A self priming siphon device having a pilot siphon tube which discharges into a priming chamber thereby creating a partial vacuum within the priming chamber sufficient to cause flow through additional auxiliary siphon tubes. The partial vacuum is produced by liquid flowing from the priming chamber through priming tubes to a discharge point.
Claims9
A self priming siphon comprising a pilot siphon tube and a plurality of auxiliary siphon tubes communicating in an arcuate path between a lower level of a liquid holding vessel and the top of a priming chamber and a plurality of downwardly extending priming tubes communicating between the bottom of the priming chamber and the atmosphere, the apex of said pilot siphon tube being disposed at a lower elevation relative to the liquid level in said vessel than the apices of said auxiliary siphon tubes and the internal diameter of said pilot siphon tube and said priming tubes being equal to or less than the maximum diameter which results in the liquid forming droplets which bridge and plug the interior of said tubes.
