Abstract
Den foreliggende oppfinnelsen viser en tetning mellom deler som er bevegelige i forhold til hverandre i en hydraulisk maskin, f.eks. et løpehjul og et hus som er tilnærmet tett og til tross for det meget enkelt oppbygget, og som utmerker seg ved at et tetningslegeme blir lagret på to hydrostatiske lågere.
