Abstract: A potential energy store has a hydraulic cylinder in which a piston for storing energy in the form of potential energy of the piston is arranged. A position of the piston relative to the earth's surface can be varied. A pump pumps hydraulic fluid via lines into the hydraulic cylinder such that the piston is raised. A generator converts hydraulic energy of hydraulic fluid, which is displaced out of the hydraulic cylinder as the piston falls, into electricity. A seal arrangement is at least partially arranged between the hydraulic cylinder and the piston. The seal arrangement has a sealing section with a flexible support structure for absorbing the acting forces. The support structure may be coated on one or both sides with a layer which is impervious to fluid and which seals against the passage of fluid or may be impregnated with a solidified material which is impervious to fluid.

Abstract: A hydraulic accumulator, especially a piston accumulator includes an accumulator housing (10) and a separating piston that can be longitudinally displaced in the accumulator housing (10) and divides two working chambers (12) inside the accumulator housing (10). The housing is sealed on each end by one cover part (16). At least one cover part is fixed, on one side (32) by a free longitudinal edge (34) of the accumulator housing (10). The edge is arranged against the cover part (16). By connecting the free longitudinal edge (34) of the accumulator housing (10) to the associated cover part (16) by a peripheral weld seam (46) for sealing at least one working chamber (12) from the environment in a gas-tight and/or fluid-tight manner, a reliable sealing is obtained by the weld seam (46).

Abstract: The invention relates to a fluid linear drive having a cylinder (1) which is entirely or partially filled with a pressure medium. A piston (2) is arranged inside said cylinder so as to be displaced and has a piston rod (10) which is arranged at one end of the piston (2) and is led out of the cylinder (1) in a scaling manner. The piston subdivides the interior space of the cylinder into a first chamber (6) and a second chamber (7), the piston rod (10) extending through the second chamber (7). A pump (17), which is particularly reversible and by means of which the pressure medium can be pumped into the first chamber (6) and pumped off from the first chamber (6), has a first intake and/or pressure connection (18) and a second intake and/or pressure connection (19). The first intake and/or pressure connection of the pump (17) is connected to the first chamber (6) and the second intake and/or pressure connection is connected to a storage chamber. The pump (17) is mounted in the piston (2) or in or on a bottom of the first chamber.
