Abstract: Disclosed is a control device for a hydraulic steering device, having a control input device and an electrically operable valve for actuating a steering actuator of the steering device, which valve can be electrically actuated as a function of steering setpoint values detected at the control input device via at least one first control path between the control input device and the valve, wherein the control device is set up in such a way that the relevant first control paths can be deactivated as a function of steering setpoint values detected at the control input device via respective second control paths, which are assigned to this relevant first control path and differ at least partially from the respective first control paths when this first control path is active, or can be activated when this first control path is deactivated.

Abstract: A hydraulic steering device having a steering actuator (10), which can be actuated by a steering unit (12), and having a flow-regulating valve arrangement (14), which is also used to actuate the steering actuator (10), is disclosed, which is characterized in that the flow-regulating valve arrangement (14) has a discharge valve (V2), which is designed as a proportional servo valve (16), and a directional valve (V3), which, in its unactuated position, blocks the fluid-conveying connection between the discharge valve (V2) and the steering actuator (10) and, in its actuated position, actuates the steering actuator (10) in one or the other steering direction.

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.

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: 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.
