Abstract:
1. A liquid flow rate modulator used in an irrigation system, the modulator comprising: a magnetic drive body comprising an upper compartment and a lower compartment, the lower compartment being completely sealed from the upper compartment; said upper compartment housing a drive motor electrically connected to a sprinkler controller or control valve located outside of the magnetic drive body, said drive motor including an output shaft; said upper compartment further includes an upper magnet carrier having an upper surface connected to the motor output shaft and a lower surface to which is connected a first plurality of magnets; said lower compartment housing a lower magnet carrier having an upper surface connected to a second plurality of magnets and a lower surface to which is connected a sculptured modulating rotor, said rotor being supported by corrosion resistant bearings to allow free motion under static and dynamic water pressure loading, wherein said sculptured modulating rotor rotates continuously throughout a watering cycle in response to the drive motor and magnets to alter, on a regular basis, the amount of water that flows through the irrigation system, and thus, vary the throw distance of water from any particular sprinkler.
