Baggrund for opfindelsenBACKGROUND OF THE INVENTION

Området for opfindelsenField of the Invention

Denne opfindelse angår generelt indretninger til at blive anvendt i bilmotorer 5 og andre små motorer, hvor indretningerne fjerner partikler og flygtige bestanddele fra den olie, som bliver anvendt i sådanne motorer.This invention relates generally to devices for use in automobile engines 5 and other small engines, the devices removing particles and volatile components from the oil used in such engines.

Beskrivelse af den kendte teknik I teorien skulle olie, som bliver anvendt til at smøre maskindele, vare evigt, 10 fordi olien i sig selv aldrig bliver nedbrudt. Der er imidlertid to forureningskilder, som ødelægger effektiviteten af olie som et smøremiddel: Slibende partikulært materiale og flygtige bestanddele som fugt eller uforbrændt brændstof. Derfor har opfindere udviklet filterindretning til at fjerne partikulært materiale og fordamperindretninger til at fjerne fugt og andet flygtigt, som nedbryder effektiviteten af olien.Description of the Prior Art In theory, oil used to lubricate machine parts should last forever, 10 because the oil itself never degrades. However, there are two sources of pollution that destroy the effectiveness of oil as a lubricant: abrasive particulate matter and volatile constituents such as moisture or unburned fuel. Therefore, inventors have developed filtering devices for removing particulate matter and evaporator devices for removing moisture and other volatiles which degrade the efficiency of the oil.

15 Der er ligeledes blevet udviklet indretninger, som kombinerer disse to funktio ner. F.eks. viser US patent nr. 4.189.351, Engel en kombineret filter- og fordamperenhed. Olie, som skal blive filtreret for at fjerne partikulært materiale fra det, og som skal blive opvarmet i et fordamperkammer for at fjerne flygtige bestanddele fra den, bliver først indført i en beholder, som er fyldt med filtermateriale. Efter at have strømmet 20 gennem filtermaterialet bliver olien indført i et fordamperkammer, hvor den bliver spredt ud i et tyndt lag og opvarmet for at forstærke dens fordampning. En udstrømningsåbning tillader, at fordampede flygtige bestanddele undslipper til atmosfæren.15 Devices have also been developed which combine these two functions. Eg. U.S. Patent No. 4,189,351, Engel discloses a combined filter and evaporator unit. Oil, which must be filtered to remove particulate matter from it, and which must be heated in an evaporator chamber to remove volatiles from it, is first introduced into a filter-filled container. After flowing 20 through the filter material, the oil is introduced into an evaporator chamber where it is spread into a thin layer and heated to enhance its evaporation. An outflow orifice allows evaporated volatiles to escape to the atmosphere.

Der er to primære ulemper ved den ovenfor beskrevne indretning. Fordampningen bliver udført ineffektivt, fordi det varmeelement, som skal tilføre varme til for-25 dampningskammeret, er placeret i lukkeindretningen til indretningen, og således skal fordampningsvarmen blive tilført ved strålevarme, og indretningen er for stor til at passe under en bils motorhjelm.There are two primary drawbacks to the device described above. The evaporation is performed inefficiently because the heating element which is supposed to supply heat to the evaporation chamber is located in the closing device of the device and thus the evaporation heat must be supplied by radiant heat and the device is too large to fit under the car's bonnet.

Problemet med den ineffektive opvarmning blev løst ved hjælp af en indretning, som bliver vist i US patent nr. 5.198,104, Menyhert. I denne indretning bliver op-30 varmningselementet placeret i den fordamperplade, hvor der er behov for varmen, og det fyldige, varmeudstrålende låg ifølge Engel’s indretning bliver undgået. Indretningen er imidlertid ligeledes for stor til at passe under en bils motorhjelm. Endvidere er udformningen af begge tidligere indretninger sådan, at en udskiftning af filtermateriale er noget vanskelig. I særdeleshed er filtermedierne i begge indretninger placeret i en be- 2 DK 173823 B1 holder, som bliver fastgjort til fordamperpladen. Så der bliver krævet i det mindste en delvis adskillelse af sådanne indretninger, når filtermediet bliver udskiftet.The problem of inefficient heating was solved by means of a device shown in US Patent No. 5,198,104, Menyhert. In this device, the heating element is placed in the evaporator plate where the heat is needed and the full, heat-radiating lid of Engel's device is avoided. However, the device is also too large to fit under the bonnet of a car. Furthermore, the design of both prior devices is such that a replacement of filter material is somewhat difficult. In particular, the filter media in both devices is located in a container which is attached to the evaporator plate. So, at least a partial separation of such devices is required when the filter medium is replaced.

