    Abstract: A hydraulic system (1) is provided comprising a supply port arrangement (P, T), a working port arrangement (A, B), and a booster section (7), said supply port arrangement having at least a supply port (P), said booster section (7) being arranged between said supply port arrangement (P, T) and said working port arrangement (A, B). The operational possibilities of such a hydraulic system should be extended. To this end said working port arrangement comprises at least two working ports (A, B), flow direction changing means (9) are provided changing a flow direction through said working port arrangement and inactivating means (16) are provided inactivating or activating said booster section (7) for each flow direction.

    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).
