Abstract
Abstract An atomizer for liquids of the type utilizing atomization by a gas is provided with at least two channels which terminate at the head of the atomizer and which communicate with a common supply for the gas. The channels pass through a common, bounded space and at the location of the intersections around their entire circumference communicate with that space. The bounded space communicates with a supply for the liquid.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
178 words
An atomizer for liquids comprising: an atomizer head having a plurality of fluid outlets for atomized liquid therein; at least two channels within the atomizer, each channel terminating at an outlet in the atomizer head and being in fluid communication with a common gas supply channel; the atomizer head having a bounded space therein in fluid communication with a supply of liquid to be atomized; the channels intersecting and passing through said bounded space, the section of each channel between the bounded space and the outlet of the atomizer being of a larger diameter than the section of each channel between the bounded space and the common gas supply channel; and each of the channels communicating with the bounded space around the entire perimeter of the channel at the location of the intersection of the channel with the bounded space; whereby gas flowing from the common gas supply passes into the channels, contacts and atomizes liquid at the intersection of the channels with the bounded space, and carries atomized liquid further down the channels to the fluid outlets.
Claim 2
Dependent Claim
