Abstract
Garniture d'étanchéité coulissante pour pistons et tiges de piston, constituée par une combinaison de bagues d'étanchéité et de graissage. Au moyen d'une multiplication de pression à l'intérieur de la garniture combinée, par un serrage axial avec écartement radial par un serrage radial et/ou une armature textile spéciale de la bague d'étanchéité elle-même on obtient une pression partielle élevée qui impose une marche pratiquement absolument à sec de la garniture combinée, tandis qu'entre la bague d'étanchéité et le flanc de rainure éloigné de l'espace sous pression est montée une bague cn matière plastiquement déformable et non autolubrifiante contenant une proportion importante de lubrifiant sec minéral. L'invention est applicable entre autres à des vérins et accumulateurs de pression.
