Claim 18:
19. A seal arrangement for sealing a gap between a first housing part having a first end face and a second housing part having a second end face opposite the first end face; wherein the gap is defined between the end faces from an inside that lies on one side of the gap to an outside on an opposite side of the gap, wherein the seal arrangement is suitable for use with a lower media pressure on the outside and a higher media pressure on the inside; wherein in the first housing part, a first receiving groove is arranged which runs along the gap and opens towards the second end face and has a first outer flank pointing towards the outside; and wherein in the second housing part, a second receiving groove is arranged which is opposite the first receiving groove and has a second outer flank pointing towards the outside; the seal arrangement comprising:
a sealing strip which runs along the receiving grooves and has a flat form extending transversely to the end faces and bears against both outer flanks; and
an elastic helical strip, the center axis of which is arranged inside the first receiving groove and which extends along the first receiving groove and exerts a pressure force on the sealing strip;
wherein an outer end of the second outer flank at the second end face and an inner end of the second outer flank at an edge of a groove base of the second receiving groove are on opposite sides of an extension of the first outer flank.