Dette sidste problem er løst med den indretning, som er vist i US-5,843,284. I denne indretning påskrues filteret blot på bunddelen af fordamperenheden. Imidlertid 5 omfatter fordamperenheden en topdel og en bunddel, som er indbyrdes forbundet og forseglet mod væskelaekage ved hjælp af en pakning imellem de to dele. Varmeelementet for frembringelse af energi til fordampning af flygtige forurenende stoffer i væsken er monteret i topdelen, nedefra, og følgelig kræver udskiftning af varmeelementet en adskillelse af fordamperenheden. En anden ulempe ved denne tidligere kendte 10 konstruktion er mulighederne for lækage. Pakningen skal tætne over en stor overflade, over hvilken store temperaturforskelle kan forekomme, som potentielt kan forårsage skævridning af disse overflader.This last problem is solved with the device shown in US-5,843,284. In this device, the filter is simply screwed onto the bottom portion of the evaporator unit. However, the evaporator unit comprises a top part and a bottom part which are interconnected and sealed against liquid leakage by means of a gasket between the two parts. The heating element for generating energy to evaporate volatile pollutants in the liquid is mounted in the top part from below, and consequently the replacement of the heating element requires a separation of the evaporator unit. Another disadvantage of this prior art construction is the potential for leakage. The gasket must seal over a large surface, over which large temperature differences may occur, potentially causing distortion of these surfaces.

Baseret på denne kendte teknik er det formålet med nærværende opfindelse, at tilvejebringe en forbedret konstruktion med færrre muligheder for lækage og en me-15 re passende samling af konstruktionens dele, og dette formål opnås med en konstruktion som angivet i krav 1.Based on this prior art, the object of the present invention is to provide an improved structure with fewer opportunities for leakage and a more appropriate assembly of the parts of the structure, and this object is achieved with a structure as claimed in claim 1.

Resume af opfindelsenSummary of the Invention

Det mangeårige men ikke desto mindre uopfyldte behov for en kombineret 20 filter- og fordamperindretning ved en lille størrelse, som har en indretning, som letter en udskiftning af filtermaterialet, bliver nu opfyldt ved hjælp af en konstruktion, som omfatter et filterhus, som er skruet i indgreb udvendigt, og som blot er omkring 41A inch i diameter.The long-standing but nevertheless unmet need for a small size combined filter and evaporator device having a device which facilitates replacement of the filter material is now met by a construction comprising a filter housing which is screwed on the outside, which is only about 41A in diameter.

Udformningen af det nye apparatur tvinger olie, som kommer ind i enheden, til 25 først at flyde ind i filterhuset og derefter ind i fordamperkammeret af enheden. Et tilpasningsstykke forbinder filterhuset til fordamperenheden. Filterhuset har et hult, cylindrisk hovedlegeme, som holder filtermaterialet, og har en reces, som er udformet i en øvre væg af det, som har gevind til et skruet indgreb med tilpasningsstykket. Så når filtermaterialet bliver ude af stand til at fjerne yderligere partikulære forureninger, bliver 30 filterhuset simpelthen skruet fra tilpasningstykket, og et nyt filter bliver installeret; der bliver ikke krævet nogen adskillelse af indretningen.The design of the new apparatus forces oil entering the unit to first flow into the filter housing and then into the evaporator chamber of the unit. An adapter piece connects the filter housing to the evaporator unit. The filter housing has a hollow cylindrical main body which holds the filter material and has a recess formed in an upper wall of it which is threaded for a screwed engagement with the adapter. Then, when the filter material becomes unable to remove further particulate contaminants, the filter housing is simply unscrewed from the fitting and a new filter is installed; no separation of the device is required.

