Abstract (en)
[origin: EP2226512A1] The accumulator has a base body (1) for accommodating a storage chamber (2) for gaseous medium and a retaining chamber (3) for liquid medium. A separating element (4) separates the storage chamber from the retaining chamber, where volume of the chambers is changeable. The storage chamber has storage lower chambers (5, 6) separated from each other for receiving gaseous medium at different pressures. Another separating element (9) separates the lower chambers from each other and is formed as a flexible membrane, where the membrane is attached to a support wall (10) connected with the base body. An independent claim is also included for a method for receiving and discharging liquid medium.
