Abstract
A gasket for an exhaust system comprises a metallic plate having an exhaust sealing segment and a coolant sealing segment which is attached to and extends from the exhaust sealing segment. Both segments have first and second planar surfaces on opposite sides thereof, with the first and second planar surfaces of the exhaust sealing segment being co-planar with the first and second planar surfaces of the coolant sealing segment, respectively. An exhaust opening is formed through the plate and first and second elastomeric seals, which can be silicone rubber and which are both integral parts of a common elastomeric element, are disposed on the first and second surfaces, respectively, of the coolant sealing segment. A raised portion of the exhaust opening through the metal plate extends at an angle from the exhaust sealing segment and away from the first surface to form a transition segment from a first opening to a second. A hole can be formed through the plate and located at a central region of the coolant sealing segment with the common elastomeric element extending through the hole with the first and second elastomeric seals being joined to each other within the hole. A central portion of the coolant sealing segments can either comprise a hole to allow liquid to flow through the thickness of the plate, or alternatively, can comprise a solid portion that inhibits a flow of liquid through the thickness of the plate.
