PCT No. PCT/DK93/00390 Sec. 371 Date Jun. 6, 1995 Sec. 102(e) Date Jun. 6, 1995 PCT Filed Nov. 30, 1993 PCT Pub. No. WO94/13958 PCT Pub. Date Jun. 23, 1994A hydraulic system is proposed, with a pressure source (P), a pressure sink (T), a work motor (4), a main valve (3) which is arranged between the pressure source (P) and the pressure sink (T) on the one hand and the work motor (4) on the other hand and is connected to the work motor (4) by way of work connections (73, 74), and a compensating valve (2) between the pressure source (P) and main valve (3) and an additional valve arrangement (5) between the main valve (3) and the pressure sink (T), which controls the volume flow from the main valve to the pressure sink (T). In a system of that kind it is desirable to provide better control facilities. To that end, the valve arrangement (5) has an externally controllable degree of opening. |
