Abstract: A piston accumulator comprising a piston (2) reciprocating within the bore of a cylinder (4) to divide the bore into a hydraulic chamber (5) and a gas chamber (6). The piston (2) includes a piston-poppet assembly (1) to equalise substan- tiallythe liquid-gas pressure appearing across the piston seal (13). The assembly (1) projects into the hydraulic chamber (5) from its housed position within a socket recess (15) formed in the piston (2). In response to an excess pressure differential between the gas chamber (6) and liquid chamber (5) of the accumulator, the assembly (1) prematurely seals off the hydraulic passage (9) which communicates with the hydraulic chamber (5) of the accumulator. This premature sealing operation traps and pressurises a small portion of hydraulic liquid within the reduced hydraulic chamber (5) so that the pressure differential which would otherwise appear across the piston seal (13) is reduced or eliminated.

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 depth compensated subsea accumulator with a cylinder with a cylinder end, a first larger bore, a cylinder shoulder and a second smaller bore, a piston sealingly and slidably engaging the first large bore with a single direction seal and having a rod attached to a first side, the rod sealingly and slidably engaging the second smaller bore, the piston having a working fluid on the first side and a compressed gas on the second side, the working fluid on the first side of the piston having a higher pressure than the gas on the second side of the piston while the piston is moving between the cylinder end and the cylinder shoulder, when the piston sealingly engages the cylinder shoulder, a portion of the working fluid on the first side of the piston within a seal diameter having a lower pressure than the gas on the second side of the piston and a portion of the working fluid on the first side of the piston outside the seal diameter having a higher pressure than the gas on the second side of the piston, such that the single direction seal always encounters pressure from the same direction.

Abstract: Disclosed is a low pressure accumulator for an anti-lock brake system of a vehicle. The low pressure accumulator includes a cylinder having one end communicated with a fluid path connected to a valve and a pump and an opposite end formed with an opening, a piston moving back and forth in the cylinder, a spring installed in the cylinder to elastically support the piston, and a plug installed in the opening of the cylinder to support one end of the spring. The plug includes a vent to ventilate air through an inside and an outside of the cylinder.

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 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.
