Abstract: An actuator system for a fluid playground including a first elongated tubular member defining a first axially extending enclosure and having a first inlet connectable to a fluid source, and a second elongated tubular member positioned within the first tubular member, the second tubular member defining a second axially extending enclosure, and having a second inlet in fluid communication with the first enclosure and an outlet traversing the first tubular member. The outlet is connectable to at least one fluid playground device. A plug element is shaped to removably and sealably close the second inlet of the second tubular member. A resilient member urges the plug element towards sealing engagement with the second tubular member. A pressure exerted on a movable actuating element connected to the plug element causes its displacement away from sealing engagement with the second inlet, thereby allowing fluid flow to the fluid playground device.
