Abstract

The balancing device has a single acting pneumatic cylinder in which slides a piston with a certain clearance providing a leakage path. The piston is connectd by a link to a movable element, the cylinder being supplied with air through an expansion valve. The cylinder is pref. parallel to the path of the movable element, the link being in the form of an endless line passing through the piston and over pulley at the ends of the cylinder. The line is pref. tensioned by springs acting between the cylinder and the pulley supports.
