  • Patent number: 8033107
    Abstract: A hydrostatic drive with first and second hydraulic pumps and a dual-acting hydraulic cylinder. The dual-acting hydraulic cylinder has a first working chamber defined by a first piston surface and a second working chamber defined by a second piston surface. The first working chamber is connected to first connections of the first and second hydraulic pumps. The second working chamber is connected to a second connection of the second hydraulic pump. A second connection of the first hydraulic pump is connected to a hydraulic fluid reservoir. The ratio of the first piston surface to the second piston surface differs from the ratio of the total delivery volume of the two hydraulic pumps relative to the delivery volume of the second hydraulic pump. A tapping valve for removing hydraulic fluid is provided for the volumetric flow equalisation.

  • Publication number: 20090064676
    Abstract: The invention relates to a hydrostatic drive comprising a first and a second hydraulic pump (11, 12) and a dual-acting hydraulic cylinder (2). The dual-acting hydraulic cylinder (2) comprises a first working chamber (7) and a second working chamber (8). The first working chamber (7) is defined by a first piston surface (4) of a working piston (3) and the second working chamber (8) is defined by a second piston surface (5) of the working piston (3). The first working chamber (7) is connected to a first connection (13) of the first hydraulic pump (11) and a first connection (14) of the second hydraulic pump (12). The second working chamber (8) is connected to a second connection (16) of the second hydraulic pump (12). A second connection (15) of the first hydraulic pump (11) is connected to a hydraulic fluid reservoir.
