SEAL ASSEMBLY
First Claim
1. A seal assembly for sealing a first space with respect to a second space, the seal assembly including a seal base body disposed on a first component and having at least first and second seal lips configured to run on a running surface of a second component, the second component having an axis of rotation extending in an axial direction, the first seal lip and the second seal lip being spaced from each other in the axial direction, the seal assembly further including at least one temperature-sensitive adjusting element disposed in the seal base body and configured to change shape in response to a temperature increase, wherein the temperature-sensitive adjusting element comprises a sleeve extending in the axial direction and being concentric to the axis of rotation, wherein one end of the temperature-sensitive adjusting element extends into a portion of the seal base body, wherein an other axial end of the temperature-sensitive adjusting element is spaced from the seal base body, wherein the seal base body includes a retaining section for retaining the one end of the temperature-sensitive adjusting element, the retaining section being configured as a bent section, wherein the retaining section holds the one axial end of the temperature-sensitive adjusting element or a retaining element to which the temperature-sensitive adjusting element is attached.

Abstract
A seal assembly for sealing a space between a first component and a second component includes a seal base body disposed on the first component and having at least first and second seal lips configured to run on a running surface of the second component with the seal lips contacting the second component at first and second axially spaced locations, the seal base body including an annular channel having an opening facing in the axial direction, and at least one cylinder comprising a bimetallic shape-change element, the cylinder having a first end in the annular channel of the seal base body and a second end outside the annular channel, at least a portion of the cylinder being located axially between the first seal lip and the second seal lip and radially inward or outward from the second seal lip.
