Abstract
The present invention relates to an aerial fire-fighting bucket. The bucket includes a base plate and a valve arrangement including at least one valve and a liner actuator. The base plate includes at least one aperture and the valve is arranged to block the aperture in a closed position and to allow fluid to pass from within the bucket through the aperture when in an open position. The valve is arranged to be moved by the linear actuator generally transversely across an upper face of the base plate between the closed position and the open position of the valve to progressively reveal the aperture.
