Abstract
A spray nozzle assembly (10) comprising a cap (30) which houses an inner assembly of nozzle inserts (40). The cap (30) is threadably engaged by complementary threads (31, 21) to a nozzle body (20). The nozzle body (20) and the cap (30) are therefore able to be mated in a controllable axially compressive relationship in which the threadable connection enables a large amount of finely controlled axial tensile or compressive force to be applied in either moving the cap (30) and nozzle body towards each other or away. It should be noted, however, that seat (70) restrict the extent of axial travel of the screwable parts (20, 30, 40) relative to and towards each other. This facility enables strong unwanted adhesive forces of glue-like or set flowable material to be broken so that the cap (30), insert assembly (40) and nozzle body (20) can be moved apart for servicing.
