s =:7a1o269~e Z 40 Figur 3 visar hur friktionen mellan vätskemassan l ooh dess stationära eller medroterande hölje 7 kan minskas genom att frik- tionsminskande medier av kända slag tillföres. I det visade exemplet tillföres exempelvis luft eller gas 8 i bubbelform. Vid andra tillämpningar kan polymertillsatser etc användas. s =: 7a1o269 ~ e Z 40 Figure 3 shows how the friction between the liquid mass l ooh its stationary or co-rotating housing 7 can be reduced by applying friction-reducing media of known types. In the example shown, for example, air or gas 8 is supplied in bubble form. In other applications, polymer additives etc. can be used.
Figur 4 visar hur gaskammaren 5 ovanför vätskerotorn l medelst koncentriska ringformade mellanväggar 9 uppdelas i periferiella rum lü. I dessa rum l0 kan gastrycket regleras individuellt med eller utan gasmatningsanordningar av olika i och för sig kända typer. De med vätskerotorn l koncentriska mellanväggarna 9 kan näven vara centralt lagrade och rotera med vätskemassan l.Figure 4 shows how the gas chamber 5 above the liquid rotor 1 is divided by means of concentric annular partitions 9 into peripheral spaces lü. In these rooms 10, the gas pressure can be regulated individually with or without gas supply devices of different types known per se. The partitions 9 concentric with the liquid rotor 1, the fist can be centrally mounted and rotate with the liquid mass 1.
I den roterande vätskerotorn l uppstår en torusformad sekun- därströmning ll, såsom visas i figur l. Denna sekundärströmning ll i vätskemassan kan pâverkas medelst ledskenor l2 anordnade kon- centriskt med vätskerotorn l i cylinderytor eller i plan vilka är vinkelräta mot axeln l3, såsom visas i figur 5. Figur 6 visar hur en med vätskemassan l medroterande cylindermantel T4 är anordnad nära ytterhöljet 7. Denna cylindermantel l4 kan vara lagrad i maskinhusets 3 axel l3, såsom visas i figuren 6.In the rotating liquid rotor 1 a toroidal secondary flow l1 occurs, as shown in figure 1. This secondary flow l1 in the liquid mass can be influenced by guide rails l2 arranged concentrically with the liquid rotor l in cylindrical surfaces or in planes which are perpendicular to the axis l3, as shown in figure 5. Figure 6 shows how a cylinder jacket T4 co-rotating with the liquid mass 1 is arranged near the outer casing 7. This cylinder jacket 14 can be mounted in the shaft 13 of the machine housing 3, as shown in figure 6.

Detta sker såsom visas schematiskt i figuren medelst en i vätskemassan l nedsänkt modellhàllare l7 anordnad för kraftmätning och strömningsstudiea med såväl ytskärande modeller l8 som helt i vätskan nedsänkta modeller l9. Modellhållaren l7 är anordnad i ett icke närmare betecknat hus ovanför resp. kammare l0.As shown in Figure 7, the energy content of the liquid mass 1 can be complemented by adding solids enclosed in the liquid and rotating therewith, whereby the position of the solids in the cross section can be kept constant or varied with fastening devices of different known types. As shown in Figure 8, the system according to the invention can also be used for hydro-flow mechanical experiments. This is done as shown schematically in the figure by means of a model holder 17 immersed in the liquid mass 1, arranged for force measurement and flow studies with both surface-cutting models 18 and models 19 completely immersed in the liquid. The model holder 17 is arranged in a housing not further specified above resp. chamber l0.

Sålunda är taket eller locket över vätskerotorn l utformat med transparenta sol- paneler 20 varvid värmekroppar 2l kan vara anordnade i eller i närheten av vätskeytan. i ' i Figur l0 visar hur propulsorerna 2 är roterbart lagrade runt den med vätskerotorn l gemensamma axeln l3 och vid sin ytterperiferi är försedda med kugghjul som ingår i ett periferiellt växelsystem l6 av planettyp och på detta sätt bringas att rotera i samma eller 40 3 7810269-6 motsatt riktning som vätskemassan eller vätskerotorn l.Figure 9 shows an energy storage system supplemented with energy input in the form of heat from solar energy. Thus, the roof or lid over the liquid rotor 1 is formed with transparent solar panels 20, whereby heating bodies 21 may be arranged in or near the liquid surface. Figure 10 shows how the propulsors 2 are rotatably mounted around the axis l3 common to the liquid rotor 1 and at their outer periphery are provided with gears which are part of a planetary peripheral gear system 16 and are thus caused to rotate in the same or 40 3 7810269 -6 opposite direction as the liquid mass or liquid rotor l.

