Av fig. 1 och la framgar att en fluidumdriven anordning 10 enligt den foreliggande uppfinningen bestar av tre lameller eller tunna skivor 12, 14 och 16. Lamellen 14 är belagen mellan lamellerna 12 och 16 och är genom lampliga model tatande forbunden med de sistnamnda, exempelvis genom anva.ndning av hopdragningsskruvar eller klister (icke vi-sat). Lamellerna 12, 14 och 16 kunna besta av melon, plast eller annat lampligt material. Har ha lamellerna i belysande syfte visats besta av klart plastmaterial. From Figs. 1 and 1a it can be seen that a fluid-driven device 10 according to the present invention consists of three lamellae or thin discs 12, 14 and 16. The lamellae 14 are coated between the lamellae 12 and 16 and are connected by suitable models to the latter, e.g. by using tightening screws or glue (not shown). The slats 12, 14 and 16 can consist of melon, plastic or other suitable material. Has the slats for illustrative purposes been shown to consist of clear plastic material.

Lamellen 14 har en utskuren sektion, som erhallits genom utklippning eller stansning eller pa liknande salt. Hela den utskurna sektionen liar beteeknats som konfigurationen 18, och denna konfiguration 18 innefattar ett fluiduminlopp 20, ett fluidumutlopp 22 och en styrkammare 24. Fluiduminloppet 20 bildar en fortrangd tillforselOppning 26, som star i Virbindelse med utloppet 22 och med styrkaramaren 24. Nar dot hdr talas om en »oppningD, avses en dylik med parallella, konvergerande eller divergerande vaggar eller av nagon annan konventionell form. Inloppet 20 star i forbindelse med en urborrning 28 i lamellen 16. Fluidumutloppets 22 utgangsande kan kommunicera med skilda styr- eller utnyttjningsanordningar (icke visade) far att utf8ra tinskade arbetsfunktioner. 2— — Urborrningen 28 kan vara forsedd med invandiga gangor for att mottaga ett Nit. 30, som har utvandiga gangor. Den ande av rOret 30 som stracker sig ut fran lamellen 16 star i fOrbindelse med en tryckfluidumkalla 32. Det under tryck staende fluidet kan -agoras a-v en. gas eller luft, eller av vatten eller nagon annan vatska. En regleringsanordning for .fluidumstromningen, exempelvis en ventil 34, Wan anvandas i saraband med fluidumkallan 2 far att astadkomma ett konstant fluidumnode vid ett linskat tryck. Dylika regleringsanordningar aro av konventionell konstruktion. The lamella 14 has a cut-out section, which is obtained by cutting or punching or on similar salt. The entire cut-out section is referred to as the configuration 18, and this configuration 18 includes a fluid inlet 20, a fluid outlet 22 and a control chamber 24. The fluid inlet 20 forms a constricted supply opening 26 which communicates with the outlet 22 and with the control chamber 24. When refers to an »openingD, means one with parallel, converging or diverging rocks or of some other conventional form. The inlet 20 is connected to a bore 28 in the lamella 16. The output end of the fluid outlet 22 can communicate with different control or utilization devices (not shown) to perform thinned work functions. 2— - The bore 28 may be provided with internal passages to receive a rivet. 30, which has external passages. The spirit of the tube 30 extending from the lamella 16 communicates with a pressurized fluid source 32. The pressurized fluid can be stored a-v a. gas or air, or of water or any other liquid. A control device for the fluid flow, for example a valve 34, which is used in conjunction with the fluid source 2, provides a constant fluid node at a linear pressure. Such control devices are of conventional construction.

Styrkammaren 24 innehaller en kolv 36 med plan form. Kolven är forsedd med en slang 38, medelst vilken kolven. kan forflyttas till skilda ldgen inuti kammaren for att harigenom fastlagga kammarens momentana volym. The control chamber 24 contains a piston 36 with a flat shape. The piston is provided with a hose 38, by means of which the piston. can be moved to different layers inside the chamber to thereby determine the instantaneous volume of the chamber.

