invention, in order to reduce the wear in the region of the valve seat, the axis of rotation (44) of the shaft (42) is arranged in a plane (60) passing through the valve seat (58) at the opening (18) of the exhaust gas return channel (16).
