Abstract
A self-contained battery-operated three-way control valve is repetitively cycled by a clock timer for cyclical control of an automatic hydraulic valve. The control valve is driven to one or the other of two limit positions by a reversible motor under control of forward and reverse motor circuits that are sequentially energized by a timer and de-energized by limit switches. A reverse control, also operated by the timer, selects one or the other of the motor circuits.
