ABSTRACT:
The illustrative embodiments of the invention described comprise systems for pulse distribution of irrigating fluid. The systems described include a header that feeds at least one irrigating line in which an array of emitter valves are connected in series to a header. Elastic tubes between each of the emitter valves serve as reservoirs for the irrigating fluid between pulses. A pulser connects the irrrigating fluid conduit to the header in response to activation from a pilot valve. An optional accumulator bellows that is joined to the header collects surplus irrigating fluid and returns it to the system at the appropriate time in the pulse cycle. The pilot valve, moreover, responds to pressure fluctuations by activating and deactvating the pulser. An adjustable spring biased variable capacitance chamber and a fluid diode, moreover, that are coupled to the pilot valve combine to determine the irrigation pulse repetition rate.
