Abstract:
Hydraulic steering (1) is disclosed comprising a high pressure port (P), a low pressure port (T), two working ports (CL, CR), a manual steering section (3), and a steering valve section having a steering valve 5 and a hydraulic driving arrangement (6) adjusting hydraulically a position of said steering valve. A change from automatic steering to manual steering should be reliably ensured when the manual steering section is directly influenced by a driver. To this end, a switching valve (11) is provided, which is actuatable between a first position in which said driving arrangement (6) is supplied with hydraulic fluid under pressure, and a second position in which a supply of hydraulic fluid to said driving arrangement (6) is interrupted, wherein said switching valve (11) is hydraulically actuated into said second position by a pressure generated upon actuating of said manual steering section (3).
