Abstract

The locking system has at least one cylinder (3), containing at least one piston (64) connected to a locking bolt (8), via a piston rod (7). The piston is actuated by hydraulic pressure supplied by pipes (4,5) from a control valve (6). A device (19) connects the opposite faces of the piston, and can be situated inside the piston. The device can also be built into the hydraulic circuit external to the cylinder, and may take the form of a connection of smaller cross-section than the supply pipes, and may also contain an aperture.
