    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: 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.

    Abstract: A hydraulic hammer is disclosed that includes at least one accumulator that is connectable to a hydraulic circuit disposed in the housing of the hammer. The accumulator includes an annular base coupled to a cover with a diaphragm sandwiched therebetween. The annular base includes a proximal end and a distal end. The proximal end of the annular base defines a first central opening. The proximal end of the base in the housing define an annular inlet that encircles the first central opening and that is in communication with the first central opening. The cover also includes a proximal end and a distal end. The proximal end of the cover is coupled to the distal end of the base with the outer periphery of the diaphragm sandwiched therebetween.
