Said piston separates a fluid side (15) of the accumulator from the gas side (23) thereof and comprises two sealing areas (17, 25) which are offset in relation to each other in the axial direction thereof, said sealing areas being arranged on the circumference thereof and being displaced on the inner wall of the accumulator housing. The invention is characterised in that the accumulator housing (1) is provided with a ventilation device (31) between said sealing areas (17, 25) for discharging leaking means passing through the sealing areas (17, 25).
