Abstract
A self-contained open-circuit breathing apparatus for use within a body of water naturally containing dissolved air. The apparatus is adapted to provide breathable air to a diver. The apparatus comprises an inlet means for extracting a quantity of water from the body of water. It further comprises a separator for separating the dissolved air from the quantity of water, thereby obtaining the breathable air. The apparatus further comprises a first outlet means for expelling the separated water back into the body of water, and a second outlet means for removing the breathable air and supplying it for breathing. The air is supplied so as to enable all of it to be expelled back into the body of water after it has been breathed.
Claims52
A self-contained open-circuit breathing apparatus for use within a body of water naturally containing dissolved air, adapted to provide breathable air to a diver, the apparatus comprising an inlet-means for extracting a quantity of water from said body of water, a separator for separating-said dissolved air from said quantity of water, thereby obtaining said breathable air, a first outlet means for expelling the separated water back into said body of water, and a second outlet means for removing said breathable air and supplying it for breathing so as to enable all of the air, after it has been breathed, to be expelled back into the body of water.
A self-contained open-circuit breathing apparatus for use within a body of water naturally containing dissolved air, adapted to provide breathable air to a diver, the apparatus comprising
- an inlet means for extracting a quantity of water from said body of water,
- a separator for separating said dissolved air from said quantity of water, thereby obtaining said breathable air,
- a first outlet means for expelling the separated water back into said body of water, and
- a second outlet means for removing said breathable air and supplying it for breathing so as to enable all of the air, after it has been breathed, to be expelled back into the body of water,
- further including an air bag to which the breathable air is transferred for storage,
- wherein the separator is adapted to shut down when the air bag fills to a predetermined extent and reactivates when the air bag empties to a predetermined extent.
A method for providing breathable air to a diver from a body of water naturally containing dissolved air comprising the steps of:
- drawing a quantity of water from said body of water;
- separating said dissolved air from the drawn quantity of water;
- expelling the separated quantity of water and supplying the separated air for breathing;
- expelling all of the air back into said body of water after it has been breathed.
A method for providing breathable air to a diver from a body of water naturally containing dissolved air comprising the steps of:
- drawing a quantity of water from said body of water;
- separating said dissolved air from the drawn quantity of water;
- expelling the separated quantity of water and supplying the separated air for breathing;
- expelling all of the air back into said body of water after it has been breathed,
- wherein said expelling of the separated water serves to propel the diver.
A self-contained breathing apparatus for use within a body of water naturally containing dissolved air, adapted to provide breathable air, the apparatus comprising an inlet means for extracting a quantity of water from said body of water, a separator for separating said dissolved air from said quantity of water by passing said quantity across a pressure drop, thereby obtaining said breathable air, a first outlet means for expelling the separated water back into said body of water, and a second outlet means for removing said breathable air and supplying it for breathing so as to enable the air, after it has been breathed, to be expelled back into the body of water.
