Abstract
A quick disconnect nozzle assembly having a nozzle body, an annular sealing member and a nozzle tip with a socket in the body for receiving the tip and having a pair of chord-like lugs with upstream facing camming surfaces for engaging downstream facing camming recesses in a pair of radially extending shoulders on the nozzle tip to cam the tip axially into sealing engagement with the annular sealing member as the nozzle tip is inserted in the socket and rotated therein. Preferably the socket includes diametrically opposed lugs and the tip has a pair of cooperating shoulders and recesses and at least one radially extending stop adapted to engage an abutment in the base of the socket when the tip is rotated into proper position. The tip may include a swirl imparting vane and have an outer protective sleeve with longitudinal ribs to facilitate rotating the tip by hand.
