REMOVABLE NOZZLE ASSEMBLY.

摘要

A seal assembly having a first seal member made of a deformable material which maintains its deformed configuration after release of the deforming force. The seal in a preformed condition is placed around the rear end of a retaining insert, with a nozzle element also being placed within the seal member. The assembled components are inserted in the discharge end of a high pressure housing which is then pressurized to cause the seal material to deform into sealing of engagement and also to grip the insert and the nozzle element to form a unitary nozzle assembly which can easily be removed from the housing.
