Abstract

En turbin (3) for energiproduksjon i en borestreng (2) som har en turbinrotor (10) som kan drives av et strømningsmedium, og en bypassinnretning med en første bypasskanal eller forbiløpskanal som omgår turbinrotoren (10). For forandring av volumstrømmen gjennom bypasskanalen er det anordnet en ventil (28) og en styringsinnretning med et driftselement (24) drevet av strømningsmediet, som ventilen (28) etter ønske kan beveges med mellom en første og en andre stilling. Driftselementet (24) danner en strømningsmotstand i strømningsveien for strømningsmediet som ligger nedstrøms turbinrotoren (10) og nedstrøms ventilen (28), og hviler i strømningsretningen mot en fjær (26).
