Gas-assisted atomizing devices and methods of making gas-assisted atomizing devices

A method of forming a gas-assisted atomizing device, comprising the steps of:

• forming a substantially planar first and second layers;
• forming a gas supply network and a liquid supply network in the substantially planar first layer and the substantially planar second layer;
• forming a plurality of orifices in the second layer;
• and
• connecting the gas and liquid supply networks to supply gas and liquid to the plurality of orifices to form an atomized spray at the plurality of orifices.

A method of forming an atomizing device, comprising the steps of:

• forming a first opening in a substantially planar first layer;
• forming a second opening in a substantially planar second layer, the second opening having at least one inner surface with an atomizing edge;
• forming a third opening in a substantially planar third layer;
• forming at least one liquid orifice in at least one of the first and second layers;
• and
• connecting the first and second layers such that the first and second openings are aligned to form a main gas orifice that guides a main gas in a flow direction and such that the at least one liquid orifice supplies liquid to be atomized onto at least one inner surface of the second opening;
• forming at least one auxiliary gas orifice in at least one of the second and third layers;
• and
• connecting the second and third layers such that the third opening is aligned with the first and second openings so as to form the main gas orifice and such that the auxiliary gas orifice supplies auxiliary gas to the atomizing edge of the at least one inner surface of the second opening.
