Abstract: An annular tube (or other shape) of elastomeric cellular material comprising elastomeric closed cells having gas infused therein is supported by structures protruding from the bottom surface of a suction stabilizer's head and/or by structures within the interior volume of the annular body of the suction stabilizer, preferably with spacing between the outer diameter of the annular tube of the cellular material and the inner walls of the suction stabilizer body. The gas-infused closed cell material may thus be employed in new suction stabilizer or pulsation dampener or to retrofit existing suction stabilizers or pulsation dampeners designed for a gas-filled bladder.

Abstract: Accumulators normally are teed into existing conduits and require large amounts of space or are placed in spool type bores having a spring biased piston slidably disposed therein. Most times these accumulators require a bladder that is vented to the atmosphere or a fluid chamber connected to a reservoir. In the subject invention, an accumulator 24 is provided that has a fluid filled member 36 which can be disposed in a closed chamber 32 of a housing 30 and connected to a source of pressurized fluid. The fluid filled member 36 has a fixed maximum surface to volume ratio and is capable of being compressed when subjected to a pressure higher than the pressure within. The accumulator may be integral with other components in the hydraulic system 10 and can be made with varying volumetric capacities and varying precharged pressures in order to match the requirements of the hydraulic system.

Abstract: The invention concerns a pressure tank comprising a rigid casing having opposite first and second orifices, and an elastically deformable separator extending inside the casing between the two orifices and subdividing the inside volume of the casing into variable-volume first and second compartments. The second compartment communicates with a hydraulic circuit via the second orifice. The first compartment is filled with elastically deformable solid elements, and the resulting assembly behaves like a spring. In the non-compressed state, the overall volume of the elastically deformable solid elements is substantially equal to the volume of the first compartment when the separator is at rest.

Abstract: An absorber for use in a fluid delivery system is disclosed which includes a housing defining an interior chamber, a connective fitting extending from the housing in fluid communication with the interior chamber for connecting the housing to the fluid delivery system, and at least one gas-filled bladder or cell disposed within the interior chamber of the housing to accommodate changes in fluid characteristics, such as, for example, pressure and volume, within the fluid delivery system, the gas-filled bladder or cell having a predetermined pre-charge pressure and a multi-layered flexible polymeric shell including a plurality of successive relatively thin polymeric shell layers to inhibit the formation of leak paths through the shell in the event that a single shell layer fails.

Abstract: The invention relates to a mobile hydraulic system for a hybrid vehicle, comprising a hydraulic accumulator device (22), which comprises a high-pressure accumulator chamber (34) and a low-pressure accumulator chamber (35), between which a hydraulic drive unit is connected, wherein the hydraulic drive unit is used to convey an incompressible fluid from the low-pressure accumulator chamber (35) into the high-pressure accumulator chamber (34) in an accumulator operating state, wherein the incompressible fluid can be discharged from the high-pressure accumulator chamber into the low-pressure accumulator chamber (35) in a drive operating state in order to hydraulically drive the hydraulic drive unit. In order to further reduce the space requirement for the hydraulic accumulator device in the mobile hydraulic system, the low-pressure accumulator chamber (35) and the high-pressure accumulator chamber (34) are fluidically separated by a separating device (36) and arranged in a common accommodating chamber (25) in which a variable compensating volume (50) having a compressible fluid is also arranged.
