Abstract
A fuel filler tube assembly including a one-way valve or check valve. The tube assembly is adaptable for pre-assembly on either a metal or plastic fuel tank and employs a common check valve with an adapter tube for plastic tanks. The valve employs a flapper with spaced ribs for deflecting a siphon hose away from the valve seal; and, the ribs are spaced to maintain the flow stream of he fuel during refueling and facilitating opening of the flapper.
Claims17
A one-way valve assembly for connecting with a fuel tank filler neck comprising:
- a tubular shell with a valve seating surface disposed about one end thereof with a reduced diameter exterior portion on an end opposite said one end adapted for insertion in the end of an existing filler neck;
- and
- a moveable valve member disposed for movement between a position closing on said valve seat and a position away from said valve seat with a plurality of spaced ribs disposed thereon operable for minimizing dispersion of the flow stream during refueling through the fuel tank filler neck with respect to said one end of said tubular shell and operable to prevent a siphon hose from catching on the valve member, wherein the valve member is biased into contact with said valve seating surface,
- wherein said tubular shell and said valve member are formed of plastic material and wherein said plastic material is interspersed with electrically conductive material for facilitating discharge of accumulated static electrical charge.
A one-way valve assembly for connecting with a fuel tank filler neck comprising:
- a tubular shell with a valve seating surface disposed about one end thereof with a reduced diameter exterior portion on an end opposite said one end adapted for insertion in the end of an existing filler neck;
- and
- a moveable valve member disposed for movement between a position closing on said valve seat and a position away from said valve seat with a plurality of spaced ribs disposed thereon operable for minimizing dispersion of the flow stream during refueling through the fuel tank filler neck with respect to said one end of said tubular shell and operable to prevent a siphon hose from catching on the valve member, wherein the valve member is biased into contact with said valve seating surface,
- wherein said valve member includes a pair of arms extending therefrom with end portions thereof pivotally engaging said tubular shell and wherein said pair of arms are deflected when attached to the tubular shell.
A one-way valve assembly for connecting with a fuel tank filler neck comprising:
- a tubular shell with a valve seating surface disposed about one end thereof with a reduced diameter exterior portion on an end opposite said one end adapted for insertion in the end of an existing filler neck;
- and
- a moveable valve member disposed for movement between a position closing on said valve seat and a position away from said valve seat with a plurality of spaced ribs disposed thereon operable for minimizing dispersion of the flow stream during refueling through the fuel tank filler neck with respect to said one end of said tubular shell and operable to prevent a siphon hose from catching on the valve member, wherein the valve member is biased into contact with said valve seating surface, wherein said tubular shell has a slot formed thereon with portions of said valve member received therein and permitting axial movement for facilitating seating of said valve member on said opposite end of said tubular shell.