En lille måleråbning er udformet i tilpasningsstykket for at gøre det muligt for olie, som kommer ud af filterhuset, at komme ind i fordamperenheden. Ifølge en fore-trukken udførelsesform bliver diameteren af åbningen valgt sådan, at olie kan strømme DK 173823 B1 3 igennem den med omkring 5 eller 6 gallons pr. time, selv om andre strømningshastigheder selvfølgelig ligger inden for området for denne opfindelse.A small gauge opening is provided in the adapter piece to allow oil coming out of the filter housing to enter the evaporator unit. According to a preferred embodiment, the diameter of the aperture is selected such that oil can flow through it at about 5 or 6 gallons per meter. of course, although other flow rates are, of course, within the scope of this invention.

Når olien strømmer gennem måleåbningen, bliver den indført i fordamperkammeret gennem mange passager, som er udformet som skorstene, som det bliver 5 vist i begge de ovenfor nævnte patenter, og derefter spredt tyndt ud over bunden af fordamperkammeret; nævnte kammer bliver direkte opvarmet i overensstemmelse med fremlæggelserne i det ovenfor nævnte patent, som er udstedt til Menyhert. Låget til nærværende apparatur adskiller sig imidlertid fra låget til den indretning, som bliver vist i nævnte patent, derved, at det tidligere låg har en åbning, som er udformet i det, til 10 at skaffe plads til en central stolpe af fordamperpladen, som modtager varmeelementet. Nærværende udformning omfatter et uperforeret låg for at reducere et varmetab fra fordamperkammeret, og låget kommer ikke i indgreb med nævnte centrale stolpe.As the oil flows through the metering aperture, it is introduced into the evaporator chamber through many passageways, which are shaped like chimneys, as shown in both of the above patents, and then spread thinly across the bottom of the evaporator chamber; said chamber is directly heated in accordance with the disclosures in the aforementioned patent issued to Menyhert. However, the lid of this apparatus differs from the lid of the device shown in said patent, in that the former lid has an aperture formed therein to provide space for a central post of the evaporator plate which receives heating element. The present embodiment comprises an unperforated lid to reduce heat loss from the evaporator chamber and the lid does not engage said central post.

Så både konstruktionen af indretningen og dens effektivitet er forbedret.So both the design of the device and its efficiency have improved.

Det skal således blive forstået, at et hovedformål med nærværende opfindel-15 se er at fremme teknikken for typen af kombinerede filter- og fordamperenheder ved at tilvejebringe en indretning med en filterindretning, som let kan blive udskiftet, og en mere effektiv fordamperindretning.Thus, it is to be understood that a principal object of the present invention is to advance the technique of the type of combined filter and evaporator units by providing a device with an easily replaceable filter device and a more efficient evaporator device.

Et andet vigtigt formål er at fremme nævnte teknik ved at tilvejebringe en indretning, som er lille nok til at blive anvendt i bilmotorer, traktormotorer og andre små 20 motorer.Another important object is to advance said technique by providing a device small enough to be used in automobile engines, tractor engines and other small engines.

Disse og andre vigtige formål, kendetegn og fordele ved opfindelsen vil fremgå, som denne beskrivelse skrider frem.These and other important objects, features and advantages of the invention will become apparent as this description progresses.

Opfindelsen omfatter derfor de karakteristiske træk ved konstruktionen, kombination af elementer og anbringelse af dele, som der bliver givet eksempler på i den 25 konstruktion, som vil blive fremført, og området for opfindelsen vil blive angivet i kravene.The invention therefore encompasses the characteristic features of the construction, combination of elements and arrangement of parts, examples of which will be given in the construction which will be set forth and the scope of the invention will be specified in the claims.

