Title
(EN) METHOD OF AND APPARATUS FOR BOUYANCY COMPENSATION FOR DIVERS
(FR) PROCÉDÉ ET APPAREIL DE COMPENSATION DE FLOTTAISON POUR DES PLONGEURS
Abstract
(EN)
An improved buoyancy compensation device having a lesser change in buoyancy with depth than conventional buoyancy compensation devices which use ambient pressure bladders is disclosed. The improved device comprises one or more elastic members that, throughout the working range of diving pressures and volumes, is always elastic and, when pressurized, maintains an internal air pressure that is always greater than the ambient pressure at any dive depth. The invention also relates to a method of providing a buoyancy compensation device with an elastic member having a lift versus depth characteristic that approaches the lift versus depth characteristic of a constant or fixed volume buoyancy compensation device.
(FR)
L'invention porte sur un dispositif de compensation de flottaison amélioré ayant un changement de flottaison en fonction de la profondeur moindre qu'avec des dispositifs de compensation de flottaison classiques, lequel dispositif utilise des vessies à pression ambiante. Le dispositif amélioré comprend un ou plusieurs éléments élastiques qui, à travers la plage de travail de pressions et de volumes de plongée, est toujours élastique et, lorsqu'il est mis sous pression, maintient une pression d'air interne qui est toujours supérieure à la pression ambiante à n'importe quelle profondeur de plongée. L'invention porte également sur un procédé de délivrance d'un dispositif de compensation de flottaison avec un élément élastique ayant une caractéristique d'ascension en fonction de la profondeur qui s'approche de la caractéristique d'ascension en fonction de la profondeur d'un dispositif de compensation de flottaison à volume fixe ou constant.
