Description
hvilke motstanden 8 er anbrakt. Strimmelen 13 har i tverr-gående retning et antall tenner 14 som er bøyd mot strimmelen 12 slik at det er oppnådd et kompakt bånd 11. De i lengde-retningen motsatte ender av strimmelen 13 er bøyd 90° og gir opphav til respektive tunger 15, 16 av hvilke hver har et gjennomgående hull (ikke vist) som er i inngrep med skaftet på en bolt 17. Motstanden 8 og båndet 11 er fremstilt av et plastisk deformerbart materiale, slik at båndet 11 kan vikles rundt filtre av forskjellige diametre og tilpassestil formen på de nevnte filtre. which the resistor 8 is placed. In the transverse direction, the strip 13 has a number of teeth 14 which are bent towards the strip 12 so that a compact band 11 is obtained. The lengthwise opposite ends of the strip 13 are bent 90° and give rise to respective tongues 15, 16 each of which has a through hole (not shown) which engages with the shaft of a bolt 17. The resistor 8 and the band 11 are made of a plastically deformable material, so that the band 11 can be wrapped around filters of different diameters and adapted to the shape on the aforementioned filters.
På filterets 2 skålformede legeme 3 er fastskrudd . en termisk bryter 19 som på ikke vist måte omfatter et bi-metallisk bryterelement som vanligvis er åpent når filterets temperatur er høyere enn f.eks. -5° C, og er lukket når temperaturen er lavere enn den nevnte verdi. To forbindelses-kabler 21 og 22 strekker seg fra den termiske bryter 19. The bowl-shaped body 3 of the filter 2 is screwed on. a thermal switch 19 which, in a manner not shown, comprises a bi-metallic switch element which is usually open when the filter's temperature is higher than e.g. -5° C, and is closed when the temperature is lower than the mentioned value. Two connection cables 21 and 22 extend from the thermal switch 19.
Som vist på fig. 2, er det mellom to klemmer 23 og 24, som kan koples til respektive poler av en elektrisk energikilde, parallellkoplet to grener av hvilke den første i serie omfatter den bimetalliske, termiske bryter 19 og en spole 26 på et relé, og den andre i serie omfatter motstanden 8 og et kontaktelement 27 av den normalt åpne type som påvir-kes av spolen 26. As shown in fig. 2, there are between two terminals 23 and 24, which can be connected to respective poles of an electrical energy source, two branches connected in parallel, the first of which in series comprises the bimetallic, thermal switch 19 and a coil 26 of a relay, and the second in series comprises the resistor 8 and a contact element 27 of the normally open type which is affected by the coil 26.
Som vist på fig. 1, er det rundt båndet 11 også anbrakt en strimmel 18 som er fremstilt av varmeisolerende materiale. As shown in fig. 1, a strip 18 made of heat-insulating material is also arranged around the band 11.
Monteringen av oppvarmingsanordningen 1 utføres på meget enkel måte ved at båndet 11 formes rundt filteret 2 og båndets 11 tunger 15 og 16 strammes ved hjelp av bolten 17. Anordningens virkemåte skal nå beskrives idet det antas at The assembly of the heating device 1 is carried out in a very simple way by forming the band 11 around the filter 2 and the tongues 15 and 16 of the band 11 are tightened using the bolt 17. The device's operation will now be described assuming that
den temperaturverdi som detekteres av den termiske bryter 19,the temperature value detected by the thermal switch 19,
i begynnelsen er mindre enn -5° C. Idet det henvises til fig. 2, er den termiske bryter 19 under sådanne forhold lukket, spolen 26 er aktivert og kontaktelementet 27 er følgelig lukket. I motstanden 8 flyter derfor en elektrisk strøm som forårsaker oppvarming av motstanden. at the beginning is less than -5° C. Referring to fig. 2, the thermal switch 19 is under such conditions closed, the coil 26 is activated and the contact element 27 is consequently closed. An electric current therefore flows in the resistor 8, which causes heating of the resistor.
