Abstract

Oppfinnelsen vedrører et aksiallager og en ^ellboremaskin tilveiebrakt med et aksiallager. Aksiallageret (100) innbefatter et første stempel (20) og et andre stempel (21). Aksielle kontaktoverflater (60, 43a) mellom stemplene (20, 21) er anordnet i det samme trykkrommet (28). Det samme trykkfluidet matet til aksiallageret virker på kontaktoverflatene og på arbeidstrykkoverflatene til stemplene.
