Abstract (en)
[origin: EP1355065A1] The hydraulic control system includes a hydraulic motor (10) connected to a control valve which is connected to a low-pressure connection (T) and, via a compensating valve, to a high-pressure connection (P). A return flow compensating valve (14,15) is installed in each working line, each valve having a flow characteristic line which extends towards the flow characteristic line of the compensating valve (4) without intersecting. The flow characteristic lines of the return flow compensating valves are equal, and the flow characteristic lines of the return flow valves and compensating valve may be parallel.
