Abstract

A method of setting a position and/or springing properties in shock or vibration dampening with the aid of one or more piston-cylinder devices. Dampening is achieved by a first liquid (7) being caused to flow, as a result of movement of a piston (3), between the spaces which are connected by at least one constriction (8). Springing is partially provided by the liquid being allowed to co-act with a first gas cushion (9). The piston (3) is acted on by the first liquid (7) on one side, and on the other side by a second gas cushion (12) and/or a second liquid (13) in or external to the cylinder bore, when external preferably forming a second gas cushion (12). The position of the piston is set by changing the amount of the first liquid in the cylinder bore and/or by changing the amount of the second liquid or gas cushion. The springing properties are varied by varying the amount of gas in the first and/or the second gas cushion. In addition, a piston-cylinder device for this purpose, in which an annular chamber (6) round the piston rod (4) is included in a flow system which encloses the above-mentioned first liquid (7), whereby the annular chamber constitutes one of said spaces.
