Description

technical field

[0001] The invention relates to a radial shaft seal for sealing two media, which has two radial shaft seal rings which are designed to be identical and can be plugged into one another. Background technique

[0002] A shaft seal for sealing two media by means of two radial shaft seal rings is known from DE 2351767, wherein at least one seal ring has a housing that is angled in cross section, so that the seal rings can Plugged into each other, in this type of sealing arrangement a negative pressure or a positive pressure can build up between the sealing lips, so that venting is required from the cavity formed by the sealing rings. For this reason, the known shaft seal has radially and axially extending channels in the region of the housing surfaces where the two radial shaft seal rings contact each other. In this way, the air-inflated portion and the air-vented portion are formed. Overall, however, the seal has a very complex structure and requires a large am...
