Apparatus constrainable to a diver for buoyancy control

Abstract

An apparatus constrainable to a diver, including a buoyancy control system for a diver including: —a rigid means which identifies an operating zone; the operating zone being intended to receive a gas and an incompressible liquid; the zone being defined by a first chamber or by the sum of at least a first and a second chamber; —a first means for introducing the incompressible fluid into the operating zone; —a first means for introducing the gas into the operating zone; —a pressurised tank of the gas, the first means for introducing the gas being operatively interposed between the tank and the operating zone; —a means for evacuating a fluid from the operating zone, the fluid being the gas and/or the incompressible liquid.

1 . An apparatus constrainable to a diver, comprising a buoyancy control system for a diver comprising:
 a rigid means which identifies an operating zone; said operating zone being intended to receive a gas and an incompressible liquid; said zone being defined by a first chamber or by the sum of at least a first and a second chamber;   a first means for introducing the incompressible fluid into said operating zone;   a first means for introducing the gas into said operating zone;   a pressurised tank of said gas, said first means for introducing the gas being operatively interposed between the tank and the operating zone;   a means for evacuating a fluid from the operating zone, said fluid being said gas and/or said incompressible liquid.   
     
     
         2 . The apparatus according to  claim 1 , wherein said rigid means comprises a casing defining said operating zone, said operating zone having a constant volume. 
     
     
         3 . The apparatus according to  claim 2 , wherein said casing extends between a first end zone and a second end zone; the first means for introducing the incompressible fluid being situated in the first end zone; and at least a part of the means for evacuating being situated in the second end zone to allow the discharge of gas from the operating space. 
     
     
         4 . The apparatus according to  claim 1 , wherein said first chamber is in communication both with the first means for introducing the incompressible fluid and the first means for introducing the gas. 
     
     
         5 . The apparatus according to  claim 1 , wherein said first chamber is in communication with the first means for introducing the incompressible fluid and said second chamber is in communication with the first means for introducing the gas. 
     
     
         6 . The apparatus according to  claim 1 , wherein said first and said second chamber are at least in part defined by a deformable bellows which separates the first and the second chamber. 
     
     
         7 . The apparatus according to  claim 1 , wherein the evacuating means comprises:
 a first means for discharging the incompressible fluid from said operating zone;   a first means for discharging the gas from said operating zone.   
     
     
         8 . The apparatus according to  claim 7 , wherein said first means for discharging the gas comprises a variable-resistance air discharge outlet. 
     
     
         9 . The apparatus according to  claim 1 , wherein it comprises a second means for introducing the gas into said operating zone, said second introducing means being activated as a function of the external ambient pressure. 
     
     
         10 . An operating method of an apparatus according to  claim 1 , comprising the steps of:
 increasing the thrust downwards during a dive by introducing water via said first means for introducing the incompressible fluid and discharging gas from the operating zone via the evacuating means;   increasing the thrust upwards during an underwater dive by introducing gas originating from said tank into the operating zone, via the first introducing means, while simultaneously discharging water from the operating zone via the evacuating means.
