Turbine seal, comprising:
- (a) an outer tubular element,
- (b) an inner tubular element, the elements being concentric and radially spaced,
- (c) a first ring joined to the outer tubular element, the ring having an inwardly-directed groove,
- (d) a second ring joined to the inner tubular element, the ring having an outwardly-directed groove, each groove of the first and second rings being with spaced, parallel radial surfaces, and
- (e) a junction element in the form of a washer having an outer peripheral edge lying in the inwardly-directed groove and an inner peripheral edge lying in the outwardly-directed groove, the edge of the junction element lying in each groove having an annular enlargement of circular cross-section that fits snugly between the radial surfaces, the grooves in the first and second rings having a depth in the radial direction that is at least greater than the minor diameter of the enlargement.
