Abstract

An exhaust gate, in particular for a heavy-goods vehicle, has a housing, which has an inlet and first and second outlets, on which first and second valve seats are formed, and a valve flap, which can be pivoted between the two valve seats to close the first or second outlet. The housing is formed as a cast part, which connects the inlet and at least the first outlet integrally to each other. The valve flap has a larger cross section than the inlet and the first and second valve seats.
