Abstract

A valve device includes a housing, a flow duct and a valve body. The valve body is arranged in the flow duct and has a sealing section that bears against a housing-side sealing seat when the valve device is closed. The sealing section and the sealing seat together form a sealing region. There is a collapse zone immediately upstream of the sealing region in the flow duct when the valve device is closed. The collapse zone is delimited by a boundary wall that is at least substantially perpendicular with respect to a movement axis of the valve body and by a deflector wall that is arranged at an angle with respect to the boundary wall. The boundary wall is longer than the deflector wall.
