US Patent 11498828 Methods and systems for on demand fuel supply

A float probe configured to regulate fluid flow into a fluid container is disclosed. The float probe comprises an upper assembly having one or more outlets, a plurality of rods extending from the upper assembly to a lower assembly and a float assembly disposed between the upper assembly and the lower assembly. A first distal end of the rods is coupled to the upper assembly and a second distal end of the rods is coupled to the lower assembly. The rods extend along an outer surface of the float assembly and the float assembly is movable along the rods between a first position proximate to the upper assembly and a second position proximate to the lower assembly. The float assembly prevents fluid flow out of the outlets when disposed in the first position.
