    Abstract: The invention relates to a hydraulic drive (1), in which the hydraulic fluid makes a smooth transition between two displacement machines that are configured as two vane-type pumps, comprising a radially displaceable first impeller (3) that comprises first displacement bodies (6) and a second impeller (4) that comprises radially displaceable second displacement bodies (8), the first impeller (3) being located inside the second impeller (4) and the first displacement bodies (6) of the first impeller (3) being guided along a cylindrical running surface (9) of the surrounding second impeller (4). At least one first working chamber (10) is configured between the two impellers (3, 4) and one second working chamber (13) is configured between the second impeller (4) and a guide body that surrounds the latter (11). The second impeller (4) comprises at least one radial connection channel (15) for connecting the flow between the first and second working chambers (10, 13). To improve the efficiency of the drive, the second impeller (4) and the guide body (11) are interconnected in a rotary manner and the second displacement bodies (8) are guided in a radially displaceable and/or pivotable manner on the exterior of the second impeller (4) and/or on the interior of the guide body (11).

    Abstract: In a rotary positive displacement pump or motor the axial length L of a working chamber is varied by means of capacity change members (4, 10). Thereby a stepless change of capacity is achieved. A hydrostatic transmitting system composed of such designed axial variable capacity pump for use in a vehicle has advantages in all aspects of operation performance over current hydro-mechanical transmitting systems. Production costs, volumes and weights are lower than that of corresponding mechanical transmitting systems, and the transmitting efficiencies are higher than that of hydro-mechanical transmissions and close to that of mechanical transmissions.

    Abstract: The system for converting a linear motion into a rotational motion is characterized in that it comprises two hydraulic converters, integrated with a common compensating reservoir (1) filled with a working liquid, which are connected to a gear rack mechanism of the rotational motion. Each converter is comprised of a hydraulic pump consisting of vertical cylinders, the first (4) and the second (5), and of a hydraulic transmission, whereby this hydraulic transmission is comprised of passive horizontal cylinders, the first (2) and the second (3), which are hydraulically coupled in a controllable manner. The first piston rod (17) and the second piston rod (18) depict guides corresponding to the first horizontal piston (8) and the second horizontal piston (9) of the transmission. These guides transfer the liner motion of the first horizontal piston (8) and of the second horizontal piston (9) into a rotational motion of the working wheel (32) that is rotationally mounted on the frame, whereby this working wheel (32) is connected to the driven unit.
