<p>In air-spring legs with a pressure chamber for motor vehicles, in which the pressure chamber is subjectable to different pressures via a connector 2 leading to the outside, a minimum pressure is to be ensured in the chamber irrespective of external influences. For this purpose, the connector of the pressure chamber has an automatically operating valve by means of which the connector 2 is open at a pressure which is acting from the interior of the pressure chamber or from the outside and which is above the minimum pressure and, at a pressure below it, is closed. The closure element of the valve is a tubular elastomer 4 which is pulled onto a cylindrical basic body 3 and by means of which bores running through the basic body are separated from one another or connected to one another in terms of flow. <IMAGE></p> |
