Latest Patents
One of Clark's latest patents is a fuel filling assembly designed for liquid fuel tanks, especially on boats. This assembly includes a fill tube that can be mounted through a deck, along with a closure cap that is preferably hinged over the fill tube opening for selective opening and closing. A positioning member allows the closure cap to be mounted in various positions relative to the fill tube, accommodating different mounting locations on a boat. The fill tube can be either angled or straight to further adapt to varied mounting positions. In one version, a separate vent tube connects to the fill tube, providing continuous fuel tank venting, pressure equalization, and a return of fuel overflow to the tank in case of overfill. The vented version features a rigid shield on the closure cap that extends over the opening to a vent passageway, restricting the escape of liquid fuel during extreme boat movements. The design also includes a tortuous vent passageway to prevent the ingestion of water or contaminants, along with a baffle to prevent fuel expulsion during tank filling.
