Abstract (en)
[origin: WO0246622A1] The invention relates to a locking block (1) for controlling a hydraulic consumer. A main piston (16) which is configured with an advanced opening can be lifted from a valve seat (26) in a return function, by means of an opening piston (68). A pressure chamber (76) which is delimited by the main piston on one side and by the opening piston on the other side is connected to a tank channel or low-pressure channel (8) for both the return function and the non-return function of the locking block, so that the changeover from the return function to the non-return function and vice-versa can take place very quickly.
