description A hydraulic steering control unit (1) is provided comprising a supply port arrangement having a supply port (P) and a return port (T), a working port arrangement having two working ports (L, R), a load sensing port (LS), a main flow path (14) being arranged between said supply port (P) and one of said working ports (L, R) and including a flow meter, a return flow path (16) arranged between the other of said working ports (L, R) and said return port (T), an amplification flow path (17) being arranged parallel to said main flow path (14), and a main load sensing path (19) connecting said load sensing port (LS) with said main flow path (17) and being connected with said return port (T) via first drain orifice means (A1dr). It is intended to have a flow amplification in a steering unit using dynamic load sensing even in slow steering mode. To this end a second load sensing path (21) connects said load sensing port (LS) to said amplification flow path (17) downstream said flow meter.
