Abstract

Aksialtrykkgiver (l) eller truster beregnet for å bevirke et tilleggs- aksialtrykk mot et boreverktøy i enden av en borestreng hvor det særlig inngår et endeløst, slankt drivrør som kan trekkes ut fra en kveil, og denne giver (1) har et rørformet hus som består av en øvre sylinder (10) og en mellom- sylinder (25), et stempel (5) som kan bevege seg aksialt i en gjennomgående boring (6, 28) i huset, og en utskyvbar. nedre sylinder (40) som aksialt flukter med huset og er ført inn i boringen for forbindelse med stempelet. Borefluid under trykk kan føres gjennom trykkgive- ren, og det er anordnet dreiningssperrer for å hindre at den nedre sylinder drei- er seg i mellomsylinderen. Når borefluid settes under trykk i giveren presser fluidet mot stempelet (5) og skyver den nedre sylinder (40) fremover i samme retning som strømmen av fluidet.
