SELFCOMPENSATED ADJUSTABLE FLUID EMITTER, PARTICULARLY IN IRRIGATION SYSTEMS.

摘要

A selfcompensated, Adjustable fluid emitter comprising a casing externally delimiting a volume which is divided into a first chamber and into a second chamber by a fixed membrane that can be elastically deformed; an inlet communicating with said first chamber; an outlet communicating with said second chamber; said first and said second chamber being in communication one with the other by means of at least a communicating duct; said membrane being deformed such that at least a portion thereof changes its position with respect to said outlet, modifying the flow rate of the fluid through said outlet depending on the pressure difference and so on the flow rate of the fluid through said outlet is controlled and kept constant by said membrane in spite of changes in the fluid pressure at least at the inlet or outlet.
