Abstract

Trykkforsterker for montering ovenfor borekronen på et borerør for å frembringe et forhøyet væsketrykk i en del av en boreslamstrøm, omfattende et stempel (6) som er bevegbart i en sylinder (1,2,3). Stempelet har en stor stempelflate (11) og en motsatt liten stempelflate (12) som frembringer et forhøyet trykk i en mindre del av boreslatt\strømmen. En ventilanord- ning (4,24A,24B) styrer boreslamstrømmen til og fra sylinderen (1,2,3). En høy- trykkskanal (15) med en enveis ventil (15A) forbinder rommet foran den lille stempelflate (12) med en samlekanal (16) for boreslam under det forhøyede trykk. Stempelet (6) har også en annen stor stem- pelflate (13) vendt motsatt av den første store stempelflate (11) og innrettet til å påvirkes av boreslamtrykket i borerøret (10) for å bevege stempelet (6) i en mot- satt retning. En annen liten stempelflate (14) vendt motsatt av den første lille stempelflate (12) er innrettet til ved stempelbevegelsen i den motsatte retning å frembringe et forhøyet boreslamtrykk.
