Abstract: A rotary valve plate adapted for housing within a conduit employs a vibration absorbing bumper pad coupled to the valve plate at a surface thereof adapted to contact an inner surface of the conduit whenever the valve plate is rotated to a closed position. The bumper pad minimizes vibratory noise and improves the durability of the valve plate over extended periods of operation.

Abstract: A catalytic unit, a process for providing a support mat for the catalytic unit, and a process for assembling the catalytic unit are provided. An installed mat density for the support mat being calculated based upon a desired annular cross-sectional area of a gap between a catalyst carrier and a shell of the catalytic unit, with the support mat being sandwiched therebetween. The support mat for the catalytic unit can be provided by first slitting a bulk roll of support mat to form a plurality of end unit specific mat rolls. The support mat can be wrapped around the catalytic carrier to form multiple layers of support mat, with the support mat having beveled leading and trailing edges to reduce variation in material density in the layers of support mat overlying and underlying the leading trailing edges. The support mat can be free of any binder.

Abstract: A method and apparatus for assembling an exhaust treatment device such as a catalytic converter employs post calibration to achieve a desired bulk gap density of a support mat surrounding a substrate in the device housing. The mat is gauged under pressure to a thickness yielding the target bulk gap density and the pressure is saved for use in comprising the device housing against the mat after soft stuffing of the mat/substrate subassembly into the housing.

Abstract: A component for a vehicular exhaust pipe includes an upstream venturi forming portion for creating at least a partial vacuum interior to the component. A downstream diverter housing portion of the component has an inlet coupled to an outlet of the venturi portion. The diverter housing portion includes the diverter element positioned adjacent an output of the diverter housing portion for forcing axially central exhaust flow radially outward toward a wall of the diverter housing. The partial vacuum in the component device causes colder environmental ambient air to enter an inlet of the component. The diverter also creates a mixture of hot exhaust flow with the colder environmental air, resulting in a lower temperature of the exhaust gas exiting the component and substantial elimination of centrally disposed exhaust hot spots.

Abstract: A shock absorber includes an external valve which controls the damping characteristics of the shock absorber. The external valve controls the flow of fluid between the lower working chamber of the shock absorber and the reservoir chamber and between the upper working chamber of the shock absorber. The damping characteristics are dependent on the amount of current being applied to a solenoid valve which controls the movement of a plunger.

Abstract: A dual tube shock absorber includes a spool valve located between the upper working chamber and the reserve chamber. The spool valve moves with the piston rod to open and close a flow path between the upper working chamber and the reserve chamber. This provides a low damping characteristic for small movements of the piston rod which changes to a high damping characteristic for larger movement of the piston rod.

Abstract: A valve assembly progressively opens to provide a smooth transition from a closed position to an open position. The fluid pressure reacts against a valve plate in a non-symmetrical manner to progressively open the valve. The valve can include a plurality of varying sized fluid passages or valve lands can be positioned eccentrically to each other to provide a non-symmetrical pressure area.
