Abstract
The invention relates to a ring seal for sealing a gap between two parts that can be moved axially to one another, with a cross-sectional profile, which is constant in the circumferential direction and has a symmetrical design with respect to a radially oriented axis of symmetry (S), and with a dynamic sealing surface arranged radially outside or radially inside on the cross-sectional profile, and a groove base area arranged radially opposite the sealing surface, wherein that the sealing surface has a first central section (I) which, in the cross-sectional profile, has a radius R of R<B/2 with respect to an axial width B of the ring seal, and the sealing surface further has a second and third section (II, III) which enclose the first central section between them, and that the sealing surface in the region of the second and third sections (II, III) is in each case embodied as a planar annular surface which is oriented at an angle (α) of 60 to 85 degrees with respect to the axis of symmetry of the cross-sectional profile.
