Abstract: A system filled with a fluid, designed for underwater applications, in which the interior of a housing and/or tank forms a fluid region which is sealed with respect to the surrounding seawater region, includes at least one hydraulic pressure compensation device, which at least raises the pressure level of the fluid region to the ambient pressure prevailing in the seawater region. The pressure compensation device is constructed in two stages in such a way that at least one store having a flexible wall region and at least one piston store having a displaceable piston are arranged in series. The use of the pressure compensation device to pressurize at least one housing filled with fluid for a hydraulic actuating shaft is also proposed.

Abstract: A piston-in-sleeve accumulator includes a cleaning element positioned on the piston and configured to remove and prevent debris from lodging between the piston and a cylindrical nonpermeable sleeve within which the piston slides. A seal on the piston is positioned to engage an opposing surface in the event of a leak, and thereby prevent the possibility of a complete drainage of pressurized fluid from occurring through the accumulator's fluid port. A position contactor switch is further provided to signal position of the piston within the accumulator.

Abstract: A breathable low pressure accumulator includes a housing with a cylindrical bore formed therein. A piston slides within the bore and includes an elastic piston head. A biasing member urges the piston towards a first end of the bore. At least one passage communicates between an exterior of the housing and a volume that is enclosed by the bore and the elastic piston head. The elastic piston head is formed of rubber. The elastic piston head is molded into the piston.

Abstract: A piston-type accumulator includes a separating piston (24) axially displaced inside an accumulator housing (10) and separating two spaces from one another inside the accumulator housing (10), particularly a gas side (22) from a liquid side (20) of the accumulator. Due to the fact that the separating piston (24) is predominantly or completely made of a plastic material, it can be provided with a very light weight reducing the overall installation weight of the piston-type accumulator.

Abstract: A hydraulic accumulator includes a piston (3) capable of moving in an accumulator housing (1) in its axial direction and separating a gas side (5) from a liquid side (7) of the accumulator housing (1). Guide elements (9, 17) designed to co-operate with the accumulator housing wall (1), as well as at least one sealing element (15), are arranged at the periphery of the piston. The sealing element is arranged offset in the axial direction relative to the guide elements (9, 17), and is located between the guide elements. In the piston (3), a pressure compensating channel (19) forms, at the piston periphery, a liquid flow path between the liquid side (7) and a space (2) located between the guide element (17) nearest to the liquid side (7) and the sealing element immediately next in the axial direction. A device (25) reducing the cross-section of the passage of the pressure compensating channel (19) is located in it.
