Abstract (en)
[origin: EP2280179A2] The arrangement has a releasable blocking valve (10) provided in a working passage (14). A pressure-relief unit relieves pressure in the working passage if the working passage is blocked toward a discharge passage (18) by a valve spool (22) of a directional control valve (8). An intermediate space is formed between the blocking valve and a control edge (40) of the valve spool, and connectable with the working passage when the discharge passage is blocked by the control edge of the of the valve spool.
