Abstract: A snap-action valve assembly for an exhaust system and a method for manufacturing the same is provided. The valve assembly includes a first conduit and a second conduit that is partially received in the first conduit. A valve flap is disposed within the first conduit for controlling exhaust flow. A shaft supports the valve flap in the first conduit for rotation between open and closed positions. The first conduit has first and second slots, each extending from an open slot end to a closed slot end. First and second bushings supporting the shaft are disposed within the slots between the second conduit and the closed slot ends. A pad made of wire mesh is attached to the valve flap. The pad includes an end portion that contacts the first conduit in the closed position to dampen vibration and reduce valve flap flutter.

Abstract: A fluid delivery system for an exhaust aftertreatment system includes a pump disposed within an outer housing. A filter assembly is in fluid communication with the pump and also disposed within the outer housing. A tubular filter medium is disposed within a pump housing. An elongated first compensation element is disposed within an elongated aperture of the filter medium. A support ring is associated with the pump housing and includes a plurality of flexible arms. Second and third compensation elements are also provided to contract in response to expansion of fluid within the pump housing due to freezing and expand in response to thawing of the fluid.

Abstract: A fluid delivery system for an exhaust aftertreatment system may include an outer housing, a pump, a filter assembly, an electric heating blanket, and a heater retention plate. The heater retention plate is shaped to correspond to the shapes of the pump and filter assembly. A lid of the outer housing contacts the heater retention plate and clamps the heating blanket between the heater retention plate and the pump and filter assembly so that the heating blanket takes the shapes of portions of the pump and filter assembly. The outer housing includes mounting flanges and reinforcement members extending from corresponding mounting flanges to corresponding sidewalls of the outer housing and forming a hollow space therebetween. The filter assembly includes compensation elements that contract in response to expansion of fluid within a pump housing due to freezing and expand in response to thawing of the fluid.

The valve assembly includes a first conduit and a second conduit that is partially received in the first conduit. A valve flap is disposed within the first conduit for controlling exhaust flow. A shaft supports the valve flap in the first conduit for rotation between open and closed positions. The first conduit has first and second slots, each extending from an open slot end to a closed slot end. First and second bushings subassemblies supporting the shaft are disposed within the slots between the second conduit and the closed slot ends. Each of the first and second bushing subassemblies includes an alignment system in the form of protrusions that limit insertion of the first and second bushing subassemblies into the first and second slot to a single orientation.

Abstract: A snap-action valve assembly for an exhaust system is provided that includes a first conduit and a second conduit that are joined to together to define an exhaust passageway. A valve flap is disposed within the exhaust passageway for controlling exhaust flow. A shaft supports the valve flap in the exhaust passageway for rotation between open and closed positions. First and second bushings support the shaft. A pad made of wire mesh is attached to the valve flap. The pad includes an end portion that contacts the first or second conduit in the closed position and side wings that contact the first or second conduit in the open position. A resilient tongue may support the pad on an angle relative to the valve flap and a mass damper may be attached to one end of the shaft. These features dampen vibration and reduce valve flap flutter.
