Abstract (en)
[origin: EP1083338A2] The arrangement has at least one dual action hydraulic working cylinder (1) joined to the vehicle and to the moving part with one working vol. (3) connected to a passive pressure reservoir (4) and the other (7) to a hydraulic pump (8). A non-return valve (11) between the working cylinder and pump is blocking towards the pump and a line to the tank (9) that branches off between the non-return valve and working cylinder contains an electrically driven proportional pressure valve (13) as a pressure limiting valve. An Independent claim is also included for a method of hydraulic actuation of a movable part in a vehicle.
