<p>A piston storage device has a piston (13) with two collars (15, 16) separated by a central necked portion (14). A sealing means is arranged in both piston collars. The sealing means facing the gas chamber (18) is designed in such a manner that pressurized gas can enter the gas chamber (18) via a bore (32) through the wall of the housing, via the sealing means which is then adjusted accordingly. When the pressure in the gas chamber is as high as the pressure of the gas supply source, the sealing means returns to its original position, this sealing the gas chamber from the fluid chamber (19).</p> |
