Abstract
Устройство, размещаемое на пробке для закупоривания труб, которые предназначены для транспортирования жидкостей или газов, содержащее несколько скользящих плашек (15), располагаемых на периферии пробки с возможностью подъема вдоль конического упорного кольца (25) под воздействием гидроцилиндра (5). Скользящие плашки (15) имеют возможно разделенную поверхность (21, 21') скольжения и по меньшей мере одну возможно разделенную поверхность (20, 23) скольжения, угол наклона которой относительно продольной оси пробки отличен от угла наклона поверхности (21, 21') скольжения. Упорное кольцо (25) имеет поверхности (27, 29, 29', 31) скольжения, которые соответствуют поверхностям (21, 21', 20, 23) скольжения скользящих плашек. Первая часть поверхностей (20, 23, 27, 31) скольжения имеет крутой наклон, а вторая часть поверхностей (21, 21', 29, 29') скольжения имеет пологий наклон.Международная заявка была опубликована вместе с отчетом о международном поиске.
