Abstract
A closed loop buoyancy system wherein a device housing the system is submerged in a liquid filled container, the device dives to the bottom of the container, remains for a regulated amount of time, and then floats back to the surface of the liquid.
Claims14
A closed loop buoyancy system comprising
- two identical chambers, one of said chambers identified as a buoyancy chamber and the other identified as a pressure chamber;
- means for connecting said chambers so that said chambers abut one another, said connecting means containing a portion that extends into said pressure chamber;
- a t-shaped fitting attached to said connecting means and extending into said pressure chamber;
- a high volume, one-way check valve positioned on one end of said t-shaped fitting;
- a small capillary tube positioned on the other end of said t-shaped fitting;
- a valve positioned between said capillary tube and said t-shaped fitting;
- an electric pump or solenoid valve regulating the flow of air through said capillary tube;
- a ballast;
- and
- means for exerting pressure on said buoyancy chamber effecting a pressure increase on said pressure chamber.

A method for modulating buoyancy comprising
- application of pressure to one of two identical chambers, said chamber identified as the buoyancy chamber in a closed loop buoyancy system comprising
- two identical chambers, one of said chambers identified as a buoyancy chamber and the other identified as a pressure chamber;
- means for connecting said chambers so that said chambers abut one another, said connecting means containing a portion that extends into said pressure chamber;
- a t-shaped fitting attached to said connecting means and extending into said pressure chamber;
- a high volume, one-way check valve positioned on one end of said t-shaped fitting;
- a small capillary tube positioned on the other end of said t-shaped fitting;
- a valve positioned between said capillary tube and said t-shaped fitting;
- an electric pump or solenoid valve regulating the flow of air through said capillary tube;
- and
- a ballast
- submersion of said device into a volume of water larger than the volume of the device.
