Abstract
The invention relates to a switch valve for the exhaust gases of an internal combustion engine. The switch valve includes a housing part in which an inlet and a first outlet and a second outlet are formed. A directional control member in the form of a swinging flap is located within the housing part and either the first outlet or the second outlet may selectively be closed, as a result of which the respective other outlet is in connection with the inlet. In order to minimize the production effort while achieving a simple structural design and high efficiency, it is proposed that an encircling rim, for establishing sealing contact with the flap, is formed in the interior of the housing part in the transitional region between the inlet and each of the outlets, each rim defining a stop plane for the flap.
