ABSTRACT:
A playground unit having a rotatable horizontally disposed deck adapted to support at least one passenger is provided with a control device operatively connected to the deck to limit the rotational speed thereof. The control device is a hydraulic governor comprising a fluid reservoir, a pump, and a valve with interconnecting fluid lines and check valves providing appropriate directional flow of fluid between the reservoir, pump and valve. The valve automatically moves between an open and closed position depending upon the rotational speed of the unit. The force required to maintain the rotational speed of the playground unit is much greater when the valve is closed as compared to when the valve is open.
