Abstract: A hydraulic accumulator, in particular in the form of a piston accumulator, has an accumulator housing (10) and a separating element (20) arranged in the housing. The separating element is in the form of a piston, which separates a fluid side (22) from a gas side (24). At least the gas side (24) can be inspected, at least in part, by at least one sight glass (34, 36) that is fixed in the accumulator housing (10).

Abstract: A gas cylinder, in particular a high-pressure gas cylinder, includes a cylinder tube (1) having a piston rod (9) that is passed through a sealing arrangement (13) by which the gas pressure prevailing in the pressure chamber (23) of the cylinder tube (1) is sealed off against the ambient pressure. The sealing arrangement (13) has a compressed oil chamber (33) between a sealing element (31) adjacent to the pressure chamber (23) and another sealing element further away from the pressure chamber (23). Oil can be pressed in the oil chamber by a supply device (51) at a pressure that is equal to or higher than the respective gas pressure prevailing in the pressure chamber (23) of the cylinder tube (1).

Abstract: The invention relates to a gas cylinder, in particular a high-pressure gas cylinder, the cylinder tube (1) of which has a piston rod (9) that is passed through a sealing arrangement (13) by which the gas pressure prevailing in the pressure chamber (23) of the cylinder tube (1) is sealed off against the ambient pressure. The invention is characterised in that the scaling arrangement (13) has a compressed oil chamber (33) between at least one sealing element (31) adjacent to the pressure chamber (23) and at least one more sealing element further away from the pressure chamber (23), into which oil chamber oil can be pressed in by means of a supply device (51) at a pressure that is equal to or higher than the respective gas pressure prevailing in the pressure chamber (23) of the cylinder tube (1).

Abstract: Disclosed is a conveying device for fluids with an inlet and an outlet and a conveying part which is connected therebetween and can be actuated by a drive part, wherein the conveying part has a fluid-tight media-separating device with a variable chamber volume, which becomes connected in a fluid-conducting manner via its receiving chamber to the inlet or the outlet, and which, by means of the drive part, receives fluid via the inlet as part of an intake stroke, increasing the chamber volume, and discharges the received fluid via the outlet as part of a discharge stroke, reducing the size of said chamber volume.

Abstract: A device for relieving pressure in hydraulic lines, in particular in connecting lines that have coupling points (6, 8), are located between attachments and include hydraulically actuated actuators and working implements supplying the attachments. A control block (2) is connected to the line to be relieved and includes an openable non-return valve (12) as a relief valve. A pressure accumulator (22) holds a relieving volume when the non-return valve is open. An actuating member (38) can be moved manually to open the non-return valve (12) and is arranged to be movable on the housing (24) of the pressure accumulator (22).

Abstract: A device (1) adjusts a media pressure relative to an ambient pressure defined by a depth-dependent sea water pressure during use of the device (1). The sea water pressure acts on a compensator device (35) that permits a reversible change in length or elongation. At least two compensator elements (41) of the compensator device (35) are provided in series in the direction of the change in length or elongation.
