Hydraulische Anordnung zur Betätigung von beweglichen Teilen an Fahrzeugen und Vorspannventil für diese Anordnung

摘要

On the piston side and ahead of the second valve-nozzle-assembly (6,10), a pair of non-return valves (14,15) in parallel opposition, is connected into the pressure line. The non-return valve (15) opening towards the tank (3) is implemented (equipped with spring biasing) as a pre-pressurization valve.
