Claims

[Claims for Utility Model Registration] (1) Seal rings 1, 3 located within the groove 11,
5 and back-up springs 2, 4, 6, when pressure is applied, the back-up springs 2, 4, 6 move against the seal rings 1, 4, 6.
A high-pressure seal characterized in that it moves in a direction protruding from the groove 11 by cooperation with the seals 3 and 5. (2) The surfaces of the seal rings 1 and 5 on the side of the backup springs 2 and 6 form tapered surfaces 1a and 5a in which the bottom side of the groove 11 is wider; The high-pressure seal according to claim 1, wherein the surfaces on the 1 and 5 sides are tapered surfaces 2a and 6a in which the bottom side of the groove 11 is narrower. (3) The surface of the seal ring 3 on the back-up spring 4 side forms a curved surface 3a in which the bottom side of the groove 11 is widened, while the surface of the back-up spring 4 on the seal ring 3 side forms a curved surface 3a where the bottom side of the groove 11 becomes wider. The high-pressure seal according to claim 1, which has a curved surface 4a that is narrower on the bottom side.
