A gas container (2) comprising a gas inlet (6), a gas outlet (8), a variable-volume chamber (4) connected to the gas inlet (6) and the gas outlet (8) and a constant force means (10, 12) acting on the variable-volume chamber 4 in such a way that constant gas pressure prevails in the variable-volume chamber (4), regardless of variations in the chamber's volume, is disclosed. A simple and reliable design providing constant force is achieved when the constant force means (10, 12) comprises a spring (10) and a force transfer means (12) which interact with each other through a center of rotation (14) and an application point (16), whereby the center of rotation (14) and the application point (14) are arranged at a variable distance from each other, said distance varying according to the variation in the volume of the variable-volume chamber (4). <IMAGE> |
