  • Emitters for drip irrigation systems, micro-sprinklers and similars, of the pressure compensating type and also those types whose flow varies in relation to the changes in pressure
    Patent number: 4331293
    Abstract: An emitter for use in irrigation systems of either the pressure compensating or variable flow type which emitter has an improved means of filtering and removing impurities so as to minimize the possibility of clogging. The emitter includes a first filter located inside of the fluid line or hose so as to eliminate most of the particles from ever entering the emitter. The emitter also includes structure so that once the fluid enters the emitter it is subjected to a cyclone path while going through multiple decompression chambers. This cyclone type turbulent path deposits the impurities against the outside walls of the decompression chambers where they accumulate in a collecting chamber for easy removal.
