ABSTRACT:
A self-inflatable balloon and motor-driven turbine assembly has a communication discernible on a surface of the balloon and has a pneumatically sealed enclosure for the turbine. The sealed enclosure has an outlet port and which, together with the inlet port, are positioned in relation to the turbine to permit efficient flow of air or other gas into the balloon when it is desired to inflate the balloon. The outlet port or the inlet port, depending upon the embodiment, seals an enclosure when selectively operated to a closed position to prevent leaking of the gas from the inflated balloon.
