Beschreibung
Zusammenfassung:	The invention relates to a buoyancy device with a constant and adjustable volume intended for any submersible entity capable of submersion at various depth, and comprising at least one float with a flexible member and filled with gas, the pressure of which is adjusted according to the submersion depth, and such that: the membrane is elastic and defines a gas volume that varies according to the elasticity of said membrane and to the relative inner pressure of said volume relative to the outer environment pressure. An expander-discharge system is used for supplying and emptying the gas to or from the inner volume of the float.
