Abstract
In a seal arrangement between a stationary and a rotating machine part, for example, between a transmission housing and a hollow sleeve exiting from the housing, there are arranged two V-rings oriented concentrically to one another in the one machine part, the lips of the seals cooperating with the other machine part. To extend the service life of the seal arrangement, a first V-ring is first in an effective position and a second V-ring is supported for movement from a noneffective position (A) into an effective position (B) at a later time by means of a device which can be operated from outside.
