Abstract
A system for dispensing fuel, a hose assembly therefor and methods of making the same are provided, the hose assembly having a spider to maintain the inner hose thereof concentric within the outer hose thereof, the spider being secured to the inner hose and to the dispensing nozzle so that the nozzle, the spider and the inner hose are adapted to rotate in unison relative to the liquid fuel source unit of the system whereby a tubular unit interconnected to a venturi unit in the nozzle and leading to a drape area within the hose assembly for evacuating any liquid collecting in the vapor recovery passage thereof will also rotate in unison with the nozzle, the spider and the inner hose.
Claims9
In a spider means for a hose assembly for a system comprising a liquid fuel source unit, a dispensing nozzle, and said hose assembly, said hose assembly having a first fluid passage therein for conveying said liquid fuel in one direction from said liquid fuel source unit to said nozzle that is adapted to dispense said liquid fuel into a container and a second fluid passage therein for returning the vapors of said liquid fuel from said container to said liquid fuel source unit, said hose assembly comprising a flexible inner hose having an outer peripheral surface and defining said first fluid passage therein, said inner hose having a coupling comprising an insert portion attached to one end of said inner hose, and a flexible outer hose having an inner peripheral surface and being disposed around said inner hose, said inner peripheral surface of said outer hose and said outer peripheral surface of said inner hose defining said second fluid passage therebetween, said nozzle having a venturi section therein that tends to remove liquid from a drape area of said hose assembly when said nozzle is being utilized to dispense said liquid fuel into said container, said hose assembly having opposite ends one of which is adapted to be interconnected to said nozzle and the other of which is adapted to be interconnected to said liquid fuel source unit, said one end of said hose assembly having said spider means therein that tends to maintain said inner hose concentric within said outer hose, said spider means having a passage means therethrough, said hose assembly comprising a first tube section for connecting said passage means to said venturi section and a second tube section connected to said passage means and having inlet means located in said drape area, the improvement wherein said spider means is mounted on said coupling and has a first means adapted to be received in said insert portion of said coupling to prohibit rotational movement of said spider means relative to said coupling and has a second means adapted to be secured to said nozzle wherein said coupling, first means and second means cooperate so that said nozzle, said spider means and said inner hose are adapted to rotate in unison relative to said liquid fuel source unit.