Detaljeret beskrivelse af opfindelsenDetailed description of the invention

Idet der nu bliver henvist til fig. 1-3, kan man se, at et eksempel på en udførelsesform af opfindelsen bliver angivet som en helhed ved hjælp af reference nr. 10.Referring now to FIG. 1-3, one can see that an example of an embodiment of the invention is given as a whole by reference no. 10.

Et apparatur 10 til regeneration af væsker omfatter en filterindretning, som 15 generelt bliver angivet med 12 (fig. 2 og 3), samt en fordamperindretning, som generelt bliver angivet med 14. I en foretrukken udførelsesform er både filterindretningen 12 og fordamperindretningen 14 med en cylindrisk udformning og har en fælles diameter, men forskellige former og størrelser af begge af nævnte dele er inden for området af denne opfindelse. Der bliver fjernet faste bestanddele fra den væske, som skal blive 20 regenereret, ved hjælp af filterindretningen 12, og flygtige bestanddele bliver fjernet fra den ved hjælp af fordamperindretningen 14. Man skal indledningsvis bemærke, at filterindretningen 12 let kan blive frigjort fra fordamperindretningen 14, og at der ikke bliver krævet nogen adskillelse af fordamperindretningen 14, når filterindretningen 12 bliver skiftet.An apparatus for regenerating liquids comprises a filter device which is generally indicated by 12 (Figures 2 and 3), and an evaporator device which is generally indicated by 14. In a preferred embodiment, both the filter device 12 and the evaporator device 14 are provided with a cylindrical in shape and having a common diameter, but different shapes and sizes of both of said parts are within the scope of this invention. Solid components are removed from the liquid to be regenerated by the filter device 12 and volatile components are removed from it by the evaporator 14. It should be noted initially that the filter device 12 can be easily released from the evaporator 14. and that no separation of the evaporator device 14 is required when the filter device 12 is changed.

25 Filterindretningen 12 har et hult hovedlegeme 16, et filtreringsmiddel 18, som er placeret i nævnte hule hovedlegeme, flere åbningere 20, som er udformet i en øvre væg 17 af den, og som sammen tilvejebringer filterindløbet, samt en central udløbspassage 22. Væske, som kommer ind i indløbene 20, som det bliver angivet ved hjælp af retningspile 21, skal passere gennem midlet 18, før det kommer Ind i udløbspassa-30 gen 22; filtreringsmidlet bliver valgt sådan, at størrelsen af partikler, som kommer ind i nævnte passage 22, ikke vil være større end 1 Ångstrøm. Åbningerne 23, som er udformet i de cylindriske sidevægge af udløbspassagen 22, tillader den filtrerede olie at komme ind i nævnte passage 22, som det bliver angivet ved hjælp af retningspile 25.The filter device 12 has a hollow main body 16, a filtering means 18 located in said hollow main body, several apertures 20 formed in an upper wall 17 thereof, which together provide the filter inlet, and a central outlet passage 22. Liquid, entering the inlets 20 as indicated by directional arrows 21 must pass through the means 18 before entering the outlet passage 22; the filtering agent is selected such that the size of particles entering said passage 22 will not be greater than 1 Angstrom. The apertures 23 formed in the cylindrical side walls of the outlet passage 22 allow the filtered oil to enter said passage 22 as indicated by directional arrows 25.

Som det bedst bliver vist i fig. 3 og 6, omfatter fordamperindretningen 14 en 35 beholder 24, som har en bundvæg 26 og øvre sidevægge 28, som er anbragt over DK 173823 B1 5 omkredsen af den og er rettet opad fra den til at danne en åben top; den øverste ende af de opadrettede sidevægge bliver angivet ved 30.As best shown in FIG. 3 and 6, the evaporator device 14 comprises a container 24 having a bottom wall 26 and upper side walls 28 disposed over the circumference thereof and directed upwardly from it to form an open top; the upper end of the upward sidewalls is indicated by 30.

Beholderen 24 omfatter yderligere nedre sidevægge 32, som er monteret over omkredsen af bundvæggen 26, og som hænger ned fra den, samt en åben bund. Den 5 nederste ende af de nedadhængende sidevægge bliver angivet med 34.The container 24 further comprises lower side walls 32 which are mounted above the circumference of the bottom wall 26 and which hang down from it, as well as an open bottom. The bottom 5 end of the downward-facing side walls is indicated by 34.

