Abstract
A hydraulic steering arrangement () is described comprising 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 () having a main orifice (A), at least one further orifice (A, A, A) downstream the main orifice (A), and a measuring motor (), the main flow path () being arranged between the pressure port (P) and the working port arrangement (L, R), a return flow path () arranged between the working port arrangement (L, R) and the tank port (T), an amplification flow path () having an amplification orifice (A) and being arranged between the pressure port (P) and the working port arrangement (L, R), and an adjustable pressure source () connected to the pressure port (P) and having a load sensing port (), wherein a main drain orifice (A) is connected between the main flow path () downstream the main orifice (A) and the return flow path (). It should be possible to operate such a steering arrangement with a dynamic flow. To this end a flow divider () connects the load sensing port () with the main flow path () downstream the main orifice (A) and the amplification flow path () downstream the amplification orifice (A).
