Abstract
An exemplary embodiment of a combination valve assembly comprises a valve housing, an overpressure vent valve, a fill valve and a movable liquid overfill seal. The valve housing includes a longitudinal axis. The overpressure vent valve relieves excess pressure from the tank to which the assembly is affixed. The fill valve includes a fill valve pin actuatable between an open and closed configuration. The overfill seal is movable between a fluid sealing position and a fluid releasing position, and is elastically biased toward its fluid sealing position. In its fluid sealing position, the overfill seal prevents liquid from escaping the tank through the dip tube and outward of the valve assembly. Actuation of the fill valve pin toward its open position and movement of the overfill seal toward its fluid releasing position are preferably configured to both occur in the same direction, which is substantially parallel to the longitudinal axis.
