ABSTRACT:
A regulated flow restrictor device particularly useful as a drip irrigation emitter includes a housing having a a flow-restrictor passageway formed with baffles defining clearances with the passageway walls, which clearances, by the displacement of a deformable elastomeric membrane, regulate the fluid flow through the passageway in response to variations in the pressure of the fluid. The clearances are of increasing height from one end of the passageway towards the other end such that the clearances are sequentially closed with increasing pressure at the housing inlet to maintain a substantially uniform flow through the housing outlet despite variations in the inlet pressure.
