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.
Claims22
A one-way valve assembly for a fuel tank filler neck comprising:
- (a) a tubular shell having a valve seating surface formed about one end thereof and having a reduced exterior diameter portion on the end opposite said one end and adapted for insertion in the end of an existing filler neck and having a recess formed therein adjacent said one end;
- (b) a moveable valve member hingedly disposed for movement with respect to said one end of said tubular shell;
- (c) a spring disposed to have one end thereof contacting said recess in said shell and having the end opposite said one end secured to said valve member, wherein said spring is operative to bias and maintain said valve member into contact with said valve seating surface;
- and,
- (d) a flexible annular seal disposed to seal between said valve member and said valve seating surface.

A method of installing a filler tube on a metal fuel tank comprising:
- (a) providing a tubular metal filler neck with an annular flange on the outer periphery thereof;
- (b) inserting a one-way valve on a proximal end of the filler neck and inserting an end of the filler neck distal the proximal end in a proximal end of a flexible tube;
- (c) inserting a tubular nozzle receiver in an end of the flexible tube distal the proximal end and forming a filler neck subassembly;
- and,
- (d) inserting the one-way valve of the subassembly in an access opening in the tank and securing the annular flange of the filler neck about the access opening thereby retaining the subassembly on the tank.

A method of installing a filler tube on a plastic fuel tank comprising:
- (a) providing a tubular plastic member with an annular flange on the outer periphery thereof;
- (b) inserting a one-way valve in a proximal end of the tubular member;
- (c) inserting an end of the tubular member distal the proximal end in one end of a flexible filler neck and inserting a tubular nozzle receiver in an end of the filler neck distal the one end and forming a filler tube subassembly;
- and,
- (d) inserting the one-way valve of said subassembly in an access opening in the tank and securing the annular flange to the tank about the access opening and retaining the subassembly on the tank.