Fluidum som strommar Iran kallan 32 och gar in i anordningen genom inloppet 20 antages i forklarande syfte att befinna sig pa ett visst tryck Over atmosfartrycket. Nar fluidumstrommen erhaller minskad tvarsektionsarea i oppningen eller mynningen 26, okas fluidets hastighet. Fluidumstrommen med den minskade tvarsektionsarean, som anges genom pilen 40, kallas for anordningens effektstrom. Uppbyggnaden eller konstruktionen av anordningen, dvs. laget av effektstrommen, fir sadant att om icke nagon inre eller yttre kraft verkar pa effektstrommen, kommer denna att gh i langdriktningen fran Oppningen 26 in i utloppet 22 och med ostord riftrelse avga genom det nyssnamnda utloppet. Fluid flowing into Iran cold 32 and entering the device through inlet 20 is assumed for explanatory purposes to be at a certain pressure above atmospheric pressure. As the fluid flow receives reduced cross-sectional area in the opening or orifice 26, the velocity of the fluid increases. The fluid flow with the reduced cross-sectional area, indicated by the arrow 40, is called the power flow of the device. The construction or construction of the device, ie. the layer of the power drum, so that if no internal or external force acts on the power drum, it will flow in the longitudinal direction from the opening 26 into the outlet 22 and with undisturbed rupture exit through the just mentioned outlet.

Eftersom effektstriimmen gar genom omradet 42, dar utloppet 22 och styrkammaren 24 sta i forbindelse med varandra, kommer styrkammaren 24 att delvis evakueras. Den pumpverkan som sker Mom omradet 42 katlas i allmanhet for ejektor- eller straIpumpverkan. Sasom resultat av denna pumpverkan uppstar en tryckskillnad mellan den sida av effektstrommen som vetter mot styrkammaren och motsatt sida av effektstrOmmen Om denna tryckskillnad har tillracklig storlek, kommer effektstrommen att i sin helhet eller -till en del ledas in i styrkammaren 24. Harigenom kommer trycket i styrkammaren att stiga nfistan ogonblickligen. Nar trycket i kammaren 24 nar en niva som overstiger det tryck som astadkommes av effektstrommen, kommer effektstrommen att tvingas att lamna styrkammaren 24 och atervanda till den ursprungliga utgangsbanan genom utloppet 22. As the power stream passes through the area 42, where the outlet 22 and the control chamber 24 are in communication with each other, the control chamber 24 will be partially evacuated. The pumping action that takes place in the area 42 is generally rated for ejector or jet pumping action. As a result of this pumping action, a pressure difference arises between the side of the power drum facing the control chamber and the opposite side of the power stream. the control chamber to rise nfistan instantly. When the pressure in the chamber 24 reaches a level exceeding the pressure created by the power drum, the power drum will be forced to leave the control chamber 24 and return to the original outlet path through the outlet 22.

Effektstrommen kan anses representera en fluidumutgangspuls. Varaktigheten eller langden av denna puls ãr lika med tiden f Or ostort fluidumflode, dvs. den tid under vilken effektstrommen ãr riktad mot utloppet 22. Pulsen slutar nar effektstrommen avbrytes, dvs. nar -effektstrommen riktas in i styrkammaren. The power drum can be considered to represent a fluid output pulse. The duration or length of this pulse is equal to the time of undisturbed fluid flow, i.e. the time during which the power current is directed towards the outlet 22. The pulse stops when the power current is interrupted, ie. when the power drum is directed into the control chamber.

