Abstract
A sealing device between two axisymmetric coaxial parts, includes an elastic segment, two holding elements located on each side of the annular segment, an annular spacer arranged between the two holding elements, wherein the annular spacer has a notch around its peripheral rim; the annular elastic segment has a hooking element at each of its free ends, adapted to cooperate with the notch of the annular spacer, and to hold the elastic segment in a pre-holding position by elastic return force.
Claims10
A sealing device between two axisymmetric coaxial parts, said device including:
- an annular elastic segment with an angular opening;
- two holding elements located on each side of said annular segment and adapted to hold said segment in position axially while allowing a limited axial displacement;
- and
- an annular spacer arranged between said two holding elements and adapted to hold said two holding elements at a given spacing;
- wherein said annular spacer has a notch around its peripheral rim;
- and
- wherein said annular elastic segment has a hooking element at each of its free ends adapted to cooperate with said notch of said annular spacer, and to hold said elastic segment in a pre-holding position by elastic return force, in which an outside diameter of said elastic segment is less than the outside diameter of said elastic segment when the elastic segment is in its free state and in which a central axis of said elastic segment is offset from the central axis of said annular spacer.
