Patent ID: 7959159

Claim:
A seal arrangement for sealing between a first medium space filled with a first medium and a second medium space filled with a second medium, wherein a moveable component, which is displaceable in the longitudinal direction thereof and/or rotatable about the longitudinal direction thereof, extends through the seal arrangement in an installed state of the seal arrangement and wherein the seal arrangement comprises a sealing element which comprises a first sealing region that is sealing in relation to the first medium space and a second sealing region that is sealing in relation to the second medium space, wherein the first sealing region comprises a first dynamic sealing section abutting against the moveable component in the installed state of the seal arrangement and the second sealing region comprises a second dynamic sealing section abutting against the moveable component in the installed state of the seal arrangement and at least one of the two dynamic sealing sections has at least two sealing lips, wherein each of the two sealing regions comprises at least one respective spring element which biases the dynamic sealing section of the respective sealing region against the moveable component in the installed state bf the seal arrangement, wherein the sealing element comprises a central web which is arranged between the first dynamic sealing section and the second dynamic sealing section and abuts a against the moveable component in the installed state of the seal arrangement, wherein at least one dynamic sealing section of the sealing element has a plurality of leakage storage spaces which are formed between two respective mutually neighboring sealing lips or between the respective sealing lip located closest to the central web and the central web itself, wherein the leakage storage spaces of the at least one dynamic sealing section are of different sizes, wherein the size of the leakage storage spaces of the at least one dynamic sealing section decreases with increasing distance from a medium-space end of the at least one dynamic sealing section, and wherein the internal diameter of the sealings which bound he leakage storage spaces increases with increasing distance from the medium-space end of the at least one dynamic sealing section in the uninstalled state of the seal arrangement.
