Zusammenfassung:	The hydraulic system for controlling a support contains a high-pressure main feed line, a main discharge line and a control-pressure main line. The main line is connected to the lower piston space of the prop via a distributor. The distributor is connected by the line to the lower piston space and by the line to the main line. A distributor has been fitted into the system, which distributor is connected by the line to the main line and by the line to the main line. The outlet of the distributor is connected via a valve and lines to the lower piston space. The distributors are controlled hydraulically by means of the hand distributor. The inlets of the distributor are connected to the main lines and the outlets to the control main lines, which are accordingly connected by the lines to the control elements of the distributors. The control elements of the distributors are connected by the line to the line connecting the main lines to the upper piston space, and the control element of one of the distributors is connected by the line to the line which connects the lower piston space to the main line.
