Title: Fluid dispensing nozzle including trigger retaining mechanism

Abstract: A fluid dispensing nozzle, e.g., a nozzle for a gasoline station filling pump, is provided with a trigger retaining mechanism which allows an operator to retain the nozzle trigger member in its operative position by exerting a continuous relatively low manual force in contrast to the relatively high manual force required to operate the trigger member. The trigger member automatically returns to its inoperative position immediately upon release of the manual force on the trigger retaining mechanism. The fluid dispensing nozzle is particularly suitable for use in self-service gasoline filling stations.
