Abstract[English]
A labyrinth seal (101) for sealing between a rotating portion (102) and a non-rotating portion (103) of rotating machinery, the labyrinth seal having a first portion (111) and a second portion (112). The first portion has a series of projections (117) and recessions (116) that are concentric about an axis of rotation of the rotating portion of the rotating machinery. The second portion has a series of projections (115) and recessions (118) that are concentric about the axis of rotation. The projections of the series of projections and recessions of the second portion are configured to mate with the recessions of the series of projections and recessions of the first portion. The projections of the series of projections and recessions of the first portion are configured to mate with the recessions of the series of projections and recessions of the second portion. The second portion includes a mount (119) having a substantially rigid layer (120) sandwiched between substantially compliant layers (121).[French]
La présente invention concerne un joint à labyrinthe (101) destiné à assurer l'étanchéité entre une partie rotative (102) et une partie non rotative (103) de machines tournantes, le joint à labyrinthe ayant une première partie (111) et une seconde partie (112). La première partie comporte une série de saillies (117) et de creux (116) qui sont concentriques autour d'un axe de rotation de la partie rotative de la machine tournante. La seconde partie comporte une série de saillies (115) et de creux (118) qui sont concentriques autour de l'axe de rotation. Les saillies de la série de saillies et de creux de la seconde partie sont conçues pour s'accoupler avec les creux de la série de saillies et de creux de la première partie. Les saillies de la série de saillies et de creux de la première partie sont conçues pour s'accoupler avec les creux de la série de saillies et de creux de la seconde partie. La seconde partie comprend un support (119) ayant une couche sensiblement rigide (120) prise en sandwich entre des couches sensiblement élastiques (121).
