Abstract
The tank comprises a variable volume chamber containing a liquid and defined by a wall; and a piston suitable for moving in the tank under thrust from powder gas at a temperature much higher than that of the liquid in order to decrease the volume of the chamber. The tank also comprises a deformable elastomer membrane pressed against a face of the piston outside the chamber, the membrane being suitable for thermally protecting the wall and for providing sealing between the piston and the wall.
