ELECTRIC EXHAUST GAS VALVE DEVICE

An electric exhaust gas valve device (1) controls a flow cross section (5) of an exhaust pipe (6) of an exhaust system (8) of an internal combustion engine. The valve device includes an electric drive (2) driving a driven shaft (9) rotatingly about an axis of rotation (10). An exhaust gas valve (3)...

Beschreibung
Zusammenfassung:	An electric exhaust gas valve device (1) controls a flow cross section (5) of an exhaust pipe (6) of an exhaust system (8) of an internal combustion engine. The valve device includes an electric drive (2) driving a driven shaft (9) rotatingly about an axis of rotation (10). An exhaust gas valve (3) has a drive shaft (12) aligned coaxially to and rotatable about the axis of rotation for controlling the cross section. A coupling device (4) transmits torques between the driven shaft and the drive shaft and includes a connection element connected to the drive shaft, a transmission element (16) connected to the driven shaft and the connection element with a prestressing spring (18) supported axially on the connection element and/or on the drive shaft as well as on the transmission element and axially driving the transmission element against the driven shaft to reduce thermal load.
