Abstract
Una disposición perfeccionada de junta hermética laberíntica entre un miembro estacionario y un miembro rotatorio que se extiende a través de dicho miembro estacionario, caracterizada por una ranura rebordeada dispuesta circunferencialmente, formada en dicho miembro estacionario teniendo rebordes de dicha ranura una superficie radialmente interior sobre ella con relación a dicho eje de dicho miembro rotatorio, un miembro de lecho flexible alojado dentro de dicha ranura de manera que dicho eje de dicho lecho está dispuestos circunferencialmente alrededor de dicha ranura, flexionándose dicho lecho para acomodarse a la curvatura de dicha ranura, miembros de tira flexible montados por los bordes sobre dicho miembro de lecho, estando montado dicho miembro de tira sobre dicho miembro de lecho de una manera ondulante para permitir el doblado de dicho miembro de lecho, variando la amplitud de dichas ondulaciones cuando el miembro de lecho es doblado para acomodarse a dicha ranura, y porque están previstos medios de refuerzo para empujar a dicho miembro de leche a contacto contra dicha superficie radialmente interior sobre dicho reborde de dicha ranura.
