Seal arrangement for a split housing

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 a gap is defined between the end faces and an inside lies on one side and an outside on the opposite side, 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.
