The invention concerns a hydraulic steering arrangement ( 1 ) with a supply connection arrangement (P, T), a working connection arrangement (A, B) connectable to a steering motor ( 5 ), a steering unit ( 6 ) located between the supply connection arrangement (P, T) and the working connection arrangement (A, B), and a steering valve ( 14 ) whose outlet is connected to the working connection arrangement (A, B). It is endeavoured to keep the load of such a steering arrangement small. For this purpose, the steering unit ( 6 ) is made as an open-center steering unit, an inlet ( 20 ) of the steering valve ( 14 ) being connected to a pressure supply arrangement ( 22 ) that can be activated by an activation of the steering valve ( 14 ).
