Exhaust flap devices for an internal combustion engine are known, having a flap housing (10), in which a duct (12) through which exhaust gas flows is formed, an exhaust flap (14), which is arranged rotatably in the exhaust duct (12) and is mounted in the flap housing (10), an actuator (28) having an actuator housing (30) and an electric motor (32), by means of which the exhaust flap (14) can be driven, and a coolant duct (42), which is formed in the flap housing (10) and at least partially surrounds the exhaust flap (14). In order to ensure sufficient cooling of an actuator, by means of which the exhaust flap (14) is driven, without further interfaces, the coolant duct (42) in the flap housing (10) has a direct fluid connection to a coolant duct (44) in the actuator housing (30). |