En lukkeindretning 36 lukker den åbne top af nævnte beholder. Skrueelementer, som samlet bliver angivet med 38 (fig. 2), muliggør en let fjernelse og genpåsætning af nævnte lukkeindretning, og et lufthul tilvejebringer den funktion, som bliver udtrykt ved hjælp af dens navn. De øverste ender 30 af de opadrettede sidevægge 28 10 bliver tilspidset som angivet med 39 i fig. 6 til at modtage nævnte skruer 38 såvel som knaster 42, som er udformet i låget 38. Talrige andre indretninger til at fastgøre låget 36, så det kan blive frigjort, til beholderen 24 er inden for området af denne opfindelse.A closure device 36 closes the open top of said container. Screw elements, which together are indicated by 38 (Fig. 2), allow for easy removal and reattachment of said closure device, and an air hole provides the function which is expressed by its name. The upper ends 30 of the upward sidewalls 28 10 are tapered as indicated by 39 in FIG. 6 to receive said screws 38 as well as lugs 42 formed in the lid 38. Numerous other means for securing the lid 36 so that it can be released to the container 24 are within the scope of this invention.

Et fordamperkammer 44 er afgrænset i nævnte beholder, hvor nævnte lukkeindretning 36 fastlægger den øvre grænse af nævnte fordamperbeholder, nævnte 15 bundvæg 26 fastlægger den nedre grænse af det, og nævnte opadrettede sidevægge 24 fastlægger den yderste omkreds af det.An evaporator chamber 44 is defined in said container, said closure device 36 defining the upper bound of said evaporator container, said bottom wall 26 defining the lower boundary thereof, and said upward sidewalls 24 defining the outer circumference thereof.

Et tilpasningsstykke 46, som bliver vist i fig. 1, 3, 7 og 8, forbinder fordamper-indretningen 14 og filterindretningen 12; det omfatter en plan hovedlegemsdel 48 og en rørformet hals 50, som hænger ned fra det. Den rørformede hafs 50 er udformet til 20 at komme i indgreb, så den kan blive frigjort, med en reces 52 (fig. 3), som er udformet i midten af den øvre væg 17 af nævnte filterindretning. I særdeleshed er halsen 50 udvendigt forsynet med gevind, og recessen 52 er forsynet med indvendigt gevind, men enhver passende fastgøringsindretning til hurtig frigørelse kunne blive anvendt til at forbinde halsen 50 af tilpasningsstykket og halsen 52 af filteret. Det skal ligeledes 25 blive bemærket, at filterindretningen 12 ligeledes kunne have en flaskeform, dvs. med et ydre gevind i den opadrettede hals kunne erstatte recessen 52, og mellemstykket 46 kunne have en reces med indre gevind i stedet for halsen 50.An adapter piece 46 shown in FIG. 1, 3, 7 and 8, the evaporator means 14 and the filter device 12 connect; it comprises a flat main body portion 48 and a tubular neck 50 which hangs from it. The tubular housing 50 is configured to engage so that it can be released, with a recess 52 (Fig. 3) formed in the center of the upper wall 17 of said filter device. In particular, the neck 50 is externally threaded and the recess 52 is internally threaded, but any suitable quick release fastener could be used to connect the neck 50 of the adapter and neck 52 of the filter. It should also be noted that the filter device 12 could also have a bottle shape, i.e. with an outer thread in the upward neck could replace the recess 52 and the intermediate piece 46 could have a recess with an internal thread instead of the neck 50.

