Abstract
A method and apparatus for producing compressed air includes sealing air in a container capable of reducing its volume by external hydraulic pressure. A weight having a larger specific gravity than water is attached to the container to sink the container deep under water. Compressed air is produced when the volume of the container is reduced by hydraulic pressure, and is transferred into a recovery vessel connected to the container via a check valve. The weight is then separated from the container to cause the container to float on the water by the action of buoyancy. The compressed air can then be recovered from the recovery vessel.
Claims17
An apparatus for compressing air, comprising:
- a container, said container defining an air chamber therein that is capable of having its volume reduced by external hydraulic pressure;
- a recovery vessel connected to said container by a check valve for recovering compressed air produced when the volume of said chamber is reduced by hydraulic pressure;
- and
- means for sinking said container and said recovery vessel under water, said means comprising a weight attached to said container.
An apparatus for compressing air, comprising:
- a container, said container defining an air chamber therein that is capable of having its volume reduced by external hydraulic pressure;
- a recovery vessel connected to said container by a check valve for recovering compressed air produced when the volume of said chamber is reduced by hydraulic pressure;
- a weight connected to said container and said recovery vessel;
- and
- a release mechanism for automatically releasing said weight after said air chamber has been reduced in volume a predetermined amount.
A method of compressing air, comprising:
- sealing air in a container that is capable of having its volume reduced by external hydraulic pressure;
- attaching a weight having a larger specific gravity than water to the container to sink the container under water;
- transferring, under pressure, compressed air produced by hydraulic pressure reducing the volume of the container through a check valve and into a recovery vessel connected to the container;
- separating the weight from the container to cause buoyancy to cause the container to rise and float on the water;
- and
- recovering the compressed air from the recovery vessel.
