Abstract: A rotational speed damper operable to dampen the speed of a gear by gradually decreasing the rotational velocity and angular acceleration of the gear over a time period beginning at the time the damper contacts the gear stop and ending at the time the gear reaches its first stopping point.

Abstract: A pintle bushing assembly for a poppet valve assembly including a tolerance ring which is disposable between the pintle bushing and a bore in the body of the valve to both seal and center the bushing in the bore. The tolerance ring includes a plurality of radially-extending dimples which are deformable during assembly such that the valve pintle can be aligned coaxially with the valve seat under all conditions. An axial flange on the tolerance ring is sealed against axial surfaces of the valve body adjacent the bore and a flange on the bushing to prevent leakage past the bushing.

Abstract: A fuel pressure regulator assembly for a fuel delivery module of a fuel system of a vehicle includes a housing having a cavity therein and a valve seat extending into the cavity and a passageway extending through the valve seat. The fuel pressure regulator assembly also includes a movable piston disposed in the cavity of the housing and a seal connected to the piston and disposed between the piston and the valve seat. The fuel pressure regulator assembly further includes a biasing mechanism disposed in the cavity to bias the piston and the seal toward the valve seat to close the passageway.

Abstract: The gas sensor comprises a sensor element; a shell disposed around at least a portion of the sensor element, the shell having a projecting edge from a first end, wherein a portion of the projecting edge is bent toward the sensing element; an upper shield disposed around at least a portion of the sensor element, the upper shield having a terminal end; a gasket disposed between the projecting edge and the terminal end, wherein the gasket is a U-type gasket; and a lower shield affixed to a second end of the shell.

Abstract: A plastic fuel tank including a hollow plastic tank body and a variable length plastic strut in the hollow tank body. A pair of flat plastic sheets are vacuum formed at a forming temperature in upper and lower mold cavities to the shape of upper and lower plastic shells. The plastic strut includes an upper foot, a lower foot, and a coupling means operable to support the upper foot on the lower foot for back and forth linear translation against a controlled resistance. With the mold cavities separated, the plastic strut is interposed between the upper and lower shells. The mold cavities are closed to form the hollow tank body by fusion bonding the upper and lower shells at respective attachment flanges on each. When the tank body thereafter cures and shrinks, the plastic strut is squeezed between the upper and lower shells against the controlled resistance of the coupling means to fusion bond the upper and lower feet of the strut to the shells.
