A hydraulic steering arrangement (1) is disclosed. The hydraulic steering arrangement (1) includes a supply port arrangement (P, T) having a pressure port (P) and a tank port (T), a working port arrangement having two working ports (L, R), a main flow path (2) having a main orifice (A1) and at least one further orifice (A2, A3, A4) downstream the main orifice (A1), the main flow path (2) being arranged between the pressure port (P) and the working port arrangement (L, R), a return flow path (4) arranged between the working port arrangement (L, R) and the tank port (T), a measuring motor (3), an amplification flow path (6) having an amplification orifice (AU) and being arranged between the pressure port (P) and the working port arrangement (L, R), and an adjustable pressure source (9) connected to the pressure port (P) and having a load sensing port (18), wherein a main drain orifice (Adrain) is connected between the main flow path (2) down-stream the main orifice (A1) and the return flow path (4). Such a steering arrangement should have the possibility of dynamic steering with a simple construction. To this end a dynamic main orifice (A1-dyn) is connected between the load sensing port (18) and the main flow path (2) downstream the main orifice (A1), and a dynamic drain orifice (Adrain-dyn) is connected between the load sensing port (18) and the return flow path (4), which dynamic drain orifice (Adrain-dyn) is open when the dynamic main orifice (A1-dyn) is closed.
