摘要： 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.

摘要： 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.

摘要： A dual piston accumulator, in particular for a hydrostatic hybrid drive system for vehicles, replaces a high pressure hydro accumulator and a low pressure hydro accumulator. Inside a single accumulator housing (2) extending 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 chambers border an intermediate piece (12) separating the high pressure side (4) from the low pressure side (6). A common piston rod (14) extends through the intermediate piece for both accumulator pistons (8, 10). The wall width of the housing (2) corresponding to the high pressure part (4) is greater than the opposite reduced wall width corresponding to the low pressure part (6).

摘要： Examples described herein relate to compact and replaceable accumulator to be utilized in a chassis-level cooling device. The accumulator is a low pressurized device having a housing, a bladder, and a compressible fluid. The housing has an inner surface defining a volume and an opening. The bladder is disposed within a volume portion and attached to the opening. The bladder includes a plurality of elongated wall sections foldably coupled to each other and defining a bladder volume therebetween. The bladder inflates by unfolding the plurality of elongated wall sections to increase the bladder volume in response to an increase in a pressure of a working fluid inside the bladder volume. The compressible fluid is contained in a remaining volume portion between the inner surface of the housing and the bladder. The compressible fluid is compressed to an offset pressure in response to inflation of the plurality of elongated wall sections.
