  • Patent number: 4178954
    Abstract: A new and improved automatic diaphragm valve having an inlet and two separate outlets for use in a fluid distribution system. The valve cycle automatically opens both outlets when fluid stops flowing into the inlet. Each time the fluid starts flowing through the inlet the valve automatically and alternately opens one valve outlet and closes the other valve outlet. The valve cycling mechanism is alternately cocked into a positive first and second cocked position in order to open the previously closed valve outlet and to close the previously opened valve outlet during the next half cycle. When this valve is connected at each branching point in a fluid distribution system, the valve will cause cyclic distribution of fluid from the terminal branches of the system in a serial manner.
