    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.

    Abstract: An exhaust assembly for a vehicle includes a hanger and an exhaust pipe assembly. The hanger is configured to be fixed to a body of the vehicle. The exhaust pipe assembly includes a first portion and a second portion. The first portion is at least partially disposed inside the second portion so that the second portion overlaps the first portion at a joining region. The joining region has a first outer diameter and is flanked by outer regions having a second outer diameter that is greater than the first outer diameter. An interference fit may be provided between the first portion and the second portion. The hanger is joined to an outer surface of the exhaust pipe assembly at the joining region.

    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 strut-type damper is disclosed. The damper has a shock absorber having a housing with a telescoping piston rod, a coil spring, an upper spring seat operably coupled to a distal end of the piston rod, and a lower spring seat operatively coupled to the housing. The upper and lower spring seats capture the coil spring therebetween. The lower spring seat has a base portion having an opening for receiving the housing and is fixedly securable to the housing. A generally circumferential wall portion extends from the base portion and forms a catcher for catching a broken portion of the coil spring if the coil spring fractures. An impact absorbing structure is formed on the lower spring seat adjacent both of the catcher and the base portion, and is configured to be crushed in the event of a fracture of the coil spring.
