1. A pressure accumulator consisting of at least one accumulator housing (203, 303, 403) having at least one connection (211, 311, 411;

  • 213, 313, 413) for a pressure medium (221, 321, 421), in particular in the form of fluid, which can be stored in the accumulator housing (203, 303, 403), wherein a filling material (219, 319, 419) can be introduced at least partially into the accumulator housing (203, 303, 403), said filling material having cavities or forming at least one cavity for at least partial accommodation of a pressure medium (221, 321, 421) and/or at least one additional pressure medium (249, 349, 449), characterized in that at least one elastomeric separation element (215, 315, 415), preferably in the form of a separation diaphragm (215, 315) or a separation bladder (415), subdivides the accumulator housing (203, 303, 403) into at least two working spaces (245, 345, 445, 247, 347, 447), forming a hydraulic accumulator, one of these working spaces (245, 345, 445) accommodating one pressure medium (221, 321, 421), in particular in the form of a liquid, and the other working space (247, 247, 447) accommodating the other pressure medium (249, 349, 449) in the form of a working gas such as nitrogen gas, and the filing material (219, 319, 419) is at least partially limited or enclosed by the separation element (215, 315, 415).
