Example of a siphon that uses only atmospheric pressure to raise the liquid up during the entire siphoning process without any contribution from liquid tensile strength.

Siphon principle In the flying-droplet siphon, surface tension pulls the stream of liquid into separate droplets inside of a sealed air-filled chamber, preventing the liquid going down from having contact with the liquid going up, and thereby preventing liquid tensile strength from pulling the liquid up. It also demonstrates that the effect of ...
Droplet formation using a flow focusing device. [17] Diagram of flow focusing droplet formation device commonly used in microfluidic devices. Liquid flowing in from the left is pinched off into droplets by an oil flowing in from the top and bottom. [10] Two stream reagent addition using a flow focusing approach with a planar chip format.

This type of spray nozzle may require more atomizing air and a higher atomizing air pressure drop because the mixing and atomization of liquid takes place outside the nozzle. The liquid pressure drop is lower for this type of nozzle, sometimes drawing liquid into the nozzle due to the suction caused by the atomizing air nozzles (siphon nozzle).

The design was first reported by McCarthy (1934). [2] As shown in the diagram, a stoppered reservoir is supplied with an air inlet and a siphon.The pressure at the bottom of the air inlet is always the same as the pressure outside the reservoir, i.e. the atmospheric pressure.
A perforated disc (4) covered by a flexible plate or flap (5) is joined by the siphon rod (6) to the flush lever. Pressing the lever raises the plate, forces water over the top of the siphon into the vertical pipe, and starts the siphonic discharge. Water flows past the flap until the cistern is empty, air enters the siphon and the flush stops.
