Atomising nozzle and filter and spray generating device

摘要

The present invention provides a simple form of nozzle assembly for use in generating sprays from a fluid, which comprises a plate 1 having grooves 2 leading to the edge and another plate 10 which lies on plate 1, co-operating with it so that the grooves become liquid conduits. As shown, grooves 2 converge so that issuing liquid jets impinge on each other. Other configurations are illustrated. Other, preferably smaller, grooves 3 link inlet 4 with plenum 5 from which grooves 2 run. These grooves 3 act as filters so that the liquid, which in use passes up spigot 21 to aperture 10 and inlet 4 is freed from solids before it reaches grooves 2.
