Claim 0:
1. A ring seal for sealing a gap between two parts that can be moved axially relative to one another, having
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
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 the sealing surface has a first central section (I) having, in the cross-sectional profile, a radius R of R<B/2 with respect to an axial width B of the ring seal,
wherein the sealing surface further has a second and third section (II, III) which enclose the first central section (I) between them,
wherein the sealing surface in the region of the second and third sections (II, III) is embodied as a planar annular surface in each case, which is aligned at an angle (α) of 60 to 85 degrees with respect to the axis of symmetry (S) of the cross-sectional profile,
wherein starting from the second and third sections (II, III), the sealing face transitions into a side face in each case,
wherein the side faces are oriented at an angle (β) of 5 to 30 degrees to the axis of symmetry (S),
wherein the ring seal is tapered in a region between the side faces and the groove base area, and
wherein the region of the ring seal that is tapered is formed by two opposing concave recesses and thereby has a reduced width (B2) at a narrowest point of the region of the ring seal that is tapered.
