THE INVENTION
The invention relates to a sealing ring which is defined in
representative claim 1 as follows:
1. A sealing ring comprising:
a toroidal supporting body having a longitudinal axis, and a
sloped, radially outer portion set at an angle with respect to
the axis, the sloped portion of the supporting body being bound
by two axially offset planes which define the axial extent of the
slope,
a sealing body comprising a dynamically stressed sealing lip
made of an elastomeric material which at least partially encloses
the supporting body, the sealing body having a sloped surface
facing the sealing lip, and the sealing body having a dynamically
stressed sealing bulge on the side of the sealing lip facing away
from a space to be sealed, said sealing bulge coming in tight
contact with the surface to be sealed under an initial elastic
stress, wherein the sealing bulge is arranged between the two
radial planes in the axial direction which border the slope
axially
wherein the sloped portion is in contact with the sealing
body and the portion which contacts the sealing body faces toward
the longitudinal axis of the toroidal supporting body.
