Abstract

Official abstract text for this publication.

A split seal ring includes: an annular main body seal split partially in a circumferential direction; and abutment surfaces provided on split surfaces of the main body seal so as to be joined to each other. Each of the abutment surfaces includes: a first inclined surface extending in a direction intersecting with the circumferential direction; a first horizontal surface extending from one end side of the first inclined surface along the circumferential direction; and a second inclined surface extending from an end of the first horizontal surface opposite to the first inclined surface in the direction intersecting with the circumferential direction. With this configuration, there can be provided a split seal ring having a structure that can improve the sealing performance.

First claim

Opening claim text (preview).

The invention claimed is: 1. A split seal ring comprising: an annular main body seal split partially in a circumferential direction; and abutment surfaces provided on split surfaces of the annular main body seal so as to be joined to each other, each of the abutment surfaces including: a first inclined surface extending in a direction intersecting with the circumferential direction; a first horizontal surface extending from one end side of the first inclined surface along the circumferential direction; and a second inclined surface extending from an end of the first horizontal surface opposite to the first inclined surface in the direction intersecting with the circumferential direction, said annular main body seal having a radial inner circumferential-side side surface with inner protruding portions protruding radially inward from said radial inner circumferential-side side surface, where number of the inner protruding portions are identical to number of the inclined surfaces, and said annular main body seal having a the radial outer circumferential-side side surface with outer protruding portions protruding radially outward from said radial outer circumferential-side side surface, number of the outer protruding portions being identical to number of the inclined surfaces. 2. The split seal ring according to claim 1 , wherein each of the abutment surfaces includes: a second horizontal surface extending from one end side of the second inclined surface opposite to the first horizontal surface along the circumferential direction; and a third inclined surface extending from an end of the second horizontal surface opposite to the second inclined surface in the direction intersecting with the circumferential direction. 3. The split seal ring of claim 1 , wherein said inner protruding portions are symmetrically oriented with respect to said outer protruding portions. 4. The split ring of claim 1 , further comprising a first axial face and a second axial face, said first axial face and said second axial face extending between said radial inner circumference-side surface and said radial outer circumference-side surface and configured for receiving an axial compression force.
