Abstract

Det er beskrevet et dentalt håndstykke som innbefatter en turbinkonstruksjon som danner en radiell innstramming av luft på impellerbladene langs hele omkretsen til turbinen. Dette danner ytterligere moment og unngår asymmetrisk trykk på impellerhjulet. Et par lagre med innbyrdes aksiell avstand understøtter turbinen. Lufttilførselen til lagrene er regulert på en slik måte at luftlagrene flyter før drivluften blir tilført til turbinen og etter at drivluften har blitt stengt av. Dette sikrer at luftlagrene alltid er operasjonelle uansett drifttilstanden til turbinen. Håndstykket har en forbedret ergonomisk form, spesielt formen og konfigurasjonen av fronten eller drivhodet, noe som gir ytterligere tannklaring og et bedre synsfelt. Det er tilveiebrakt en vinklet svivelkobling til navlestrengen, noe som reduserer fysiske påkjenninger på tannlegens håndledd. Det er også tilveiebrakt en selvjusterende momentkobling av lås- og nøkkeltypen som gir plass til både konvensjonelle bor og bor med lås- og nøkkelarrangementet. Det er beskrevet et autostopparrangement for turbinen som forhindrer at det bygges opp et vakuum under nedkjøring av turbinen. Den spesifikke utformingen av autostoppventilen i henhold til oppfinnelsen lukker både driv- og utstrømningsgassledningene.
