Description
8100546-4- -~~'f fl åtminstone en av dessa konstruktionsdetaljer som bestämmer genom- strömningsarean tillförs värmeenergin direkt och med minsta förluster vid munstyckets kritiska ställe. Värmeförluster minimeras. Eftersom endast relativt små materialmassor i munstycksområdet behöver uppvär- mas, räcker det med låg värmeeffekt, vilket är av särskild betydelse dfranlför allt l de fall då varmeefferten måste reduceras ment lljalp av ett batteri. 8100546-4- - ~~ 'f fl at least one of these design details that determines the flow area is supplied with the heat energy directly and with the least losses at the critical location of the nozzle. Heat losses are minimized. Since only relatively small masses of material in the nozzle area need to be heated, low heat output is sufficient, which is of particular importance especially in cases where the heat output must be reduced by means of a battery.
Med hänsyn till det ringa effektbehovet kan man låta den elektriska värmeapparaten vara inkopplad under värmedonets hela arbets- tid. I de fall då det anses önskvärt att koppla ifrån värmeapparaten så snart som brännaren uppnått sin arbetstemperatur kan detta ske via brännarens styrdon. Genom att bränslet förfärmes i omedelbar närhet av den minsta genomströmningsarean blir det möjligt att använda speciellt _ små munstycken. W När mnnstycket sitter inuti virvelinsatsen kan denna särskilt snabbt upphettas med liten energi.With regard to the low power requirement, the electric heater can be switched on during the entire working time of the heating device. In cases where it is considered desirable to disconnect the heater as soon as the burner has reached its operating temperature, this can be done via the burner's controls. By preheating the fuel in the immediate vicinity of the smallest flow area, it becomes possible to use especially small nozzles. W When the nozzle is inside the vortex insert, it can be heated particularly quickly with little energy.
När däremot munstycket är utformat som ett returmunstycke in- monteras värmeapparaten företrädesvis inuti munstyckskroppens framgavel.On the other hand, when the nozzle is designed as a return nozzle, the heater is preferably installed inside the front end of the nozzle body.
I dylikt fall bortföres nämligen returolja via virvelinsatson. Genom denna olja bortföres värme från spiralinsatsen.In such a case, return oil is removed via the vortex insert. Through this oil, heat is removed from the spiral insert.
~Värmeapparaten kan bestå av åtminstone en i en urborrning i den ifrågavarande munstycksdetaljen insatt värmepatron. I stället för eller som tillägg till denna kan värmeapparaten bestå av åtminstone en värme- slinga som.monteras in i den ifrågavarande munstyeksdetaljen.The heating device may consist of at least one heating cartridge inserted in a bore in the nozzle part in question. Instead of or in addition to this, the heater may consist of at least one heating loop which is mounted in the nozzle part in question.
Uppfinningen klargöres ytterligare av de föredragna utförings- formerna enligt ritningen, på vilken rig 1 visar i stark förstoring ett simplexmunstycke med uppvärmd virvelinsats, fig 2 visar en virvel- dinsats för ett munstycke av det i fig 1 visade slaget med en modifierad utföringsform av värmeapparaten och fig 3 visar ävenledes i stark för~ estorin- en län sektion av ett enlißt u'lfinnin en utformat retur- O munstycke. _ Det i fi 1 åskådlive'orda sim lezrmnstrcket omfattar såsom är g _ usa o] I förut känt, en munstyckskropp 1 i vars främre del en virvelinsats 2 är _anordnad. Virvelinsatsen 2 har en i form av en stynpad kon utbildad Iramgavel 3 i vilken ett flertal på förutbestämda.vinkelnvstånd li33nn~ de slitsar 4 är utformade. Spiralinsatsen 2 pressas medelst en i mun» styckskroppen 1 inskruvad skruvinsats'5, vilken med ansatser 6 anlig~ _ ger mot en skuldra 7 på virvelinsatsen 2, mot en iuå komiskt utstju- tande framgavel Hdpå munstyckskroppen 1. I munstyckskroppens 1 bakre sände är en filterhållare 9 inskruvad, vilken i detta utiöringsexempel P00 I ÄALIITÜ; 8100546-4 uppbär ett som en yorös sinterenhet utformat filter 10.The invention is further elucidated by the preferred embodiments according to the drawing, in which rig 1 shows at high magnification a simplex nozzle with heated vortex insert, Fig. 2 shows a vortex insert for a nozzle of the type shown in Fig. 1 with a modified embodiment of the heater and Fig. 3 also shows in strong for estorin- a county section of a single u'lfinnin a designed return nozzle. As can be seen from the prior art, the nozzle body comprises, as is known in the art, a nozzle body 1 in the front part of which a vortex insert 2 is arranged. The vortex insert 2 has a frame end 3 formed in the form of a truncated cone in which a plurality of the slots 4 are formed at predetermined angular distances. The spiral insert 2 is pressed by means of a screw insert 5 screwed into the nozzle body 1, which with abutments 6 abuts against a shoulder 7 on the vortex insert 2, against a slightly comically projecting front end of the nozzle body 1. At the rear end of the nozzle body 1 is a filter holder 9 screwed in, which in this exemplary embodiment P00 I ÄALIITÜ; 8100546-4 carries a filter 10 designed as a yorous sinter unit.
