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.

Abstract: A shaft seal configured to seal an oil space from a fuel space of an injection pump for an internal combustion engine coaxially and sealingly surrounds a rod configured to oscillate axially with respect to the shaft seal. The shaft seal is configured to seat in a bore of a housing of the injection pump in a sealing manner, and the shaft seal includes a first seal element to which a second seal element is axially connected. The first seal element and the second seal element are configured as substantially hollow cylinders and may be formed from different materials.

Abstract: 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.
