ABSTRACT:
A mechanism for selectively distributing liquid flow to at least two separate outlet conduits includes a tank for receiving liquid and at least two tubular members having bellows-like sections mounted in the tank in flow communication with the associated outlet conduits. Actuator devices are connected for selectively compressing or extending the bellows-like sections to determine the elevations of the mouths of the tubular members within, or above, the liquid in the tank to thereby control the flow through the outlet conduits.
