Abstract
A flap valve for a motor vehicle exhaust system includes a valve housing in which a valve flap is pivotally mounted about a shaft. A bearing housing is disposed in a gas-tight manner outside the valve housing. The shaft is extended through a first orifice in the valve housing and emerges from the bearing housing through a second orifice. Inside the bearing housing, the shaft is surrounded by a bearing ring having a supporting surface pointing towards the valve flap. A spring element, which is mounted in the bearing housing, surrounds the shaft and is supported at the supporting surface and directly or indirectly at the shaft.
