<p>Apparatus for automatically or remotely dividing a two pump unit hydraulic steering system, upon detection of dangerous loss of fluid, into two independent steering systems in order to maintain steering capacity utilises an isolation valve (10) for blocking interconnecting piping (11, 12) in conjunction with by-pass valves (15, 16) for relieving resistance by one ram group (24) to motion of another (25). The valves (15, 16) and the pump units (13, 14) are regulated automatically or remotely by a control unit (21) in response to detection of fluid loss to achieve steering by the ram group on the loss-free side.</p> |
