Abstract

Embodiments relate to a seal for sealing a valve shaft in an internal combustion engine. The seal includes a sealing lip of an elastomer which is configured to be in contact with a shell surface of the valve shaft perpendicular to a radial direction. The seal further includes a supporting structure firmly connected to the sealing lip and made of a material different from the elastomer of the sealing lip which is configured to create a form-fit in the axial direction directly between the supporting structure and a guide element of the valve shaft by an at least partial plastic deformation in the radial direction.
