Abstract

Den foreliggende oppfinnelse angår en tetning for bruk til tetting av en roterende del av en tetning som er spesielt velegnet for å tette de stordiameterdeler av tromler som brukes i store vaske- og filtersylindere og akslinger i treforedlingsindustrien. Vedkommende vasker omfatter et stasjonært ytre skall (10), et matningskammer (12) for vaskevæske plassert inne i skallet, som er definert ved en perforert plate (16), og en roterende trommel plassert innenfor den nevnte over- flate (16) hvor trommelen har en væskegjennom- trengelig perforert overflate (18) hvorved det såkalte masserom (20) er definert mellom de nevnte perforerte overflater (16, 18), hvor vaskeren er utstyrt ved begge dens ender med en pakning for å tette den roterende trommel i forhold til det ytre skall, hvor terningen er utført ved en tetningsboks (26) og en tetningsdel plassert i den , og er et karakteristisk trekk ved den nevnte vasker at tetningsboksen (26) er utstyrt med en anordning (40) for å innføre et rrykkmedium, fortrinnsvis væske, inn i tetningsboksen (26).
