Claims (9)

1. Indretning til konvertering af kinetisk energi af strømmende vand til kinetisk energi af en roterbar rotoraksel (4), hvor indretningen er indrettet til at være effektiv i en første strømningsretning og i en anden strømningsretning, som er i det væsentlige modsat den første, hvor indretningen omfatter to rotorblade (7, 8), som hver er forbundet med en bladaksel (6), der er koblet til rotorakslen (4) til overførsel af et moment i forhold til rotorakslen, idet bladakslen (6) strækker sig vinkelret på rotorakslen (4), kendetegnet ved, at bladene (7, 8) hver især er stift forbundet med den samme bladaksel (6), at bladakslen er monteret til rotation omkring sin egen akse i forhold til rotorakslen (4), og at rotorbladene (7, 8) hver har et asymmetrisk tværsnit.
2. Indretning ifølge krav 1, kendetegnet ved, at bladakslen (6) er anbragt i en afstand fra rotorbladprofilets momentpunkt.
3. Indretning ifølge krav 1, kendetegnet ved, at bladakslen (6) strækker sig gennem rotorbladprofilets momentpunkt.
4. Indretning ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at indretningen omfatter reverseringsmidler til at rotere rotorbladene (7, 8) mellem en første og en anden position.
5. Indretning ifølge krav 4, kendetegnet ved, at rotorakslen (4) antager en hul form, og at reverseringsmidlerne omfatter en reverseringsaksel, som strækker sig gennem rotorakslen (4), og som er koblet til bladakslen (6) ved hjælp af en tandhjulstransmission, samt drivorganer til at drive reverseringsakslen i rotation.
6. Indretning ifølge krav 5, kendetegnet ved, at reverseringsmidleme omfatter en asymmetrisk konfiguration af rotorakslen (4) og rotorbladene (7, 8).
7. Indretning ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at indretningen omfatter stopmidler til at stoppe rotorbladene (7, 8) i den første og den anden position, og at stopmidleme omfatter et første stop og et andet stop (13, 14) til at afgrænse rotorbladenes (7, 8) bevægelse mellem den første position og den anden position via den samme vej.
8. Indretning til konvertering af kinetisk energi af strømmende vand til elektrisk energi, kendetegnet ved en indretning ifølge et hvilket som helst af de foregående krav, hvis rotoraksel (4) er koblet til en elektrisk generator.
9. Fremgangsmåde til konvertering af kinetisk energi af strømmende vand til kinetisk energi af en roterbar rotoraksel, hvor vandet kan strømme skiftevis i en første strømningsretning og i en anden strømningsretning, som er i det væsentlige modsat den første, og hvor fremgangsmåden anvender en indretning ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at når strømningsretningen ændres, ændrer rotorbladene (7, 8) position, og at ændringen i bladenes (7, 8) position forårsages af vending af strømningsretningen eller af reverseringsmidler.
