Automatic irrigation regulator controlled by water evaporation
First Claim
1. A magnetic water valve actuated by a floating magnet comprising:
- a water containing water;
a floating magnet floating in said water and moving up and down as a level of said water fluctuates comprising a float means having a ring magnet attached thereto,a two piece armature attached to said ring magnet at opposite ends thereof to substantially confine a magnetic field generated by said magnet to a space between the two pieces of said armature of said ring magnet on and around an axis thereof;
a magnetic water valve located in said container, said valve being opened when said magnet and armature approaches said valve to allow water to flow therethrough and being closed when said magnet and armature move away from said valve so that said valve is not under the influence of said magnetic field, said valve being closed by a rubber pad closing an outlet of said valve under the force of a spring.

Abstract
The irrigation regulator, 1 and 2, releases water at appropriate intervals of time, which are controlled by the water evaporation rates in an evaporation pan (19). A water level sensor and valve system (7), (14), (9), (15) and (13), release irrigation water from the time the water level in the evaporation pan drops at a certain low level (2), due to evaporation, until is restored to the original high level (1), with the supply of water to the evaporation pan, during irrigation.
In cases when from a water source a number of sectors of an irrigation network have to be supplied with water available at rates which can satisfy one sector at a time, regulators of a number equal to the number of sectors, with double outlet water valves (8), may be interconnected as shown in the FIGS. 3, 4, and 5, so that when the one regulator delivers water for irrigation, the others do not.
