Abstract (en)
[origin: EP1184576A1] The valve unit has a regulator piston (14), loaded via a control line (26,28,30) with the load pressure from the consumer. When a limit load pressure is exceeded, the piston is moved into a regulating position, in which a working connection (A) and a tank connection (S) are connected, and in which a pressure corresponding to the load pressure, acts on a piston end face (22). A measuring piston (32) is guided in the end face, and the piston has a radial bore (28) opening into an axial bore (26), to charge the measuring piston in closing direction, with the load pressure on the consumer.