Et ringformet trin 54 (fig. 6) er udformet i bundvæggen 26, og flere boringer 56, som ligger i en afstand fra hinanden på en periferi og forsynet med indre gevind, er 30 udformet i det. Boringer 57, som er placeret med tilsvarende afstande, er udformet nær omkredskanten af tilpasningsstykkets hovedlegeme 46, og skruer 55 sikrer nævnte tilpasningsstykke til nævnte trin 54, som det bliver vist i fig. 3.An annular step 54 (Fig. 6) is formed in the bottom wall 26, and a plurality of bores 56 spaced apart on a periphery and provided with internal threads 30 are formed therein. Bores 57 located at similar distances are formed near the circumferential edge of the main body 46 of the adapter piece, and screws 55 secure said adapter piece to said step 54 as shown in FIG. Third

En reces 49 (fig. 6) er udformet i den nedre overflade af bundvæggen 26, radialt indefter i forhold tii nævnte ringformede trin. Der bliver således afgrænset et 35 reservoir 58 (fig. 3) mellem beholderens bundvæg 26 og tilpasningsstykkets hovedle- DK 173823 B1 6 gerne 48, når nævnte hovedlegeme bliver fastgjort til det ringformede trin 54. Mere specielt bliver nævnte reservoir udformet, fordi tilpasningsstykkets hovedlegeme 48 er plant og ligger hen over nævnte reces.A recess 49 (Fig. 6) is formed in the lower surface of the bottom wall 26, radially inwardly relative to said annular steps. Thus, a reservoir 58 (Fig. 3) is delineated between the bottom wall 26 of the container and the main body of the adapter piece 48, when said main body is attached to the annular step 54. More specifically, said reservoir is designed because the main body 48 of the adapter piece 48 is formed. is flat and lies above said recess.

En måleboring 59 er udformet i nævnte tilpasningsstykkes hovedlegeme cen-5 trait i det og tilvejebringer en væskeforbindelse mellem filtrets udløbspassage 22 af filterindretningen 12 og reservoiret 58.A measuring bore 59 is formed in the main body of said adapter piece in it and provides a fluid connection between the filter outlet passage 22 of the filter device 12 and the reservoir 58.

Flere åbninger, som under et bliver betegnet med 60, bliver udformet i bundvæggen 26 af beholderen 24. Disse åbninger giver væske i reservoiret 58 adgang ind i fordamperkammeret 44, som det bliver angivet ved hjælp af retningspile 61 i fig. 3.Several apertures, which are designated at one time by 60, are formed in the bottom wall 26 of the container 24. These openings allow fluid in the reservoir 58 to enter the evaporator chamber 44 as indicated by directional arrows 61 in FIG. Third

10 Mere specielt er åbningerne 60 langstrakte, koniske boringer, som er udfor met i opretstående, halvcirkulært udformede skorstenselementer 70, som er placeret diametralt over for hinanden, som det bedst bliver vist i fig. 4. Det skal blive forstået, at åbningerne 60, som er udformet i bundvæggen 26, og boringerne 60, som er udformet 1 nævnte skorstenseiementer, løber sammen med hinanden og er den samme del, 15 fordi nævnte skorstenselementer bliver udformet integreret med nævnte bundvæg.More particularly, the openings 60 are elongated, tapered bores formed in upright, semi-circular chimney elements 70 which are diametrically opposed to one another as best shown in FIG. 4. It is to be understood that the openings 60 formed in the bottom wall 26 and the bores 60 formed in said chimney elements coincide with each other and are the same part 15 because said chimney elements are formed integrally with said bottom wall.