Idet det igjen henvises til fig. 1, blir den varme-energi som frembringes av motstanden 8, overført til filterets Referring again to fig. 1, the heat energy produced by the resistor 8 is transferred to the filter
Oppfinnelsen angår en oppvarmingsanordning som kan anvendes på et brennstoff-filter. The invention relates to a heating device that can be used on a fuel filter.
Det er velkjent at det brennstoff som anvendes på dieselmotorer, også inneholder små mengder av parafin. It is well known that the fuel used in diesel engines also contains small amounts of kerosene.
Dette stoff haf den ulempe at det størkner ved lave temperaturer, særlig ved temperaturer på mindre enn 0° C, slik at det øker tilstoppingen av både brennstoffledningene og hoved-eller sekundærfiltrene som er anordnet i ethvert matesystem på en diselmotor. This substance has the disadvantage that it solidifies at low temperatures, especially at temperatures of less than 0° C, so that it increases the clogging of both the fuel lines and the main or secondary filters arranged in any feed system on a diesel engine.
Det er et formål med oppfinnelsen å tilveiebringe en anordning som vil gjøre det mulig å unngå den ovennevnte ulempe på en enkel og billig måte. It is an object of the invention to provide a device which will make it possible to avoid the above-mentioned disadvantage in a simple and inexpensive way.
Ifølge oppfinnelsen er det tilveiebrakt en oppvarmingsanordning som er innrettet til å benyttes sammen med et brennstoff-filter, og som er kjennetegnet ved at den omfatter i det minste en formbar, elektrisk motstand, og et formbart bånd som er viklet rundt motstanden og er innrettet til å vikles rundt filteret. According to the invention, a heating device is provided which is designed to be used together with a fuel filter, and which is characterized in that it comprises at least a malleable electrical resistance and a malleable band which is wrapped around the resistance and is arranged to to wrap around the filter.
Oppfinnelsen skal beskrives nærmere i det følgende i forbindelse med et utførelseseksempel under henvisning til tegningen, der fig. 1 viser et perspektivriss sett ovenfra av en oppvarmingsanordning ifølge oppfinnelsen som er vist montert i et anvendelseseksempel, og fig. 2 viser et elektrisk skjema av en styrekrets i anordningen på fig. 1. The invention shall be described in more detail in the following in connection with an exemplary embodiment with reference to the drawing, where fig. 1 shows a perspective view seen from above of a heating device according to the invention which is shown mounted in an application example, and fig. 2 shows an electrical diagram of a control circuit in the device of fig. 1.
I utførelsen på fig. 1 betegner henvisningstallet 1 generelt en oppvarmingsanordning som er innrettet til å In the embodiment in fig. 1, the reference number 1 generally denotes a heating device which is arranged to
anvendes på et brennstoff-filter 2. Brennstoff-filteret 2 har en i hovedsaken sylindrisk konstruksjon og omfatter et nedre, i hovedsaken skålformet legeme 3 som er lukket i sitt øvre parti ved hjelp av et lokk 4, idet legemet og lokket er utformet med rørledninger 5 hhv. 6 for utstrømning og mating av brennstoffet. is used on a fuel filter 2. The fuel filter 2 has a mainly cylindrical construction and comprises a lower, mainly bowl-shaped body 3 which is closed in its upper part by means of a lid 4, the body and the lid being designed with pipelines 5 respectively 6 for outflow and feeding of the fuel.
