ABSTRACT:
A nozzle for applying a quasi-random splatter pattern of viscous fluid material. The nozzle includes an axially inward gas flow path and an axially outward material flow path. The material flow paths are partially defined by an array of material flow passageways that are yieldingly obstructed by a valve member. The valve member has a center bore to permit passage of a stream of gas. Pressurization of the viscous fluid material causes the material to exceed the threshold pressure for axial movement of the valve member. The viscous fluid material will thereafter flow to an outlet orifice having a configuration which is at least closely similar to the array of material flow passageways. Material at the outlet orifice is impinged by the stream of gas through the nozzle for projection to a surface.
