    Abstract: The pressure accumulator (10) comprises a cylindrical housing (12) having a bore (14) with a piston received slidably therein. The piston (30) has an H-shaped cross section and includes a reduced diameter portion (34) extending longitudinally along the piston (30), and a sealing device (36, 38) disposed at each end of the reduced diameter portion (34). A cylindrical sleeve (44) is received in the reduced diameter portion (34) such that each end of the sleeve (44) abuts a respective sealing device (36, 38). The housing (12) has an exterior circumferential groove (20) with an 0-ring (26) therein, and a radial opening (22) extending between the circumferential groove (20) and bore (14). Alternatively, the piston (30) may have a longitudinal opening (61) extending from one side of the piston to grooves (63, 64) at the other end (32), the grooves (63, 64) receiving a ring (72) which is subjected to fluid pressure transmitted through the longitudinal opening (61) and expanded radially outwardly against an angled portion (73) of a force-transmitting member (74) which moves longitudinally against seals (76, 77) disposed in one of the grooves (63, 64).

    Abstract: A hydropneumatic pressure accumulator has an outer tube forming the accumulator housing. A flexible separating element is formed by a section of a hose, extends in the longitudinal direction inside of the outer tube and is anchored on the tube to form a seal. On the outside and inside of the hose, receiving spaces separated from one another are formed within the tube. A support body is surrounded by the hose and has fluid passages. At least in sections, the support body cross sectional shape is not round. The hose is closed on its one end and is anchored only on its other open end together with an adjacent end of the support body along the outer tube. The size of the outside surface of the hose is only slightly smaller than the size of the inside surface of the outer tube facing it. The size of the outside surface of the support body is slightly smaller than that of the inside surface of the hose facing it.
