Abstract

Ein aufblasbarer Sack mit Druckausgleich für die Bergung von Gegenständen aus großen Wassertiefen besteht aus einem selbstdichtenden Werkstoff. Beim Aufsteigen des Sackes zur Wasseroberfläche ist durch einen materialspezifischen Aufbau der Wand (1) des Sackes sichergestellt, daß durch Öffnen von Poren (3) innerhalb der Wand (1) ein unzulässiger Innendruck nicht auftritt. Die Poren (3) öffnen sich bei Erreichen eines kritischen Druckes, wodurch das Gas aus dem Innenraum des Sackes in das Wasser (11) entweicht.

Figure 00000001
An inflatable sack with pressure compensation for the recovery of objects from great water depths is made of a self-sealing material. When the sack rises to the water surface, a material-specific structure of the wall (1) of the sack ensures that an inadmissible internal pressure does not occur when the pores (3) are opened inside the wall (1). The pores (3) open when a critical pressure is reached, as a result of which the gas escapes from the interior of the sack into the water (11).