En opadrettet central muffe 76 bliver ligeledes udformet integreret med bundvæggen 26; den har en hul konstruktion og kan glidende optage et varmeelement 78 (fig. 3) i sig. Bemærk, at varmeelementet 78 opvarmer nævnte centrale muffe og bundvæg 26 direkte, samt at elektriske ledninger 80 kommer ind i lukkeindretningen 20 36 gennem en rørformet åbning 82, som er udformet i en sidekant af lukkeindretnin gen. Nævnte ledninger 80 forbinder opvarmningselementet og en ydre elektrisk kraftkilde, som ikke bliver vist. Som det bliver vist i fig. 1 og 2, er den rørformede åbning 82 udformet ved hjælp af et rørformet element, som bliver angivet ved hjælp af det samme referencenummer, hvor nævnte ringformede element 82 er udformet integreret 25 med lukkeindretningen 36. Nævnte ringformede element 82 er udstrakt radialt udefter fra nævnte lukkeindretning i samme plan som dette. Et hylster 81, som rummer ledningerne 80, er forbundet til det rørformede element 82, som det bedst bliver vist i fig.An upwardly central sleeve 76 is also formed integrally with the bottom wall 26; it has a hollow construction and can slidingly absorb a heating element 78 (Fig. 3). Note that the heating element 78 directly heats said central sleeve and bottom wall 26, and that electrical wires 80 enter the closure device 20 36 through a tubular opening 82 formed in a side edge of the closure device. Said wires 80 connect the heating element and an external electric power source which is not shown. As shown in FIG. 1 and 2, the tubular opening 82 is formed by means of a tubular element which is indicated by the same reference number, wherein said annular element 82 is formed integrally with the closing device 36. Said annular element 82 is radially extended outwardly from said closure in the same plane as this. A sleeve 81 which holds the leads 80 is connected to the tubular member 82, as best shown in FIG.

2 og 3.2 and 3.

Indføjningselementer, som ikke bliver vist, kan ligesåvei blive tilvejebragt for 30 at øge overfladearealet af den overflade, over hvilken olien strømmer; de bliver anbragt mellem den centrale muffe 76 og skorstenene 70.Inserting elements which are not shown may also be provided to increase the surface area of the surface over which the oil flows; they are disposed between the central sleeve 76 and the chimneys 70.

Væske, som skal blive regenereret, kommer ind i apparaturet 10 gennem et beholderindløb 90, som bliver udformet i de nedre sidevægge 32 af beholderen 24, som det bedst bliver forstået i forbindelse med fig. 3. En tvangsindretning til at tvinge 35 væske, som skal blive regenereret, til at strømme fra nævnte indløb 90 ind i det hule DK 173823 B1 7 indre af filterindretningen 12, gennem filtreringsmidlet 18, som er indeholdt i det, gennem måleboringen 59 via filtreringsmidlets udløb 22 ind i reservoiret 28 og ind i fordamperkammeret 44 via nævnte flere boringer 60, som er udformet i bundvæggen 26, bliver tilvejebragt ved hjælp af de respektive konstruktioner af og midler til fastgøring af 5 nævnte filterindretning 12 og nævnte beholder 24.Liquid to be regenerated enters the apparatus 10 through a container inlet 90 which is formed in the lower side walls 32 of the container 24, as is best understood in connection with FIG. A forced device forcing 35 liquid to be regenerated to flow from said inlet 90 into the hollow interior of filter device 12, through the filtering means 18 contained therein, through the measurement bore 59 via the filtering means. Outlet 22 into reservoir 28 and into evaporator chamber 44 via said multiple bores 60 formed in bottom wall 26 is provided by the respective constructions and means for attaching said filter device 12 and said container 24.

Mere specielt vil den øvre væg 17 af filterindretningens hovedlegeme 16 støde helt op til de nederste ender 34 af de nedhængende sidevægge 32, når nævnte filterindretning kommer i indgreb med tilpasningsstykket 46, og en pakningsindretning 94 (fig. 3) bliver placeret mellem nævnte øvre væg 17 og nævnte nederste ende 34 af 10 nævnte nedhængende sidevægge 32. Dette arrangement af dele skaber et lukket rum 96 sådan, at når en væske under et tryk bliver indført i indløbsindretningen 90, er den eneste vej, som er åben for passage af nævnte indkommende væske, som det bliver angivet ved hjælp af retningspile, som bliver angivet med 21, dvs. væsken skal komme ind i filterindløbene 20, strømme gennem filtermaterialet 18 og komme ud af nævnte 15 filter gennem udløbspassagen 22.More particularly, the upper wall 17 of the main body 16 of the filter device will abut all the way to the lower ends 34 of the hanging side walls 32 when said filter device engages the adapter piece 46 and a gasket 94 (Fig. 3) is placed between said upper wall 17 and said bottom end 34 of 10 said hanging sidewalls 32. This arrangement of parts creates a closed space 96 such that when a fluid is pressurized into the inlet device 90, the only path open for passage of said incoming fluid as indicated by directional arrows indicated by 21, i.e. the liquid must enter the filter inlets 20, flow through the filter material 18 and come out of said 15 filter through the outlet passage 22.

