<p>Disclosed herein is a hydraulic buoyant force engine whose essential component is a plurality of floats (1) engaged to two transmission chains (6,7) of two sprocket and chain combination units each disposed at either side of the floats. The float (1) is wrapped with a canvas (14) supported by several rib units (13). When the float (1) is expanded by air its buoyancy overcomes its own weight, floats up and drives the chains (6,7) to move up. When the float comes up to a gear (8) above it, a gear (17) will mate an annular gear rack (8) to act as an internal spur gear unit so as to retract the rib units (13) thereby squeezing the float (1) to discharge the contained air. The shrunk float sinks into the water together with the two chains. <IMAGE> <IMAGE></p> |
