Abstract

As a special feature the labyrinth packing has axially displaceable, co-rotating packing rings (4), which are sealed against the shaft or sleeve (1) by means of a cap-like gasket (5). Thus, the co-rotating packing rings can be automatically adjusted in the annular gap. However, this would mean that they would be forced against one side of the gap by the overpressure, which is to be avoided. This is achieved in that on the low pressure sealing surface chambers (43) are formed, which are connected via bores (44) with the overpressure side. The medium against which sealing is to take place consequently passes through these bores into the chambers and a centrifugal action builds up a pressure acting counter to the overpressure, so that rings (4) "float" in the annular gap. <IMAGE>
