Abstract

Det beskrives en fremgangsmåte og anordning for forandring av hastigheten til en borkrone nedhulls i en fluidaktuert motor, inkludert en fortrengningsmotor og en hydraulisk motor. Anordningen omfatter en omløpsventil som er installert i motoren for regulering av strømning gjennom og rundt drivseksjonen av motoren. Når den er stengt, tvinger omløpsventilen alt fluid til å strømme gjennom drivseksjonen av motoren, hvilket tildeler maksimum hastighet til borekronen. Når den er åpnet, tillates en andel av fluidstrømmen å strømme rundt drivseksjonen av motoren, hvilket reduserer hastigheten til borkronen. Omløpsventilen kan åpnes eller stenges mekanisk, elektrisk, hydraulisk, pneumatisk eller ved hvilke som helst andre midler, inkludert en uttakbar plugg.
