Abstract
A fuel dispensing nozzle includes a nozzle body defining a fuel supply passage in which a main control valve is operated by a hand actuated lever pivotally connected to an automatic shut-off mechanism. A protective guard member encloses the lever, and a trigger member is pivotally connected to the lever for manual movement to engage a stop supported by the guard member. A torsion wire coil spring includes a plurality of helical turns surrounding the pivot pin for the trigger member and has one projecting end portion engaging the lever and an opposite end portion biasing the trigger member.
