Abstract
A throttle valve assembly for controlling flow of air through a passage. A housing is provided having a straight flow passage extending therethrough. The housing also has a bore formed therein in intersecting relationship to the passage. A valve is movably positioned within the bore for adjustably restricting the flow of air through the passage. The valve includes an elastomeric sleeve coaxially aligned with and positioned within the bore and being axially movable therealong into a position wherein the sleeve means extends across the passage. Relatively movable abutments coact with the sleeve when the latter is in said position for resiliently deforming the sleeve into at least partial sealing engagement with the housing for restricting or preventing flow of air through the passage.
