Abstract: The invention relates to a hydraulic steering device that hydraulically connects a steering cylinder to a supply system, whereby the supply system is hydraulically operatively connectable to the steering cylinder via a steering valve to form a main flow connection and the supply system is hydraulically operatively connectable to the steering cylinder via a flow regulation valve arrangement to form a branch flow connection that circumvents the main flow connection, whereby the flow regulation valve arrangement is triggerable by an electric control unit and the flow regulation valve arrangement comprises valve groups that are triggerable individually, which are respectively connected in the forward flow and return flow of the branch flow connection and a release-shutoff valve is assigned to the flow regulation valve arrangement. It is provided that the release-shutoff valve is connected between the flow regulation valve arrangement and the steering cylinder.

Abstract: The invention relates to a hydraulic steering facility for mobile systems, with a steering circuit for a steering facility and a working circuit for a working hydraulic system, whereby the steering circuit and the working hydraulic system are connected to a supply pump via a shared flow dividing valve and the flow dividing valve is connected to a load signal connection of the steering device. It is provided that the steering facility has an adjustable input choke that is connected via an inflow connection of the steering facility to the flow dividing valve, between the load signal connection and downstream of the input choke, a parallel circuit consisting of a choke and an adjustable second load signal choke is arranged, and the load signal connection is further connected via an adjustable first load signal choke to a return flow connection of the steering facility.

Abstract: A hydraulic steering device which hydraulically connects a steering cylinder to a supply system. The supply system is hydraulically operatively connectable to the steering cylinder via a steering assembly for the purposes of forming a main flow connection, and the supply system is furthermore hydraulically operatively connectable to the steering cylinder via a flow regulating valve arrangement, such that a secondary flow connection can be formed which bypasses the main flow connection and via which at least one first working chamber and one second working chamber of the steering cylinder can be supplied independently of one another with hydraulic fluid.

Abstract: A hydraulic steering device hydraulically connects a steering cylinder to a supply system, wherein the supply system can be operatively connected hydraulically to the steering cylinder via a steering valve in order to configure a main flow connection, and the supply system can be operatively connected hydraulically to the steering cylinder via a flow control valve arrangement in order to configure an auxiliary flow connection which bypasses the main flow direction.
