Pressure accumulator (1) with a container body (10) for absorbing pressure forces which are formed by pressure filling of a fluid that can be filled in the storage space (11) of the container body (10), characterized in that the container body (10) is enclosed by an enveloping body (12) is, wherein between the container body (10) and the enveloping body (12) an intermediate space (13) is formed in which the fluid is received under a pressure which is less than the fluid pressure in the storage space (11) and which is greater than a Atmospheric pressure, the intermediate space (13) being filled with a deformation energy absorbing filler, preferably with a metal foam. |
