Abstract:
An accumulator membrane unit (2) for inclusion into an accumulator chamber (6) in an accumulator (1) for storing hydraulic energy under pressure. The accumulator membrane unit includes membrane elements (3) that are sealingly joined at their peripheries and limit an inside membrane volume (V) which varies in dependence of a pressure at an outside of the accumulator membrane unit. The invention also concerns an accumulator, a method and a rock drilling machine.
