Patent ID: 7913935

Claim:
An in-line system of mini sprinklers, comprising— a tubular conduit having inner and outer surface areas, fitted for a liquid flow under pressure through it and formed with at least one opening along its length; and at least one mini sprinkler unit that is at least substantially embedded within said tubular conduit, coupled to flow of said liquid within it and mounted to it around said opening, and comprises— a mobile liquid distributing assembly movable through said opening, such that when liquid's pressure in said tubular conduit increases, said liquid distributor moves and protrudes beyond said outer surface area of said tubular conduit in order to sprinkle said liquid outwards of said tubular conduit; and a body assembly formed with— a surface area sector adapted for being mounted upon said inner surface area of said tubular conduit around said opening; and an inner volume with said surface area formed around it; and a liquid inlet coupled to said inner volume; and a liquid distributing assembly installed within said inner volume of said body assembly, being, upon liquid pressure rising in said tubular conduit, mobile relative to said body assembly, in a manner coupling it to flow of liquid into it arriving from said liquid's inlet of said body assembly; and biasing means for forcing of said liquid distributing assembly, towards said body assembly; so that when liquid pressure in said tubular conduit increases, propelling of said liquid distributor to move towards and protrudes beyond said outer surfaces area of said tubular conduit and relative to said body assembly, required to overcome said biasing means force; and concurrent with liquid pressure decreasing within said tubular conduit, said biasing means for forcing of said liquid distributor assembly towards said body assembly, propel said liquid distributor assembly to return and move inwards into said tubular conduit and relative to said body assembly; wherein the biasing means for forcing of said liquid distributing assembly towards said body assembly, comprises an elastomer ring.
