Abstract: This invention, through an arrangement of basic elements, has resulted in a new device for landscape irrigation which has not been previously available. This implementation is an electromechanical device which can potentially revolutionalize the entire landscape irrigation industry. During operation it cyclically varies the amount of water ejected from a sprinkler device and thereby provides a more uniform coverage than is ordinarily available. This obviates the necessity to have additional sprinklers fill in the under-watered areas. The device accomplishes this by utilizing a synchronous alternating current motor to drive a rotor which, as it rotates, varies the flow rate of the water to the sprinklers. The motor is powered by the same source that powers the valves feeding water to the sprinklers. Its use will drastically reduce the amount of irrigation water required, helping to save a precious resource.
