Abstract (en)
[origin: EP0994261A2] In order to fasten the lid and operate it in at least one direction on an emergency basis, the two work chambers (2,3) of the lids are joined to one another by a connecting pipe (12), which contains a blockable check valve (13). The valve constituent of the check valve is blockable by a hydraulically-operated control piston with a larger surface than a valve seat. A throttle (15) is installed in the pipe (4) leading to one of the work chambers of the work cylinders. The unblockable check valve opens in its unblocked state in the direction of the rod side (2) of the work cylinders on the piston side (3).
