Abstract (en)

[origin: EP2202412A1] The accumulator has a separating element separating inner working chambers within an accumulator housing (1) from each other, where the housing is formed by housing shells. The shells are connected with each other at its front sides by a fiber winding or a fiber clutch in a pressure-sealed manner, and are made of aluminum alloy. The winding is made of a material e.g. carbon-, Kevlar(RTM: para-aramid synthetic fiber), glass-, boron- or alumina fiber. The shells are provided in form of rotational bodies with respect to a longitudinal axis (3) of the housing.
