Summary for Patent: 5,472,143

Title: Atomising nozzle and filter and spray generation device
Abstract:A nozzle assembly for use in atomizing and generating sprays from a fluid. The nozzle assembly includes two members joined together. In one of the two members are formed one or more nozzle outlets, one or more fluid inlets, and a plurality of channels that form filter passageways.
