| 摘要 |
The invention relates to a dual piston accumulator which is provided, in particular, in a hydrostatic hybrid-drive system for vehicles to replace a high pressure hydro accumulator and a low pressure hydro accumulator, wherein, inside a single accumulator housing (2) which extends in the axial direction in a single piece over a high pressure part (4) and a low pressure part (6), an accumulator piston (8, 10) defines a high pressure-sided fluid chamber (16) and a low pressure-sided fluid chamber (18), both of which border an intermediate piece (12) separating the high pressure side (4) from the low pressure side (6) through which the common piston nod (14) extends for both accumulator pistons (8, 10). Said accumulator is characterised in that the wall width of the housing (2) corresponding to the high pressure pan (4) is greater than the opposite induced wall width which corresponds to the low pressure pan (6).
