Abstract
The plunger is provided for use in a nozzle assembly which includes an internal chamber with an outwardly tapered portion at one end thereof; the plunger includes plurality of outwardly curved prongs or legs which mate with an inwardly tapered portion of the internal chamber in order to allow the piston of the injector to be released from the plunger; the plunger may be removed from the injector when the nozzle assembly is removed therefrom; the plunger includes a frangible portion that, upon firing, its first driving member breaks away from its second driving member; the frangible connection prevents reuse of the nozzle assembly as the first driving member remains lodged in a distal portion of the chamber.
