  • Patent number: 10640144
    Abstract: A hydraulic steering arrangement is shown having a steering unit and two working ports each of which being connected to the steering unit by a working line (3), wherein an anti jerk valve (9) is arranged in each working line (3), the anti jerk valve (9) having a valve element (12) being loaded in opening direction by the pressure in the working line (3) and in closing direction by restoring means (17). A vehicle equipped with such a steering arrangement should have a good comfort. To this end the valve element (12) is loaded in closing direction by the pressure in the working line (3) via delay means (21).

  • Patent number: 10625775
    Abstract: A hydraulic steering arrangement (2) is described having a main flow path (8) with a flow meter (9) and an amplification flow path (10) opening into the main flow path (8) at a connecting point (11) located between the flow meter (9) and a working port arrangement (L, R). Such a steering arrangement should have in a simple way a large flow of the hydraulic fluid to the working port arrangement. To this end pressure increasing means (17) are arranged in the main flow path (8) upstream the connecting point (11).

  • Publication number: 20070017731
    Abstract: The invention concerns a hydraulic steering arrangement with a hydraulically actuated steering valve arrangement, steering motor connections (CL, CR), which are connected to supply connections (HP, T) via the steering valve arrangement, and a steering unit. It is endeavoured to equalize in a simple manner the steering behaviour in both directions. For this purpose, it is ensured that the steering valve arrangement has a directional valve and a flow control valve.
