Combination seal for sealing between two machine parts

In a double wiper arrangement, a wiper ring (5) and a stressing ring (6) are arranged in a groove (4) of a width which is only little larger than the width of the wiper ring (5). The stressing ring (6) loads the wiper ring (5) through a shoulder and an inclined circumferential surface (14) in such a manner that the wiper ring (5) is retained in contact with the flank (17) of the groove (4) on the high-pressure end and that a contact pressure is produced along a flat surface portion (7) which pressure diminishes at least nearly linearly along the said flat surface portion, starting from its inner end, but which is still defined at the outer end thereof.
