ABSTRACT:
The invention relates to a pressure fuel servicing nozzle for mating with a standardized aircraft fueling adapter having a cylindrical extension with a plurality of indexing notches and a plurality of radially extending lock tabs. The fuel nozzle includes a nozzle body having an outer surface and an interior passage. A collar assembly is rotatably supported upon the outer surface of the nozzle body. A plurality of locating pins having a rectangular cross-section extend outwardly from the bottom base of the nozzle body. The fuel nozzle is properly aligned onto the fueling adapter by fitting the locating pins in the indexing notches of the fueling adapter such that the two opposing side faces contact the surfaces of the indexing notches. The fuel servicing nozzle further includes an interlock plate biased toward an exterior of the nozzle body by a plurality of spaced springs. The interlock plate has a plurality of apertures through which the locating pins pass. When the fuel nozzle is in a disconnected condition with the fueling adapter, the interlock plate forms a mechanical interference between the plurality of locating pins and the inner surfaces of a bayonet ring such that the collar assembly is locked about the nozzle body. When the fuel nozzle is connected to the fueling adapter, the interlock plate is depressed and the mechanical interference is cleared such that the collar assembly is free to rotate about the nozzle body.
