Abstract (en)
[origin: EP2466153A1] The device (H) has a multi-position multi-way slide valve which is a spool valve (W) that is arranged between tank assemblies (P,R) and working lines (9,10) of hydraulic motor (M) with pressure pilot control units (15,16) and pressure reducing valves (3,4). Controlled pressure signals (Pst1,Pst2) are applied after adjusting the valve to a floating position, and applying current signals (PE01,PE02) to pilot control units. The spool valve is switched between an open neutral position of tank and a floating position by simultaneously applying current to pilot control units.
