<p>A self-compensated, adjustable fluid emitter includes 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 communicates with the first chamber and an outlet communicating with the second chamber, causing the first and the second chambers to be in communication one with the other through a communicating duct. In operation, the membrane becomes deformed such that at least a portion thereof changes its position with respect to the outlet, modifying the flow rate of the fluid through the outlet depending on the pressure difference. Therefore, the flow rate of the fluid through the outlet is controlled and kept constant by the membrane in spite of changes in fluid pressure at least at the inlet or the outlet.</p> |
