<p>The sealing arrangement has an air space (B) which is connected to the interior (A) in axial direction of the shaft (1) with connection to the atmospheric outside air. The sealing ring (3) has a traversing channel (9) which connects the interior with an annular space (A1) and in which a pressure compensation valve (10) is located. The pressure compensation valve opens in a predetermined over pressure in the interior related to the pressure in the annular space.</p> |
