1. 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 its consumption, is characterized in that it is constituted from a cylindrical housing (2) that is arranged on the inside of the corresponding emitter (1), for the passage of water through it, the cylindrical housing (2) of which sets a watertight compartment through which water will pass in upward direction and inside of which is mounted a first disc-shaped that can be axially displaced in upward direction by the pressure of the water against a spring (4), being such first disc-shaped part (3) affected by a concentric hole (5) for positioning a cylindrical body (7) affected by external helical knurls (6) complementary to others planned in that concentric hole (5) of the first disc-shaped part (3) such that the axial displacement of said disc-shaped part (3) produces a movement of rotation of the tubular body (7), dragging with it 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 affected by four holes (14) equally spaced from each other for mounting respective end screws (15), the greater or lesser tightening of which 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.
2. Self-regulating mechanism for irrigation emitters, according to claim 1, characterized in that the cylindrical part (9) is equipped with an external lateral fin (10) as stop for limiting the rotation of the same.
3. Self-regulating mechanism for irrigation emitters, according to claim 1, characterized in that the second disc-shaped part (12) is complemented by a pair of lateral parts (13) in non-return valves functions for the cylindrical part (9).
4. Self-regulating mechanism for irrigation emitters, according to claim 1, characterized in that the rotational movement of the cylindrical part (9) produced by the upward displacement of the first disc-shaped part (3) is of 90\xb0 and to the left.
5. Self-regulating mechanism for irrigation emitters, according to claim 2, characterized in that the inner end of each of the screws (15) is susceptible to establish, in accordance with their degree of tightening, a stop for the lateral fin (10) of the cylindrical part (9) and determining one or another opening period of the emitter during the entire irrigation time commanded by the irrigation programmer.
6. Self-regulating mechanism for irrigation emitters, according to claim 2, characterized in that the rotational movement of the cylindrical part (9) produced by the upward displacement of the first disc-shaped part (3) is of 90\xb0 and to the left.
7. Self-regulating mechanism for irrigation emitters, according to claim 3, characterized in that the rotational movement of the cylindrical part (9) produced by the upward displacement of the first disc-shaped part (3) is of 90\xb0 and to the left.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
1. An auto-balancing device mounted on a spindle of a motor of a disk player, said auto-balancing device comprising:
a device shell, said device shell comprising an outer race, a hub, a center axle hole axially extended through the center of said hub and mounted on the spindle of said motor, an open chamber defined around the periphery of said hub within said outer race, an inner race suspended in said open chamber and concentrically arranged between said outer race and said hub, an inner annular track defined around the periphery of said hub within said inner race, and an outer annular track defined around the periphery of said inner race within said outer race,
a plurality of rolling balls moving in said inner annular track; and
a balancing fluid filled in said outer annular track.
2. The auto-balancing device as claimed in claim 1, further comprising an oil seal fastened to said device shell to seal said balancing fluid in said outer annular track.
3. The auto-balancing device as claimed in claim 1, wherein said balancing fluid is a fluid having a high viscosity.
4. The auto-balancing device as claimed in claim 3, wherein said balancing fluid having a high viscosity is oil.
