Abstract
Abstract A liquid spray nozzle consists of a tubular body closed at one end by an end wall. The end wall is formed with an internal annular groove defining an island through which a diametral drilling is formed. A slot in the external surface of the end wall intersects the drilling. The nozzle assembly also includes an air casing which defines air nozzles positioned to create a flat fan-shaped airflow pattern enclosing the flat fan-shaped liquid spray pattern produced by the nozzle assembly.
