Dispensing tool assembly for a fluid fill tube
First Claim
1. A fluid dispensing tool assembly adapted for connecting a fuel supply line to a fill tube extending from a fuel tank, said assembly comprising a body defining a fluid supply passage having a fluid actuated control valve and extending to an outlet tube having an axis, a set of arcuate clamping jaws surrounding said outlet tube, an annular fluid actuated clamping piston surrounding said outlet tube and effective to expand said clamping jaws outwardly into engagement with an inner surface of said fill tube in response to axial movement of said clamping piston, an annular sealing piston surrounding said clamping piston and effective to move a sealing ring into substantially fluid-tight sealing engagement with said fill tube in response to axial movement of said sealing piston after said fill tube is clamped, fluid actuating passages within said body and extending to said control valve, said clamping piston and said sealing piston, and connectors adapted to connect said fluid actuating passages to corresponding flexible fluid actuating lines.

Abstract
Fuel is dispensed into a fuel tank fill tube by a hand-held tool assembly having a body with an outlet tube connected to a fuel supply passage through an air actuated control valve. Spring biased arcuate jaws surround the outlet tube and expand outwardly into engagement with an inner surface of the fill tube by an air actuated annular clamping piston surrounding the outlet tube. An air actuated annular sealing piston surrounds the clamping piston and is effective to seal the outer end of the fill tube after the fill tube is clamped. The position of the fill tube is sensed by a pin which actuates a proximity switch, and a handle and fluid line connectors projecting from the body at right angles to the outlet tube. Thumb operated control switches are located adjacent the handle.
