Abstract:
1. A self-regulating mechanism for irrigation emitters, which being planned to allow an irrigation emitter to operate at specific fractions of the entire time commanded by the corresponding irrigation programmer, with the purpose of optimizing the use of irrigation water and thereby reducing irrigation water consumption, is characterized in that the mechanism is constituted from a cylindrical housing ( 2 ) that is arranged on the inside of the corresponding emitter ( 1 ), for the passage of water through the emitter, the cylindrical housing ( 2 ) which sets a watertight compartment through which water will pass in an upward direction and inside of the housing is mounted a first disc-shaped part ( 3 ) that can be axially displaced via water pressure in upward direction against a spring ( 4 ), the first disc-shaped part ( 3 ) having a concentric hole ( 5 ) which includes helical knurls ( 6 ) for positioning a cylindrical body ( 7 ) having corresponding helical knurls such that the axial displacement of said disc-shaped part ( 3 ) produces a rotational movement of the tubular body ( 7 ) that causes a corresponding rotation of a cylindrical part ( 9 ) with an axial stem ( 8 ) snap coupled on the cylindrical body ( 7 ), such cylindrical part ( 9 ) relating to a second disc-shaped part ( 12 ) located above and having four holes ( 14 ) equally spaced from each other for mounting respective end screws ( 15 ), the greater or lesser tightening of which screws sets the operation for one or another period of time of the irrigation emitter with respect to the total time, commanded by the irrigation programmer.
