Abstract
An air atomizing liquid spray nozzle is characterized by a body having a generally elliptical outlet end defining a generally elliptical liquid outlet orifice and an air cap having a generally elliptical air outlet aperture concentric with and surrounding the elliptical outlet end of the body for causing a complementary annular elliptical pattern of compressed air to concentrically surround and impinge upon liquid flowing in an elliptical pattern from the outlet orifice and to directly atomize the liquid into a flat, fan-shaped spray pattern with reduced consumption of air and less noise than prior art nozzles.
