Abstract
A quick disconnect nozzle assembly comprising a nozzle body, a spray tip, and an annular sealing member interposed therebetween. The nozzle body and spray tip have inclined seal engaging surfaces that compress the annular sealing member at three distinct points for exerting both axial and radial pressures thereon, and the body and spray tip have cams and separate radial detents for smoothly drawing the tip and body together into sealing engagement with the annular sealing member in repsonse to tip rotation and without the necessity for overcompressing the sealing member. A secondary, external sealing member is provided, which together with the internal sealing member, seal the cams and detents in an internal chamber area isolated from the liquid sprayed by the nozzle.
