  • Patent number: 9845893
    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.
    Type: Grant

  • Patent number: 6726174
    Abstract: The invention relates to an exhaust gas control valve with a first valve part (14) and a second valve part (44), which rest on one another with one side (17, 46), the valve parts (14, 44) in each case having passages (14, 45) 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 (21 to 23), which protrude on one axial side of the first valve part (14), surround the openings (15) and, with their free narrow surfaces, form supporting surfaces for the second valve part (44), which is constructed flat on its side (46) facing the first valve part (14) and essentially rests with this surface on the narrow surfaces of the webs (21 to 23) and slides during the relative rotational adjustment, extend along the boundary edges (18 to 20), surrounding the passages (15, 45) of the first valve part (14).
