Abstract:
1. A diving-tank-pocket buoyancy compensator comprising: a diving-tank pocket that is articulated for containing at least a diving tank and an inflatable buoyancy air cell; the buoyancy air cell being in fluid communication with a cell end of a buoyancy compensator (BC) tube which has a tank end in fluid communication with an inside periphery of the diving tank through a regulator valve on the diving tank and through a regulator tube in fluid communication intermediate the regulator valve on the diving tank and the cell end on the BC tube; a pressure valve intermediate the tank end and the cell end of the BC tube for maintaining a constant pressure and resulting constant volume of air in the buoyancy air cell without overfill of the buoyancy air cell and thereby for providing a desired constant buoyancy with volume of air in the buoyancy air cell by adjusting for any change in volume and pressure in the buoyancy air cell resulting from intentional inlet of air through an inflation valve in the BC tube and outlet of air through a cell-outlet valve in the BC tube and outlet of air through a cell-relief valve in the buoyancy air cell selectively and resulting also from possible minor valve and air-cell leakage; and the diving tank being attachable to a predetermined diving-chute harness with at least one tank strap.
