Abstract
An axial shaft seal for sealing a shaft against a housing of a combustion engine comprises a stiffening section and a sealing element connected to the stiffening section, having a sealing lip which is established for sealing interaction with a counter-running element which is connected to the shaft and runs radially. In the assembled state, a sealing contact exists exclusively between an end section of the sealing lip and the radial counter-running element. A plurality of channels is arranged on the side facing towards the counter-running element and over the periphery of the sealing lip, or on the counter-running surface and over the periphery of the counter-running element, in which a pressure build-up is caused when the shaft is rotating.
