Abstract:
1. A fuel storage assembly for containing fuel and allowing pressurized fluid to vent out from the assembly when the pressure within the assembly exceeds a selected level that is greater than the pressure outside the assembly, said assembly comprising: a tank configured to hold a liquid fuel, said tank being substantially sealed and presenting an opening through which pressurized fluid can vent from inside the tank to outside the tank, said tank including an internally threaded flange around the opening; a generally annular vent body presenting an axially proximal margin and an axially distal margin, said axially proximal margin being threadably received within the flange of the tank, said vent body defining a generally cylindrical chamber, said vent body including a supporting crossbar generally radially spanning the chamber; a lid generally axially surmounting the axially distal margin of the vent body; a rod projecting axially proximally from the lid, said supporting crossbar including a generally centrally disposed hole defined axially therethrough, said rod projecting through the hole in the crossbar such that the crossbar radially supports and axially aligns the rod, said crossbar including an axially distal portion that is generally coplanar with the axially distal margin of the vent body, said cylindrical chamber including a widening bore having a cross-sectional dimension that progressively increases distally, said crossbar projecting across and being located within the widening bore so as not to project proximally beyond the widening bore; and a spring retained between the rod and crossbar so as to yieldably urge the lid into a closed position, said spring extending axially at least to the widening bore.
