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.

Exhaust gate

The invention relates to an exhaust gas control valve with a first valve part ( ) and a second valve part ( ), which rest on one another with one side ( ), the valve parts ( ) in each case having passages ( ) and being rotatable relative to one another between an open position permitting the passage of exhaust gases and a closed position, blocking this passage. Webs ( to ), which protrude on one axial side of the first valve part ( ), surround the openings ( ) and, with their free narrow surfaces, form supporting surfaces for the second valve part ( ), which is constructed flat on its side ( ) facing the first valve part ( ) and essentially rests with this surface on the narrow surfaces of the webs ( to ) and slides during the relative rotational adjustment, extend along the boundary edges ( to ), surrounding the passages ( ) of the first valve part ( ).
