26 of the sealing ring 2 which faces the high pressure side h the pretensioning element 3 that is clamped between the two groove flanks 51 and 52 abuts the rear side flank 26 of the sealing ring 2 thereby adjusting the axial force component 220 and ensuring abutment of the sealing ring 2 on the groove flank 51 on the low pressure side the embodiment of the sealing arrangement 1 shown in fig6 is characterized by a relief channel 6 u2032 which extends along the outer surface 21 and the rear side flank 26 of the sealing ring 2 and is not closed by the pretensioning element 3 in the illustrated pressure free state but terminates in a partial space 54 of the groove space 5 on the low pressure side the partial space 54 is limited by the groove flank 51 on the low pressure side the groove bottom 53 and the pretensioning element 3 the sealing ring 2 abuts the groove flank 51 on the low pressure side via an additional sealing edge 52 limits the partial space 54 by this additional sealing edge 25 and prevents connection between the partial space 54 as well as the relief bore 6 that terminates therein and a space that joins the low pressure side n or the low pressure side n the sealing ring 2 seals in an axial direction 220 via the additional sealing edge 25 and in a radial direction 210 via the sealing edges 20 and 20 u2032 by means of the force 200 exerted on the sealing ring by the pretensioning element 3 that abuts its outer surface 21 that is oriented at an inclination fig7 shows.
