Abstract
The invention concerns a hydraulic steering arrangement (1) with an adjustable throttle, which has an internal rotary slide (2) with internal steering openings (4) in its circumferential wall and rotatable in relation to this, an external rotary slide (3) with external steering openings (7, 10) in its circumferential wall (8). The production of such steering arrangements must be inexpensive, yet a jamming during operation must be avoided. For this purpose, each of the external steering openings is made by a substantially radially extending bore (7), which penetrates part of the circumferential wall (8), and a following section (10) with reduced flow cross section.
