Abstract: A damper includes a pressure tube and a piston. The piston defines a rebound chamber and a compression chamber. The damper further includes a piston rod that reciprocates with the piston. The damper includes a sealing ring slidably disposed around the piston rod. The sealing ring includes a locking mechanism adapted to lock the sealing ring around the piston rod. The sealing ring also includes an inner surface having a plurality of concave surfaces and a plurality of convex surfaces. Each of the plurality of concave surfaces is located adjacent to a corresponding convex surface of the plurality of convex surfaces. The sealing ring further includes an upper surface extending between the outer and inner surfaces. The upper surface defines a plurality of channels. The sealing ring further includes grooves and bleeds for tuning energy dissipated by the damper during rebound stroke to help reduction of noise.

Abstract: A damper valve assembly for an exhaust system of a vehicle includes a valve housing and a valve flap. The valve housing is adapted to be attached to a pipe of the exhaust system and defines an opening. The valve flap is rotatable relative to the valve housing and about a pivot axis between a first position whereat fluid flow through the opening of the valve housing is restricted and a second position whereat fluid flow through the opening of the valve housing is allowed. The valve flap includes a body and a mass damper. The mass damper is integral with the body and includes a plurality of segments that are folded so that the plurality of segments are in a stacked arrangement.

Abstract: A mixer assembly for mixing an injected reductant with an exhaust gas output from a combustion engine comprises a mixer housing including a wall defining an exhaust passageway having a longitudinal axis. A tubular swirling device housing extends along a first axis substantially transverse to the longitudinal axis. The tubular swirling device includes a plurality of openings through which exhaust gas enters. The exhaust gas within the tubular swirling device swirls about the first axis and exits at an outlet end of the tubular swirling device. A mixing plate is positioned immediately downstream of the tubular swirling device. The mixing plate swirls the exhaust about a second axis extending parallel to the longitudinal axis.

Abstract: A damper system for a vehicle is provided that includes an outer tube, a piston rod, and a piston assembly that is mounted to the piston rod and separates the outer tube into first and second working chambers. A valve assembly, mounted to the piston assembly, controls fluid flow between the first and second working chambers. A magnetic rotor is fixed to and extends annularly about the outer tube. A stator assembly is coupled to the piston rod by a spherical bearing assembly. The stator assembly includes a plurality of coils that apply an active damping force to the piston rod when energized. The coils can also generate electricity from axial movements of the piston rod relative to the outer tube. One or more glide bearings are disposed radially between the coils and the magnetic rotor in a sliding fit to stabilize the stator assembly.

Abstract: An exhaust gas heat recovery system includes a housing, a heat exchanger and a valve assembly. The valve assembly is disposed within the housing and includes a monolithic valve body, a moveable valve plate and a rotatable valve shaft. The valve body includes a bore, a valve seat surrounding the bore and trunnions integrally formed with the valve seat. The trunnions are diametrically opposed to each other and laterally extending outside of the housing. The valve plate coupled for rotation with the valve shaft between a first position allowing exhaust gas flow through the bore and the first exhaust gas passageway, and a second position allowing exhaust gas flow through the second exhaust gas passageway and preventing exhaust gas flow through the bore and the first exhaust gas passageway. The valve shaft being supported for rotation by the trunnions.

Abstract: An exhaust gas heat recovery system includes a housing assembly, a valve assembly and a heat exchanger. The valve assembly is disposed within the housing assembly and includes a shaft and a plate. The plate is rotatable between a first position whereat exhaust gas flow through a first fluid passageway is allowed and exhaust gas flow through a second exhaust gas passageway is prevented, and a second position whereat exhaust gas flow through the second fluid passageway is allowed and exhaust gas flow through the first gas passageway is prevented. The heat exchanger assembly includes a heater core having a working fluid circulating therein. The working fluid is in thermal communication with fluid in the heater core. The housing assembly includes first and second shells attached to each other at a joint. An axis of the shaft being at the joint of the first and second shells.
