Claims (6)
1. Francisturbin, francispumpturbin eller francispump med ett löphjul med stor diameter, varvid löphjulet (2) i omrädet av sin omkrets medelst radiallagring lagrats i fundamentet (7), och radial-lagringen (4) uppvisar med en ringyta hos löphjulet (2) samverkande lagerskor (5), kännetecknad därav, att lagerskorna medelst en hydraulisk ställmotor (6) är lagrade i fundamentet (7) varvid ställmotorn (6) är anordnad för radiellt inställande av lagerskon (5) relativt löphjulet (2).
2. Francisturbin, francispumputurbin eller francispump enligt patentkravet 1, kännetecknad därav, att ätminstone tre i det närmaste jämnt över ytterkransens omkrets fördelade lagerskor (5) är utbildade som centreringslager (5^), vid vilka ställmotorn 1 (6 ) är försedd med en anordning (8) som ökar trycket i ställmotorn (6 ) vid dennas sammantryckning och omvänt, sk att lagerskons (5 ) stödkraft ökar vid ställmotorns (6^) sammantryckning.
3. Francisturbin, francispumpturbin eller francispump enligt patentkravet 1, kännetecknad därav, att ätminstone tre i 2 det närmaste jämnt över ytterkransens omkrets fördelade lagerskor (5 ) är utbildade som hängdämpningslager, vid vilka ställmotorn (6^) är försedd med en anordning som vid längsamma rörelser av ställmotorn (6 ) bibehäller trycket konstant i ställmotorn, men vid en plötslig 2 sammantryckning av ställmotorn (6 ) höjer trycket i denna sä att lagerskons (5 ) stödkraft förblir lika stor vid längsamma rörelser av lagerskon men ökar vid en snabb belastning av lagerskon.
4. Francisturbin, francispumpturbin eller francispump enligt patentkravet 1, med ett löphjul med lutande eller horisontell axel, O kännetecknad därav, att ätminstone en lagersko (5 ) är 3 - utbildad som hänglager, vid vilket ställmotorn (6 ) är försedd med en trycket i ställmotorn konstanth&llande anordning, sk att lagerskons 3 (5 ) stödkraft är lika stor vid alla radiella lägen av lagerskon.
5. Francisturbin, francispumpturbin eller francispump enligt nägot av patentkraven 1-4, kännetecknad därav, att lagerskorna (5) är svängbart utbildade relativt fundamentet (7).
6. Francisturbin, francispumpturbin eller francispump enligt patentkravet 5, kännetecknad därav, att ställmotorns (6) kolv och cylinder är svängbart anordnade i varandra.
