Abstract

A multifunction pressure accumulator (21) comprised of a pressure-proof reservoir having at least two pressure connections (4, 10) and at least two leak-proof partition walls (2, 5) moving or flexing due to pressures conveyed to the reservoir and a pressure chamber formed by means of said partition walls and filled with gas. For filling of pressure chamber (13) the gas filling channel (14) is taken to the pressure chamber side at least through one partition wall.