A-v den foregaende beskrivningen Or det tyd ligt att effektstrommen fortsatter kings den rata utgangsbanan sa lange som det vakuum som alstras inuti styrkammaren 24 är otillrdckligt for att astadkomma »omkastninp eller »omkoppling» av effektstrommen, dvs. bringa den att avbojas In i styrkammaren. Det Or tydligt att ju mindre volym som kammaren 24 har desto snalabare kommer den vakuumniva att uppnis vid vilken omkopplingen sker. Med andra ord ju mindre volymen av styrkammaren Or desto kortare komma utgangspulserna att bli. I motsvarighet hartill kommer frekvensen av de alstrade pulserna att bli desto h8gre ju kortare pulserna Oro. Omvant kommer frekvensen av de alstrade pulserna att bli desto lagre ju stone volym styrkammaren 24 har. From the foregoing description It is clear that the power drum continues the straight output path as long as the vacuum generated inside the control chamber 24 is insufficient to effect "reversal" or "switching" of the power drum, i.e. bring it to be deflected Into the control chamber. It is clear that the smaller the volume of the chamber 24, the more efficient the vacuum level at which the switching takes place will be. In other words, the smaller the volume of the control chamber Or, the shorter the output pulses will be. Correspondingly, the frequency of the generated pulses will be the higher the shorter the pulses Oro. Conversely, the frequency of the stone volume of the control chamber 24 will be lower the frequency of the generated pulses.

Styrkammarens 24 volym bestammes genom laget av kolven 36 inuti kammaren. Ju djupare kolven Or belagen in i kammaren des-to mindre kommer kammarens volym att ra, och en mindre kammare resulterar i en hogre frekvens av de alstrade pulserna. Det Or tydligt att pa detta satt kan en gradvis frekvensandring inom ett stort omrade ske genom forflyttning av kolven. The volume of the control chamber 24 is determined by the layer of the piston 36 inside the chamber. The deeper the piston Or coated into the chamber, the smaller the volume of the chamber will increase, and a smaller chamber results in a higher frequency of the generated pulses. It is clear that in this way a gradual change of frequency within a large area can take place by moving the piston.

Frekvensregleringen av utgangspulserna medelst styrkammaren 24 behover icke nodvandigtvis best& i en styrning eller reglering av kammarens volym. En alternativ utfOringsform kan inbegripa en lika verksam reglering genom en andring av trycket inuti kammaren 24 under det att kammarens volym Mlles konstant. En dylik tryekreglering kan exempelvis forverkligas genom en glodtrad. En dylik glodtrad kan vara belagen inuti styrkammaren on matas med strain for att &tadkomma varme. Det varme som framkallas genom glodtraden kommer att Oka temperaturen och trycket inuti kammaren 24. Den tryckandring som paverkar effektstiriimmen medfOr att den sistnamnda lamnar kammaren redan beskrivet satt. Den varmemangd som glodtraden utvecklar kommer att be-stamina den tid som erfordras far att bygga upp trycket inuti kammaren till den niva. ddr omkoppling sker av effektstrommen. The frequency control of the output pulses by means of the control chamber 24 does not necessarily have to consist of a control or regulation of the volume of the chamber. An alternative embodiment may involve an equally effective control by changing the pressure inside the chamber 24 while keeping the volume of the chamber constant. Such a pressure control can, for example, be realized by a glow line. Such a filament can be coated inside the control chamber and fed with strain to obtain heat. The heat generated by the filament will increase the temperature and pressure inside the chamber 24. The change in pressure which affects the power flow means that the latter leaves the chamber already described. The heat mantle that the filament develops will determine the time required to build up the pressure inside the chamber to that level. ddr switching is done by the power stream.

Denna anordning mojliggor att astadkomma ett hjalpmontent for omkopplingen av effektstriimmen. 40 in i styrkammaren 24. Fig. 2 schematically shows a modification of the device shown in Fig. 1. Equal details have thereby received the same designations as before. The devices of Figs. 1 and 2 are identical except for the device of Fig. 2 here an opening 44 into the guide area 42. The purpose of the opening 44 is to provide an auxiliary pressure on one side of the power drum 40 to assist in deflecting the power flow into the control chamber 24. The aperture 44 can be used in various ways to influence or control the frequency of the outgoing pulses. The opening 44 can communicate with the atmosphere or with the flag of another suitable pressure cold, depending on the structure of the system and the result desired. Fig. 3 shows another embodiment of the present invention. The same parts have also been given the same designations as before in Fig. 1.
