Abstract: A vent valve assembly includes a first housing component, a second housing component, and a third housing component, as well as a first valve and a second valve. The first, second, and third housing components are configured to assemble together along one directional axis with the second housing component, the first valve and the second valve between the first and third housing components and with the second valve laterally-spaced from the first valve. The assembled first, second, and third housing components define a nonlinear vapor flow path that redirects vapor from the first valve to the second valve, thereby reducing an overall height of the vent valve assembly.

Abstract: A valve device for a fuel tank includes a float element accommodated vertically movably in a case. The float element has a seal member at an upper portion thereof. The fuel flowing into the case through the inflow portion rises the float element to seat the seal member on the vent valve port. A ventilation portion connecting between inside of the tank and inside of the case is formed at an upper face portion of the case positioned above a waterline of the float element when seated. The upper face portion of the float element positioned in close proximity to the upper face portion reduces the amount of ventilation through the ventilation portion when seated. The valve device for a fuel tank further includes a regulation portion at the upper face portion of the case in which the interval is constant between the upper face portion of the case and the upper face portion of the float element when seated.

Abstract: A gas fuel tank with an internal emission fuel system includes a fill-and-vent valve system inside the fuel tank that controls fuel vapor through an exterior carbon canister and prevents spit back. This inventive system prevents exposure of the carbon canister to liquid or fuel. The fill valve assembly has a nylon wedge float that causes the fuel fill nozzle to shut off once the liquid level seals the valve opening. The vent valve assembly also has a nylon wedge float that shuts off vapor once the liquid level seals the valve opening.