Den filtrerede væske strømmer derefter gennem måleåbningen 59 ind i reservoiret 28 og på bundvæggen 26 er fordamperindretningen gennem boringerne 60, som er udformet i skorstenene 70, som det er nævnt før. Efter de flygtige bestanddele er blevet udluftet gennem lufthullet 40, vil den filtrerede og fordampede dvs. regenerere-20 de olie forlade fordampningskammeret 44 gennem en åbning 98, og et rør 99 bringer nævnte regenererede olie tilbage til motoren. En trykforskel, som bliver skabt ved hjælp af motorens drift, sikrer, at olien altid vil strømme ind i enheden 10 ved indløbet 90, som er under bundvæggen 26, og forlade enheden gennem nævnte udløbsåbning 98, som er over nævnte bundvæg.The filtered liquid then flows through the metering aperture 59 into the reservoir 28 and on the bottom wall 26 is the evaporator device through the bores 60 formed in the chimneys 70, as previously mentioned. After the volatiles have been vented through the air hole 40, the filtered and evaporated, i.e. the regenerated oil exits the evaporator chamber 44 through an opening 98 and a tube 99 returns said regenerated oil to the engine. A pressure difference created by the operation of the engine ensures that the oil will always flow into the unit 10 at the inlet 90 which is below the bottom wall 26 and leave the unit through said outlet opening 98 which is above said bottom wall.

25 Et brugt filter 12 kan tydeligvis let blive skilt fra halsen 50 af tilpasningsstykket 46, og et nyt filter kan ligeså let blive installeret. Ingen dele af beholderen 24 behøver at blive skilt ad, når filteret bliver skiftet.Obviously, a used filter 12 can easily be separated from the neck 50 by the adapter piece 46, and a new filter can equally easily be installed. No parts of the container 24 need to be separated when the filter is changed.

Samlingen 10 kan blive monteret til eller i nærheden af en motor på mange forskellige måder. Fig. 2 viser et beslag 100 i form af en plan flade, som bliver monte-30 ret på en væg i nærheden af en motor ved hjælp af bolte 102. Der er udformet en stiv arm integreret med nævnte plane flade 100, som springer radialt ud fra den, og som er i indgreb med modsatte ender af et plant, cirkulært bånd 106, som omkredser de øvre sidevægge 28; der er tilvejebragt almindelige indretninger, som ikke bliver vist, for at spænde nævnte bånd omkring nævnte sidevægge 28. En ringformet reces 108 til at DK 173823 B1 8 optage et bånd bliver fortrinsvis udformet i nævnte sidevægge for at forhindre, at båndet glider.The assembly 10 can be mounted to or near an engine in many different ways. FIG. 2 shows a bracket 100 in the form of a flat surface which is mounted on a wall near a motor by means of bolts 102. A rigid arm is integrated with said flat surface 100 which radially protrudes from it, which engages opposite ends of a flat, circular band 106 which surrounds the upper side walls 28; ordinary devices are provided which are not shown for clamping said belt around said sidewalls 28. An annular recess 108 for accommodating a belt is preferably formed in said sidewalls to prevent the belt from slipping.

I praksis kan det være nødvendigt at tilføje yderligere olie på grund af det tab af olie, som er indeholdt i filtermaterialet 18 på det tidpunkt, hvor filterindretningen 12 5 bliver skiftet, men en motor, som er udstyret med den nye samling 10, som kommercielt er kendt som PREMO PLUS, behøver aldrig et olieskift.In practice, it may be necessary to add additional oil due to the loss of oil contained in the filter material 18 at the time the filter device 12 5 is changed, but an engine equipped with the new joint 10 as commercially available is known as PREMO PLUS, never need an oil change.
