Abstract: Disclosed herein are liquid containment systems, methods for making such systems, and vehicle fuel storage systems having vapor recirculation capabilities. Presented is a liquid containment system for stowing hydrocarbon-based liquids. This system includes a vapor canister coupled to a liquid container to receive hydrocarbon vapor from the container. A fill conduit coupled to the container has an opening for receiving a fill nozzle. A vapor recirculation transmits vapor from the container to the fill conduit. A multi-stage check valve, which is coupled to the container and recirculation conduit, has a housing and a plunger with a bleed hole. The plunger seats against the housing such that vapor passes from the container through the bleed hole to the fill conduit via the recirculation conduit. Responsive to increased in-tank pressure, the plunger unseats from the housing such that vapor passes through the bleed hole and around the plunger to the fill conduit.

Abstract: A throttle valve assembly for an internal combustion engine includes a throttle body having a bore formed therein and a sidewall having a throttle shaft opening formed therethrough. A throttle shaft passes through the throttle shaft opening and includes a shaped end. A disc shaped retainer is positioned within the opening and has a corresponding shaped opening for receiving the shaped end of the throttle shaft. When the shape end of the throttle shaft passes through the shaped end of shaped opening of the retainer, the throttle shaft is rotated relative to the retainer to create an interference engagement therewith so as to retain the throttle shaft within the throttle body to limit axial displacement thereof.
