Abstract
The device for buoyancy is intended to be used by scuba divers. It allows the adjustment of its buoyancy and keeps this buoyancy constant even at changing water pressure. Its weight is low. The device works with a mechanism for pressure control. The controller keeps the pressure difference between the inside and the outside of the tank constant. The walls of the tank are expandable to allow the adjustment of the displaced volume.
