Abstract
A fuel system ullage float valve assembly is provided for fuel tank and fuel fill line. This assembly is located near the intersection of the fuel fill line entering the uppermost top section of a fuel tank. A ullage float valve assembly includes a cage enclosure having an upper collar, a plurality of leg members and a base, essentially forming a frame-like structure. The upper collar is partially inserted into, and nest within, the fuel fill line as it enters the tank. The leg members extend downwardly into the tank in a generally vertical position. The assembly also includes a buoyant float chamber, having a generally cylindrical base and a generally converging, conical upper section. The float chamber is buoyant and it housed within the cage enclosure, and is slididly movable within the enclosure. During the fueling process as fuel fills the tank the ullage float assembly rises within the cage enclosure and to reach a sealing engagement with the upper collar of the assembly causing termination of the fueling process. The float assembly also includes a fuel bypass port.
