Title (EN) SEALING MEANS
(FR) MOYEN D'ETANCHEITE
Abstract: front page image
(EN)The invention discloses a sealing means including two properly spaced sealing faces. A plurality of holes are provided in the honeycomb-form on at least one of the sealing faces, so that under the action of fluid pressure or when the sealing faces move relatively to each other, the fluid in the holes forms whirl, which prevents the fluid from leakage and the sealing is achieved.
(FR)L'invention concerne un moyen d'étanchéité comprenant deux faces d'étanchéité espacées de manière adéquate. Plusieurs orifices en forme d'alvéole sont prévus sur au moins une des faces d'étanchéité de sorte que, sous l'effet de la pression de fluide ou lorsque les faces d'étanchéité se déplacent l'une par rapport à l'autre, le fluide à l'intérieur des orifices forme un tourbillon, ce qui empêche les fuites de liquides et permet d'assurer une étanchéité.
