ABSTRACT:
An automatic plant water arrangement having one water intake and several water outflows which are preceded by valves. The valves are actuated by a time-controlled mechanism, and are individually adjustable for different opening cycles. The time-controlled mechanism has a synchronous motor with a gear reduction unit, a single-tooth wheel and a mating gear with attached valve actuating disk. The valve actuation disk is provided with teeth, part of which are fixed and part of which are movable for opening the valve. A segment-shaped cam disk is located underneath the valve actuating disk, and is controlled by gears so that it pivots one of the movable teeth every sixth day into the valve engagement region. The teeth, after leaving the region are returned by springs to their initial positions.
