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 fluid pressurization element in fluid communication with the fluid portion of the vessel and having an inlet configured to accept fluid, the fluid pressurization element configured to communicate fluid from the inlet into the fluid portion;
- wherein the fluid pressurization element comprises a manually actuated hydraulic pump.
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 fluid pressurization element in fluid communication with the fluid portion of the vessel and having an inlet configured to accept fluid, the fluid pressurization element configured to communicate fluid from the inlet into the fluid portion;
- further comprising an electrical energy storage device, and wherein the fluid pressurization element comprises an electric pump configured to accept energy from the electrical energy storage device.
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, the fluid pressurization element configured to pump fluid from the inlet into the fluid portion;
- further comprising 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.
