Abstract

The small dia. piston fits in a cylinder housing and is operated by a piston rod. The transmission device fits between the piston and the rod and two settings are provided for a loaded and unloaded vehicle. The transmission device may consists of two angled levers with different lengths of lever arm. The locking mechanism, to exclude one of the levers, consists of a positional piston operated by a pressure valve. The levers may operate pistons. alternatively two separate hydraulic pistons of different dimensions operate from the same pressure container.
