Abstract

En aktuator for omdannelse av lineær bevegelse til rota-sjonsbevegelse omfatter et trykkammer for å motta et arbeidsfluid, et aktuatorhus (1) forsynt med et langsgående spor (2), en åkramme (3) som er anordnet i huset (1), en aksel (B) som er ført gjennom det langsgående spor og inn i åkrammen, en trykktapp (4) montert på akselen () inne i åkrammen (3), returmidler (12) for å motvirke arbeidsfluidtrykket, og en over-styringsanordning (7, 9) på avstand fra trykkammeret som muliggjør at krefter som er lagret i aktuatoren kan frigjøres i tilfelle av aktuatorsvikt.
