Abstract
A programmable, electronically controlled sprinkler system has a hermetically sealed internal chamber which encloses all of the internal water flow, valves, mechanical and rotational components. A plurality of magnetic coupling arrangements allows external motors to control operation of the internal mechanical components without requiring any hydraulic seals.
Claims15
An oscillator assembly comprising:
- a sealed chamber;
- a turbine wheel rotatably mounted within said sealed chamber;
- a flow diverter mounted within said sealed chamber, said flow diverter being rotatably movable between a first position to direct water within said sealed chamber and rotate said turbine wheel in a first direction, and a second position to direct water within said sealed chamber and rotate said turbine in a second direction;
- an internal magnet received in said flow diverter;
- an external coupling body rotatably mounted in adjacent facing relation with an external surface of said sealed chamber;
- an external magnet received within said external coupling body;
- said internal and external magnets each having north and south poles which are aligned, magnetically coupled and in phase with each other;
- and
- a reversible motor driving rotation of said external coupling body wherein rotation of said external magnet causes a corresponding rotation of said internal magnet and said flow diverter.
