ABSTRACT:
A nozzle assembly comprising a tubular sleeve, a nozzle and a nozzle body. The nozzle and nozzle body are held in an assembled relation with their bores aligned by the tubular sleeve which encircles them. The sleeve provides a seal between the nozzle assembly and the body into which the nozzzle assembly is mounted, and also provides a seal between the nozzle and nozzle body. During use, when under working pressure, the tubular sleeve tends to flow and move both downstream and radially, forming seals between the nozzle assembly and the body into which it is mounted; and between the nozzle and nozzle body, which seals tend to increase in effectiveness as the working pressure increases. In another form, the set screw has a chamfer which engages a corresponding circular corner of said body, preventing downstream flow of the sleeve therebetween.
