    Abstract: A continuously adjustable levelling column for chairs comprises a guide tube having a lower end and an upper end. A telescopic tube is guided within the guide tube and has a tapered upper end portion extending beyond the upper end of the guide tube. A gas spring is accommodated within the telescopic tube. This gas spring is axially fixed within the telescopic tube. The upper end of a container of the gas spring abuts through a distance piece a support face at the upper end of the tapered portion of the telescopic tube. A piston rod passing through the lower end of the gas spring is axially fixed with respect to the lower end of the guide tube. A locking control pin extends through the upper end of the gas spring and is engageable through a transmission pin by a control handle.

    Abstract: In the illustrative embodiment of the invention as described an engine bonnet is articulated to the framework of a motor car. A pneumatic or gas spring is articulated to both the framework and the bonnet. The gas spring balances part of the weight of the bonnet when the bonnet is to be opened by hand. In case of an accident the framework and/or the bonnet may be crushed in longitudinal direction of the car. In such case the piston rod of the gas spring is pushed inward of the cylinder beyond the normal innermost operational position and a retaining device becomes effective so as to prevent the piston rod from returning towards its outermost operational position.

    Abstract: In a steplessly adjustable hydropneumatic device the spring chamber of which is arranged at the piston rod exit end and which works with a liquid locking, a very simple hydraulic locking is obtained even for high traction stressing upon the piston rod in that both an annular separator piston and the partition are arranged in the inner chamber of the container, which is penetrated by the piston rod. For the hydraulic traction locking in the case of traction forces exerted suddenly upon the piston rod a valve device is provided which cooperates with the piston rod.

    Abstract: For a temperature-compensated gas spring, which consists of a container in which a concentrically arranged cylinder is arranged, where a main pressure chamber is separated in sealing manner from an auxiliary pressure chamber by a piston which is connected with a piston rod, a damping arrangement is provided for controlling the outward thrust speed. This is effected in that a damping chamber is arranged in which a damping piston provided with damping valves slides, the damping piston being arranged on an auxiliary piston rod which is in axially fixed connection with the piston rod.
