A water distribution device adapted to be connected to a pressurized water supply line includes a valve controlling the flow of water from the supply line to a water distributor, a cyclically-operable-timer driven through cycles of operation by the energy of the pressurized water, and a coupling between the timer and the valve, which coupling is effective to actuate the valve to its open position for a minor portion of each cycle, and to actuate the valve to its closed position for a major portion of each cycle. Preferably, the cycles are from 1-60 minutes each, and the minor portion of each cycle is about one-fifth to one-fiftieth of the complete cycle. Also described is a water distribution system including a plurality of such devices connected to a common water supply line and randomly operated.

A water distribution device adapted to be connected to a pressurized water supply line, characterized in that it includes: a valve controlling the flow of water from said water supply line to a water distributor; a cyclically-operable-timer; means for driving said timer through cycles of operation by the energy of the pressurized water in said supply line; said cyclically-operable-timer comprising a displaceable member; means for reciprocating said displaceable member in a continuous manner by the energy of the pressurized water in the supply line through a forward stroke and a return stroke during each cycle; a retarding device acting on the displaceable member to slow down its movement during at least one of said strokes; a valve actuator; and a coupling between said displaceable member and said valve actuator effective, during predetermined points in said forward and return strokes of the displaceable member, to cause the valve actuator to actuate the valve to its open position for a minor portion of each cycle, and to actuate the valve to its closed position for a major portion of each cycle.
