ABSTRACT:
A liquid atomizing and spraying device which can be operated with a relatively low air pressure. The spraying device has three coaxial tubular passages; an inner one for air, an intermediate one for liquid, and an outer one for air; which are shaped to have the liquid ejected as a thin film having a divergently conical shape which is caused to vibrate by the air which is being ejected in a vortex flow for generating cusps on the film in an electrostatic field for being finely atomized and projected.
