Abstract
A hydraulic steering arrangement () is provided comprising a static steering unit () and an adjustable pressure source () connected to a pressure port () of said steering unit () and having a load sensing port (). Such a steering unit should enable a fast reaction of the steering unit. To this end said pressure source () is a dynamic pressure source having an orifice (Adyn) outputting hydraulic fluid to said load sensing port (), a load sensing line () connecting said load sensing port () and a low pressure port (), a control valve () being arranged in said load sensing line () between said load sensing port () and said low pressure port (), said control valve () being actuated by a control pressure within said steering unit () and throttling a flow through said load sensing line () depending on said control pressure.
