The invention concerns a hydraulic steering arrangement (,) with an adjustable throttle, which has an internal rotary slide (,) with internal steering openings (,) in its circumferential wall and rotatable in relation to this, an external rotary slide (,) with external steering openings (,) in its circumferential wall (,).
