Abstract

A találmány tárgya hidrodinamikai tengely tömítő elrendezés (10). Atalálmány lényege abban van, hogy az alábbi elemekből áll: hordozóelem (14); tömítő elem (12). A tömítő elemen (12) legalább egyhidrodinamikai horony van kiképezve, amelynek van egy nyitott csatornarésze és legalább egy rugalmasságnövelő bevágott része, amely anyitott csatorna résztől a tömítő elembe nyúlóan van kiképezve atömítő elem (12) rugalmasságát növelendő. A találmány tárgya mégeljárás legalább egy spirális hidrodinamikai jellemző létrehozásárapolitetrafluoretilén tengelytömítő elemben, melynek lényege abban van,hogy politetrafluoretilén tömítő elemet (12) hoznak létre, amelynektömítő felülete van, és a tömítő felületnek azon a részén, amely atengely felé esik, spirális nyitott csatornás hidrodinamikai részthoznak létre, és létrehoznak spirális rugalmasságnövelő zárt bevágottrészeket, amelyek a spirális nyitott csatorna részből indulnak.