Under drift införes flytande bränsle, särskilt olja, genom filtret 10 i munstycket. Oljan genomströmmar filterhållaren 9 och skruxe insatsen 5. Den passerar slitsen 4 för att slutligen lämna munstyoket via en öppning 12.During operation, liquid fuel, especially oil, is introduced through the filter 10 into the nozzle. The oil flows through the filter holder 9 and screws the insert 5. It passes the slot 4 to finally leave the nozzle via an opening 12.
.I den exempelvis som en keramkropp utformade virvelinsatsen 2 är en värmeslinga 13 inlagd. Värmeslingan 13 matas med elektrisk energi via tilledningar 14. Vid kallstart åstadkommas en snabb upphettning av den relativt obetydliga godsmassan som omger slitsarna 4. Därigenom får man på mycket kort tid en synnerligen effektiv upphettning av det genom slitsarna 4 matade bränslet, vilket säkrar en acceptabel finfördelning även vid hög viskositet hos bränslet och låg utetomyeratur.In the vortex insert 2 designed, for example, as a ceramic body, a heating loop 13 is inserted. The heating coil 13 is supplied with electrical energy via lines 14. During a cold start, the relatively insignificant mass of goods surrounding the slots 4 is rapidly heated. This results in a very efficient heating of the extremely efficient fuel fed through the slots 4, which ensures an acceptable atomization. even at high viscosity of the fuel and low outdoor temperature.
Vin nu vürmoring 15 kan om så önskan ytterligare uppvärmning av munstyckskroppen 1 ernàs.Vin nu vürmoring 15 can, if desired, further heating of the nozzle body 1 is achieved.
På motsvarande vis kan enligt fig 2 i stället för värmeslingan en värmepatron 17 användas, vilken är inskjuten i en urborrning 18 i spiralinsatsen 2.Correspondingly, according to Fig. 2, instead of the heating loop, a heating cartridge 17 can be used, which is inserted into a bore 18 in the spiral insert 2.
Fig 3 visar ett returmunstycke med en munstyckskropp 20, vars främre gavelvägg är bildad av en munstycksplatta 21. I främre delen av munstyckskroppen 20 sitter en virvelinsats 22, som tillsammans med mune stycksplattan 21 avgränsar slitsarna 24 för bränslegenomströmningen. En i munstyokskroppen 20 inskruvad skruvinsats 25 anligger mot en tätnings- ring 26, som å sin sida vilar mot en skuldra 27 på virvelinsatsen 22.Fig. 3 shows a return nozzle with a nozzle body 20, the front end wall of which is formed by a nozzle plate 21. In the front part of the nozzle body 20 there is a vortex insert 22, which together with the nozzle plate 21 delimits the slots 24 for the fuel flow. A screw insert 25 screwed into the nozzle body 20 abuts against a sealing ring 26, which in turn rests against a shoulder 27 on the vortex insert 22.
I munstyckskroppen 20 är vidare inskruvad en filteranordning 28 med ett bränslefilter 29.A filter device 28 with a fuel filter 29 is further screwed into the nozzle body 20.
I fallet returmunstycke har virvelinsatsen 22 en längsgående urborrning 30 i centrum, vilken i sin från munstycksplattan 21 vända ande är tillsluten medelst en tätningsring 31 och en ventillnJo.32.In the case of the return nozzle, the vortex insert 22 has a longitudinal bore 30 in the center, which in its spirit facing away from the nozzle plate 21 is closed by means of a sealing ring 31 and a valve 32.
Ventilkulan 52 hållas tryckt mot tätningsringen 31 medelst en mellan fjädertallrikarna 34, 35 befintlig ventilfjäder 33. Fjäderkraften kan regleras medelst en i skruvinsatsen 25 inskruvad, genomborrad regle- ringsskruv 36.The valve ball 52 is kept pressed against the sealing ring 31 by means of a valve spring 33 present between the spring plates 34, 35. The spring force can be regulated by means of a adjusting screw 36 screwed into the screw insert 25.
Såsom pilar@a,37 visar, strömmar oljan genom filtret 29 och når genom öppningar i filterkroppen 28 in i rummet mellan munstyclskropyen 20 och skruvinsatsen 25. Oljan strömmar igenom slitsorna 24. En del av oljan lämnar munstyoket via.ett hål 38 i mnnstycksplattan 21. En annan genom fjaderkraften hos ventilfjädern 33 förutbestämd del av oljan strömmar bakåt genom det längsgående borrhålet BU i virvelinsatsen 22, varvid ventilkulan 32 nöjes från sitt säte på tätningsrirren 51. nenna olja bortföres baktill ur munstycket, såsom pilen 39 antyder. i.As arrows @ a, 37 show, the oil flows through the filter 29 and reaches through openings in the filter body 28 into the space between the nozzle body 20 and the screw insert 25. The oil flows through the slots 24. Part of the oil leaves the nozzle via a hole 38 in the nozzle plate 21 Another part of the oil predetermined by the spring force of the valve spring 33 flows backwards through the longitudinal bore BU in the vortex insert 22, the valve ball 32 being satisfied from its seat on the sealing groove 51. This oil is removed at the rear from the nozzle, as the arrow 39 indicates. in.
