Abstract: According to a method for the combined pump water pressure-compressed air energy storage at a constant turbine water pressure, the energy to be stored is used to pump a liquid medium, especially water, into a pressure-tight, air-tight hollow space, in particular a pressure vessel (1 - 1.5) such that a rising level of medium compresses the gas contained in the pressure vessel (1 - 1.5), in particular air, piston-like until the vessel is filled with medium, and through a connecting conduit presses said gas into a compressed gas tank (2 - 2.5), the conduit being shut using a check valve (17.2) such that the energy is stored in the compressed gas.

Abstract: The invention is an accumulator system in which multiple elastomeric accumulators are attached in series or parallel in order to generate total differential pressure in excess of that generated in a non-series system. Also disclosed is a “stacked” accumulator system. The system stores energy when the accumulators deform from their original shape in response to the flow of a pressurized fluid. The stored energy is available for use when the fluid is released from the accumulators and the accumulators return to their original shape.

Abstract: The invention relates to a dual piston accumulator which is provided, in particular, in a hydrostatic hybrid-drive system for vehicles to replace a high pressure hydro accumulator and a low pressure hydro accumulator, wherein, inside a single accumulator housing (2) which extends in the axial direction in a single piece over a high pressure part (4) and a low pressure part (6), an accumulator piston (8, 10) defines a high pressure-sided fluid chamber (16) and a low pressure-sided fluid chamber (18), both of which border an intermediate piece (12) separating the high pressure side (4) from the low pressure side (6) through which the common piston rod (14) extends for both accumulator pistons (8, 10). Said accumulator is characterised in that the wall width of the housing (2) corresponding to the high pressure part (4) is greater than the opposite reduced wall width which corresponds to the low pressure part (6).

Abstract: A drop-in signal accumulator piston assembly replaces an original equipment (OE) signal accumulator piston in a vehicle transmission hydraulic circuit. The OE signal accumulator piston is positioned in a bore in a valve body that has an open end and a fluid port. The drop-in signal accumulator piston assembly includes a cylindrical sleeve having open first and second ends, one of the first and second ends defining a reduced diameter region, and a piston positioned in the sleeve. A spring is positioned in part in the piston and in part extending beyond and end of the piston. The sleeve is positioned in the valve body bore, with the piston, and the spring. A method for replacing an original equipment (OE) signal accumulator piston in a transmission hydraulic circuit is also disclosed.

Abstract: The present invention provides an accumulator (20) comprising a housing (21), an inner portion (23) within the housing, and a zone (27) defined between the housing and the inner portion for fluid communication with a driving fluid of a fluid-powered system whereby the inner portion is exposed to the driving fluid received within the zone. The inner portion comprises a resiliently deformable solid mass (31), wherein at least a portion of the mass is deformable in response to fluid pressure in the zone exceeding a prescribed level thereby to provide pressure relief. The deformable portion resiliently rebounds in response to fluid pressure in the zone returning to or falling below the prescribed level.
