Abstract

En sluseventilaktuator inklusive et hus, et stempel, en nedre endelukning og et stempelsylinderendedeksel. Stempelet er plassert inne i huset, og den nedre endelukningen kopler huset og stempelet. Stempelsylinderendedekselet kopler også huset og stempelet. Huset, stempelet, den nedre endelukningen, og endedekselet definerer et hovedaktuatorhulrom. Koplingen mellom den nedre endelukningen og stempelet og koplingen mellom stempelsylinderendedekselet og stempelet er koplinger som kan forsegles. Hovedaktuatorhulrommet er hovedsakelig isolert fra omgivende luft og fra et reguleringsfluid, som forhindrer fuktighetsopphopning og således forhindrer korrosjon av de indre komponentene av aktuatoren.
