Granted: 1991-06-11
Abstract: Abstract of the Disclosure A tension actuated fuel (e.g. gasoline) delivery hose uncoupler is disclosed in which, upon a predetermined tension load being applied to the delivery pump hose, the coupling will automatically uncouple thus releasing one end of the hose which, for example, may remain inserted in the fuel tank of a vehicle driving away from the fuel dispensing pump, and the other portion of the hose which is permanently affixed to the pump.  The coupler includes normally closed check valves which, upon uncoupling of the coupler, close thereby preventing spillage of fuel.  Further, the coupler is adjustable so that it may be calibrated to uncouple at predetermined tension loads.  The uncoupler is structured so as to substanially eliminate the effects of fluid (e.g., gasoline) delivery pressure on the tension load required for uncoupling.
