ABSTRACT:
An in-line system of mini sprinklers comprising a tubular conduit having inner and outer surface areas, and fitted for the flow of pressurized liquids. This tubular conduit has one or more openings along its length, and at least one mini sprinkler unit embedded within the tubular conduit at each opening. Each mini sprinkler unit comprises a liquid distributing assembly and biasing means. As pressure within the tubular conduit increases, inward force exerted by the biasing means is overcome, and the liquid distributing assembly moves outward. As the liquid distributing assembly protrudes beyond the outer surface of the tubular conduit, liquid escapes and sprinkles onto the ground. As pressure is decreased within the tubular conduit, the biasing means force the liquid distributing assembly back to its original position.