Oppvarmingsanordningen ifølge oppfinnelsen omfatter i hovedsaken en elektrisk motstand 8 som er forsynt med til-koplingstråder eller tilkoplingsklemmer 9 og 10,,og et formbart bånd 11 som omgir motstanden langs hele dens lengde, idet bare klemmene 9 og 10 etterlates frie. Båndet 11 er spesielt sammensatt av to plane strimler 12 hhv. 13 mellom 2 skålformede legeme 3 og fra sistnevnte til det brennstoff som flyter i dette, og forårsaker dermed en gradvis økning av temperaturen, for å lette oppløsningen av partiklene av parafin som er inneholdt i brennstoffet. Når temperatur-verdien blir høyere enn den forutbestemte minimumsverdi (f.eks. +5° C), åpner den termiske bryter 19 med påfølgende avbrytelse av tilførselen til spolen 26 og, ved hjelp av den sistnevnte, til motstanden 8. Den kombinerte virkning av motstanden 8 og den termiske bryter 19 gjør det under alle omstendigheter mulig å opprettholde temperaturen i filteret 2 over den forutbestemte minimumsverdi. The heating device according to the invention mainly comprises an electrical resistance 8 which is provided with connecting wires or connecting terminals 9 and 10, and a malleable band 11 which surrounds the resistor along its entire length, leaving only the terminals 9 and 10 free. The tape 11 is specially composed of two flat strips 12 respectively. 13 between 2 bowl-shaped bodies 3 and from the latter to the fuel flowing therein, thereby causing a gradual increase in temperature, to facilitate the dissolution of the particles of kerosene contained in the fuel. When the temperature value becomes higher than the predetermined minimum value (e.g. +5° C), the thermal switch 19 opens with subsequent interruption of the supply to the coil 26 and, by means of the latter, to the resistor 8. The combined effect of the resistance 8 and the thermal switch 19 make it possible under all circumstances to maintain the temperature in the filter 2 above the predetermined minimum value.
Ut fra analysen av egenskapene til oppvarmingsanordningen 1 ifølge oppfinnelsen vil det innses at anordningen gjør det mulig å overvinne de foran omtalte ulemper. Spesielt er anordningen ifølge oppfinnelsen meget lett å montere, og den kan dessuten tilpasses til enhver type filter, forutsatt at systemet for sammenkopling mellom tungene 15 og 16 til slutt utskiftes i overensstemmelse med dimensjonene til det filter som skal oppvarmes. Den ytterst enkle konstruksjon av anordningen 1 gjør det mulig å redusere fremstillingsom-kostningene for selve filteret til et minimum, mens den respektive styrekrets som er vist på fig. 2, tillater anordningen 1 å arbeide på fullstendig automatisk måte. Based on the analysis of the properties of the heating device 1 according to the invention, it will be realized that the device makes it possible to overcome the disadvantages mentioned above. In particular, the device according to the invention is very easy to assemble, and it can also be adapted to any type of filter, provided that the system for coupling between the tongues 15 and 16 is eventually replaced in accordance with the dimensions of the filter to be heated. The extremely simple construction of the device 1 makes it possible to reduce the manufacturing costs for the filter itself to a minimum, while the respective control circuit shown in fig. 2, allows the device 1 to work in a fully automatic manner.
Endelig er det klart at mange modifikasjoner og variasjoner kan gjøres av oppvarmingsanordningen 1 og den respektive, elektroniske styrekrets uten å avvike fra opp-finnelsens ramme. For eksempel kan mange variasjoner utføres av konstruksjonen av filteret 2. Spesielt kunne båndet 11 fremstilles av et kontinuerlig legeme ved hjelp av silicon-gummi, og motstanden 8 kunne være dannet av et antall mot-, stander i parallell. Den på fig. 2 viste styrekrets kunne modifiseres på mange måter, for eksempel ved å anbringe bry-teren 19 direkte i serie med motstanden 8, eller ved å erstat-te den termiske bryter 19 med en manuelt påvirkbar bryter anbrakt på dashbordet på et motorkjøretøy. Endelig kan oppvarmingsanordningen 1 anvendes på hvilket som helst brennstoff-filter i et motorkjøretøy, spesielt også på det filter som er anbrakt rundt sugerøret i brennstofftanken i et kjøretøy, og i hvilken som helst anordning i hvilken brennstoffet sirkulerer. Finally, it is clear that many modifications and variations can be made to the heating device 1 and the respective electronic control circuit without deviating from the scope of the invention. For example, many variations can be made of the construction of the filter 2. In particular, the band 11 could be made of a continuous body using silicon rubber, and the resistance 8 could be formed by a number of resistances in parallel. The one in fig. 2 shown control circuit could be modified in many ways, for example by placing the switch 19 directly in series with the resistor 8, or by replacing the thermal switch 19 with a manually actuated switch placed on the dashboard of a motor vehicle. Finally, the heating device 1 can be used on any fuel filter in a motor vehicle, especially also on the filter that is placed around the suction pipe in the fuel tank of a vehicle, and in any device in which the fuel circulates.
