Abstract (en)
[origin: EP2339185A1] The control (H) has a pressure deflector (16) arranged in a relief duct (15) extending from a main line (P) to a tank (R). The deflector is subjected with control pressure, which is produced by a pump (P1) with a small delivery rate, in a switching direction towards a blocking position (17). The pump supplies the line. The pressure is derived from a pressure difference produced at a throttle (23). A cross-section of the throttle is adjusted to a small delivery rate so that the deflector is brought into the blocking position by activating the pump and another pump (P3) with temporal delay.
