摘要

The throughput resistances (A1,A2) of the valve has a large hysteresis dependent upon the pressure in the pressure conduit (11). Under a first high pressure, the valve leaves its closure position and springs to an open position. It returns to its closure position at a closure pressure which is much less than the opening pressure. The opening pressure is 200 bars and the closure pressure is 3 bars. The valve maintains its opening pressure until the pressure drops to 40 bars. The opening surface of the valve body (1) effective in the opening direction in the closure position of the valve is very much smaller than a second opening surface effective in the opening position of the valve. ADVANTAGE - Independent of the link position in the event of a blocking cuts out the linkage aid and thereby reduces the pump power until a new link aid requirement is established.
