Abstract
A sealing ring for sealing a space between two substantially cylindrical space surfaces (36, 44) axially introducable one into the other comprises two annular sealing portions (2, 4) concentrically connected with each other. The sealing portions have one sealing surface (14, 16) each adapted to engage one space surface (44, 36) each. In its relaxed condition the sealing ring forms a recess (22) between the sealing portions (2, 4) and when this recess (22) is closed substantially without a compression of the sealing ring, the sealing surfaces (14, 16) take a substantially parallel position in relation to the space surfaces (44, 36), respectively. This provides that the sealing ring will at the compression between the space surfaces (44, 36) be subjected to a substantially uniform compression over the main part of its section.
