Zusammenfassung:	A hydraulic steering arrangement (1) including a supply port arrangement having a supply port (2) and a return port (3), a working port arrangement having two working ports (4, 5), a supply flow path (7) between the supply port (2) and one of the working ports (4, 5), a return flow path (9) between the other of the working ports (5, 4) and the return port (3) and a valve arrangement having a spool/sleeve set, wherein the supply flow path (7) includes a supply orifice (A4) and the return flow path (9) comprises a return orifice (A5). Such a hydraulic steering arrangement should give a comfortable feeling when used in connection with an articulated vehicle. To this end a variable damping orifice (Adp) is arranged downstream the supply orifice (A4) and upstream the return orifice (A5).
