A shaft seal is proposed, having an annular base body whereof one lateral surface forms a circumferential sealing surface and whereof the other, opposing, lateral surface has at least two circumferential sealing lips extending radially therefrom, between which an outwardly open outer cavity is delimited. To enable a coupling between a stationary body and a rotatable body arranged coaxially thereto which is suitable for pressure-medium transmission, the shaft seal is distinguished by a pressure-medium inlet in an outer wall of the base body and a pressure-medium outlet which leads into the outer cavity and is in fluid connection with the inlet. |
