Abstract

A seal arrangement for sealing a gap between two housing parts, the gap being situated between opposite end faces of the housing parts. In the first housing part, there is a first receiving groove on the first end face, in which first receiving groove a sealing strip is arranged which protrudes out of the receiving groove and lies against a first outer flank. The sealing strip engages in an opposite second receiving groove of the second housing part and lies against a second outer flank. For position securing purposes and to achieve a sealing effect, even if there is no differential pressure, a spiral strip is provided, which spiral strip is situated in the first receiving groove and exerts an elastic force on the sealing strip.
