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.

A gas treatment system comprises a variable flow regulator assembly placed in operable and fluid communication with a shell of a gas treatment device. The variable flow regulator assembly comprises two or more conduit portions comprising a first portion and a second portion, wherein the second portion has a coefficient of thermal expansion greater than a first coefficient of thermal expansion of the first portion. The variable flow regulator assembly structurally changes shape to alter the flow maldistribution of an exhaust gas stream into the gas treatment device when light off is achieved.

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.

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. The strut expands and collapses during pressure and vacuum cycles in the tank body. The coupling means limits linear collapse and expansion of the strut to prevent excessive collapse and expansion of the tank body.
