SEAL FOR SEALING A VALVE SHAFT, TOOL AND METHOD FOR MOUNTING A SEAL TO A GUIDE ELEMENT OF A VALVE SHAFT

Embodiments relate to a seal (200) for sealing a valve shaft in an internal combustion engine. The seal (200) comprises a sealing lip (205) of an elastomer (210) which is configured to be in contact with a shell surface of the valve shaft perpendicular to a radial direction. The seal (200) further c...

Zusammenfassung:	Embodiments relate to a seal (200) for sealing a valve shaft in an internal combustion engine. The seal (200) comprises a sealing lip (205) of an elastomer (210) which is configured to be in contact with a shell surface of the valve shaft perpendicular to a radial direction. The seal (200) further comprises a supporting structure (215) firmly connected to the sealing lip (205) and made of a material different from the elastomer (210) of the sealing lip (205) which is configured to create a form-fit in the axial direction directly between the supporting structure (215) and a guide element (220) of the valve shaft by an at least partial plastic deformation in the radial direction.
