Abstract
The invention comprises a quick disconnect nozzle including a nozzle body and a nozzle tip, wherein the nozzle body may be connected to a source of fluid and the nozzle tip is separable from the body by a single twist type action, yet the nozzle may be securely locked in the body by an interlocking engagement between the nozzle and body that is engaged and disengaged by relative twisting of the two parts. The locking action is obtained by the engagement of cooperative elements on the two parts including oppositely disposed undercut shoulders on the nozzle body and a pair of rounded projections on the nozzle tip which are engaged under the opposing shoulders by the relative twisting action. The interlocked relationship is maintained by a combination sealing member and pressure device that effectively seals the connection between the nozzle body and tip and exerts pressure therebetween to secure the locked connection.
