Patent ID: 7083120

Claim:
A pressurized fluid delivery apparatus, comprising: a pump adapted to provide a pressurized fluid; a conduit that receives the pressurized fluid pressurized by the pump; a fluid accessory fluidly connected with the conduit to receive the pressurized fluid from the conduit, the fluid accessory including a nozzle assembly configured to discharge the pressurized fluid with a spray pattern; an adjustable mechanism configured to widen and narrow the spray pattern; a housing rotatable relative to the nozzle assembly and operably coupled to the adjustable mechanism, the housing being rotatable relative to the nozzle assembly in a first direction, in which the spray pattern of the pressurized fluid is widened, and a second direction, in which the spray pattern of the pressurized fluid is narrowed; and a quick-disconnect assembly selectively fluidly connecting the nozzle assembly and the conduit, the quick-disconnect assembly including a male fitting coupled to one of the nozzle assembly and the conduit, the male fitting including a male component; a first non-circular surface; a female fitting coupled to the other of the nozzle assembly and the conduit, the female fitting including a female component having an opening for receiving the male component; and a second non-circular surface coupled to the first non-circular surface to prevent rotation between the male fitting and the female fitting when the housing is rotated relative to the nozzle assembly.
