Abstract
Conventional SCUBA diving equipment is heavy and cumbersome, mainly due to the mass and size of the breathing gas carrier, i.e. the pressure vessel. A preferred pressure vessel for SCUBA diving can be as light as possible and neutrally buoyant at all stages of the dive. To achieve such preferred characteristics, the pressure vessel volume can be adjusted in accordance with the change in its mass. The present invention provides SCUBA systems that provides for the preferred characteristics.
Claims20
A self-contained breathing apparatus incorporating an adjustable buoyancy system, configured for use with breathing gas while a user is submerged in a fluid, comprising:
- a vessel comprising an outer shell defining an interior volume;
- a dynamic partitioning element mounted within the interior volume separating the interior volume into a breathing gas portion configured to supply breathing gas to the user, and a fluid portion;
- a pump in fluid communication with the fluid portion of the vessel and having an inlet configured to accept fluid from water surrounding the user, configured to communicate fluid from the inlet into the fluid portion when the pump is active;
- a purge valve in fluid communication with the fluid portion of the vessel and with fluid surrounding the user, and configured to communicate fluid from the fluid portion to fluid surrounding the user when the purge valve is open.
A self-contained breathing apparatus incorporating an adjustable buoyancy system, configured for use with breathing gas while a user is submerged in a fluid, comprising:
- a vessel comprising an outer shell defining an interior volume;
- a dynamic partitioning element mounted within the interior volume separating the interior volume into a breathing gas portion configured to supply breathing gas to the user, and a fluid portion;
- a manually actuated hydraulic in fluid communication with the fluid portion of the vessel and having an inlet configured to accept fluid, configured to communicate fluid from the inlet into the fluid portion;
- a purge valve in fluid communication with the fluid portion of the vessel and with fluid surrounding the user, and configured to communicate fluid from the fluid portion to fluid surrounding the user when the purge valve is open.

- a purge valve in fluid communication with the fluid portion of the vessel and with fluid surrounding the user, and configured to communicate fluid from the fluid portion to fluid surrounding the user when the purge valve is open;
- a meter configured to indicate the amount of breathing gas in the breathing gas portion of the vessel, wherein the meter comprises a fluid flow meter mounted in fluid communication with the pump and with the fluid portion of the vessel, responsive to fluid flow through the pump.
