    Abstract: An accumulator includes a pressure container, a tubular bellows, a bellows cap divisionally defining a liquid chamber and a gas chamber in cooperation with the bellows. A stay provided with a through hole partitions the liquid chamber into a closed liquid chamber on a side of the bellows and an open liquid chamber on a side of the liquid pressure port. The bellows cap includes an elastic abutment part provided with an annular sealing part positioned around the through hole to face the through hole, a buffering part is positioned on a radially inner side of the sealing part, and communication passages always communicating with the through hole are formed in the buffering part of the elastic abutment part.

    Abstract: The invention relates to a system for improving the energy efficiency in hydraulic systems, comprising at least one working cylinder (58) which, in an operating state, operates as a consumer of hydraulic energy and, in a different operating state, as a generator of hydraulic energy, and a hydraulic accumulator (1) which, in an operating state of the working cylinder (58), can be charged by the same for storing energy and, in a different operating state, can be discharged for delivering energy to the working cylinder (58). The invention is characterized in that at least one hydraulic accumulator is provided in the form of an adjustable hydropneumatic piston accumulator (1), in which are formed a plurality of pressure chambers (19, 21, 23, 25) which adjoin effective surfaces (11, 13, 15, 17) of different sizes on the fluid side of the accumulator piston (5), and an adjusting arrangement (51) is provided which connects a selected pressure chamber (19, 21, 23, 25) or a plurality of selected pressure chambers (19, 21, 23, 25) of the piston accumulator (1) to the working cylinder (58) as a function of the pressure level that prevails respectively on the gas side of the piston accumulator (1) and on the working cylinder (58).

    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.