Figure 11 shows the housing 7 of the energy storage system placed in the ground or in a water surface and the engine housing 3 centrally in the housing 7. .
Figur l2 visar hur æn koncentriskt med vätskerotorn l anord- nade vertikalaxelturbinen 22 är utformad med reglerbara ledskenor 23 eller andra kända anordningar för överföring av vindenergin till vätskerotorn l.Figure 12 shows how a vertical shaft turbine 22 arranged concentrically with the liquid rotor 1 is formed with adjustable guide rails 23 or other known devices for transmitting the wind energy to the liquid rotor 1.
Figur l3 visar en horisontalaxlad vindturbin 24 på ett kon- ventionellt torn 25. Vindturbinen 24 är försedd med en hydropump- anläggning 26 på turbinaxeln och medelst denna anläggning överföres fluidumenergin via ledningar 27 till vätskemassan l exempelvis med propulsorer 2 i form av ejectorenergimatare.Figure 13 shows a horizontal axis wind turbine 24 on a conventional tower 25. The wind turbine 24 is provided with a hydropump plant 26 on the turbine shaft and by means of this plant the fluid energy is transmitted via lines 27 to the liquid mass 1, for example with propulsors 2 in the form of ejector energy feeders.
Figur l4 visar hur vindenergien utnyttjas för att medelst en på känt sätt anordnad krans av ledskenor 28 alstra en inuti kran- sen anordnad stabiliserad cyklon 29. Från denna cyklon överföres energin till vätskemassan l via en koncentriskt med vätskemassan lagrad överföringsrotor 31 som på vindsidan har reglerbara blad och på vätskesidan har en i vätskemassan anordnad sats regler- bara blad 32.Figure 14 shows how the wind energy is used to produce a stabilized cyclone 29 arranged inside the ring by means of a ring of guide rails 28 arranged in a known manner. From this cyclone the energy is transferred to the liquid mass 1 via a transfer rotor 31 concentrically stored with the liquid mass. leaves and on the liquid side a set 32 arranged in the liquid mass has adjustable leaves 32.
Figur l5 visar hur de koncentriskt ringformade mellanväggarna 9 är utformade som eller utrustade med värmeväxlare 33 för upp- tagande av värme från systemet, speciellt friktionsvärme. Till värmeväxlarna 33 är anslutna ledningar 34, 35 för till- resp. bortförsel av värmeväxlingsfluidum.Figure 15 shows how the concentrically annular partitions 9 are designed as or equipped with heat exchangers 33 for absorbing heat from the system, especially frictional heat. To the heat exchangers 33 are connected lines 34, 35 for supply resp. removal of heat exchange fluid.
Figur lö visar hur tryckkamrarna 10 kan vara utrustade med en wtappningsledning 36 med ventil 37 för reglering av trycket i rummet. Ventilen är kopplad till en reglerkrets här illustrerad med en reglerbox 38 och i reglerkretsen ingår även en nivákännare 39 som avkänner vätskenivàn i tryckkammaren ifråga. Vid förang- ning i tryckkammaren och därav följande tryckökning som tenderar att förändra vätskeniván i kammaren l0 träder reglerkretsen i funktion och eventuell tryckavlastning sker till dess att vätske- nivån nått önskat läge.Figure 1u shows how the pressure chambers 10 can be equipped with a drain line 36 with valve 37 for regulating the pressure in the room. The valve is connected to a control circuit here illustrated with a control box 38 and the control circuit also includes a level sensor 39 which senses the liquid level in the pressure chamber in question. Upon evaporation in the pressure chamber and the consequent pressure increase which tends to change the liquid level in the chamber 10, the control circuit comes into operation and any pressure relief takes place until the liquid level has reached the desired position.

Figure 17 shows that the concentric partitions 40 are formed with heat exchange surfaces and an inner separate fluid 43 as well as the outer wall 41 and the heating fluid 43 flows between the walls 40 and 41 in various known ways for heat exchange optimization, and is controlled by valves 42.
