ABSTRACT:
An accumulator-distributor for gathering a quantity of water under pressure and rapidly discharging the quantity of water in bursts whereby large agricultural areas can be watered from a low volume source of irrigation water is shown. An expandible chamber is provided having a flexible diaphragm as one wall thereof. Bias means carried by the flexible diaphragm are adapted to exert a pressure upon the valve member closing the outlet opening from the chamber an amount insufficient to retract the valve member against the differential pressure of the accumulated water acting on the valve member. A second member is adapted to contact and lift the valve member from the valve seat at the point of maximum expansion of the chamber whereby the differential pressure is removed from the valve member and the bias means is able to rapidly withdraw the valve member completely from the outlet opening from the chamber to allow the rapid and complete expulsion of the accumulated water therein in an optimal manner.
