Abstract
An alignable conformal, cup-shaped flag-mushroom fluidic nozzle assembly is engineered to generate a flat fan or sheet oscillating spray of viscous fluid product 316. The nozzle assembly includes a cylindrical flag mushroom fluidic cup member 180 having a substantially closed distal end wall with a centrally located snout defined therein. The flag mushroom cup assembly effectively splits the operating features of the fluidic circuit between a lower or proximal portion formed in the housing's sealing post member and an upper, or distal portion formed in cup member 180 which, in cooperation with the sealing post's distal surface, defines an interaction chamber 192 fed by impinging jets each comprising a continuous distribution of streamlines that impinge at selected angles to define arcs providing a lesser degree of impingement at a centered axial plane within the exit orifice 194 and a greater degree of impingement at the edges of exit orifice 194.
