Fluidic pumping system

Creators

Description

A fluidic pumping system comprises a venturi-like ''reverse flow diverter'' positioned below the level of a liquid to be pumped and inserted between a charge vessel and a delivery pipe. A control system including pressure-responsive devices effects alternate pressurising and venting of the charge vessel, this cycle in effect pumping the liquid into a line. The pressure-responsive devices react to the pressure changes which occur when the air/liquid interface reaches junctions with pipes, electric output signals then causing vessel to be pressurised or vented accordingly to continue the cycle.
