ABSTRACT:
A lawn sprinkling installation has a series of dosing valves arranged in cascade to each successively deliver a set quantity of water to a sprinkler. Each dosing valve has a hinged clapper biased to normally open a first outlet leading to the sprinkler and close a second outlet connected to the inlet of the successive dosing valve. Volumetric dosing means hold each clapper to close the first outlet and open the second after delivery of a regulated quantity of water and hold the clapper as long as the water pressure is maintained. When the last dosing valve shuts off supply to the last sprinkler, a gate valve supplying the first dosing valve is automatically or manually closed to allow water in the pipes joining the dosing valves to drain through a discharge orifice, thus enabling automatic resetting of the clappers.
