Buoyancy device for providing rotational torque - Water Wheel

[Category : - Motors]
[Viewed 233 times]

A hollow shaft (10) supporting a plurality of buoyancy legs (18) equally spaced about the periphery of the hollow shaft (10). One end of each buoyancy leg (18) is connected to the shaft (10) in a water tight manner while the opposite end of each buoyancy leg (18) supports a buoyancy chamber (22). A piston (38) is located within the buoyancy chamber (22) and is movable from a fully retracted state to a fully extended state by operation of a weight (44). The buoyancy chamber (22), when in a fully retracted state, being substantially full of water and providing a balanced state for the shaft (10). The piston (10), when in a fully extended state, providing a buoyant state of the buoyancy chamber (22) which impart rotational torque on the shaft (10). A mechanism is provided for automatically changing the position of the piston (38), from the fully retracted state to the fully extended state, or, from the fully extended state to the fully retracted state each time the buoyancy leg (18) is located in a substantially vertical orientation.
