Abstract
A fully-integrated flow-control valve assembly for top-filled fuel tanks incorporates both a float valve assembly and a shut-off valve assembly in a single unit that screws into a threaded aperture in the top of the fuel tank. Whereas all other systems having similar function rely on an inlet valve and a level control/vent positioned apart from one another and intercoupled with a bleed line that runs either inside or outside the fuel tank, the device of the present invention directly mounts the two devices together and allows a simple installation. There is no need for a line that couples two remotely positioned units of the prior art flow-control assemblies.
Claims2
A fully-integrated flow-control valve assembly for top-filled fuel tanks comprising:
- a float valve assembly;
- and
- a shut-off valve assembly in a single unit that screws into a threaded aperture in a top of a fuel tank.
A fully-integrated flow-control valve assembly comprising:
- an inlet/vent head;
- an inlet/vent body secured to the inlet/vent head;
- an inlet drop tube secured to the inlet/vent body;
- a bleed body secured to the inlet drop tube;
- an inlet body secured to the bleed body 105;
- an inlet piston housed within the inlet body;
- a sealing sleeve fitted between the inlet piston and the inlet body;
- an inlet cap;
- and
- a spring positioned between the inlet cap and the inlet piston;
- wherein the force of the spring is sufficient to shut off fuel flow when a bleed path is shut by a float valve.
