Abstract
Anordning for stopping av en forbrenningsmotor ved overturtall.Device for stopping an internal combustion engine at overspeed.
Description
Oppfinnelsen vedrører en anordning for stopping av en forbrenningsmotor med brennstoffinnsprøyting i tilfelle av overturtall. The invention relates to a device for stopping an internal combustion engine with fuel injection in the event of overspeed.
Ved forbrenningsmotorer med brennstoffinnsprøyting er det kjent anordninger hvor i.tilfelle av overturtall hos motoren et tur-tallfølsomt eller av overturtallet påvirket utløsningsorgan åpner en trykkfluidumventil for tilførsel av trykkfluidum til en eller flere manøversylindre eller lignende servomotorer, hvis stempler virker på de tannstenger som styrer brennstoffinnsprøyt-ningspumpene, slik at brennstoffinnsprøytningen fra samtlige brennstoffpumper brytes. En markant ulempe ved disse kjente anordninger er at de ikke kan virke om tannstangen eller de mek-aniske overføringsorganer mellom manøversylindrene og tannstangen låses fast eller sperres på grunn av en eller annen feil. In the case of internal combustion engines with fuel injection, devices are known where, in the event of overspeed in the engine, a speed-sensitive or overspeed-affected release device opens a pressure fluid valve for the supply of pressure fluid to one or more maneuvering cylinders or similar servomotors, whose pistons act on the racks that control fuel injection injection pumps, so that the fuel injection from all fuel pumps is interrupted. A marked disadvantage of these known devices is that they cannot work if the rack or the mechanical transmission means between the maneuvering cylinders and the rack are locked or blocked due to some fault.
Det er også kjent anordninger for stopping av brennstoffinn-sprøytningspumpene, hvilke anordninger.innbefatter, hydrauliske sylindre som er anordnet på samtlige innsprøytningspumper og som i tilfelle av overturtall i motoren tilføres trykkfluidum, slik at hvert stempel i de hydrauliske sylindre forskyves og over en hevarm påvirker innsprøytningspumpens stempel, slik at dette skilles fra sin løftearm, støtstang eller lignende løfteorgan og fra sin drivkam. Ulempen ved slike anordninger er deres relative kompleksitet og de store omkostninger. There are also known devices for stopping the fuel injection pumps, which devices include hydraulic cylinders which are arranged on all injection pumps and which, in the event of an overspeed in the engine, are supplied with pressure fluid, so that each piston in the hydraulic cylinders is displaced and affects via a lifting arm the injection pump's piston, so that this is separated from its lifting arm, push rod or similar lifting device and from its drive cam. The disadvantage of such devices is their relative complexity and high costs.
Fra norsk utlegningsskrift nr. 136 160 er det kjent en inn-sprøytningspumpe med et føringselement mellom pumpestempelet og drivelementet. På hver pumpe er det montert en arbeids-sylinder. Ved rusing eller overturtall vil en ventil til- An injection pump with a guide element between the pump piston and the drive element is known from Norwegian design document no. 136 160. A working cylinder is mounted on each pump. When speeding or over-revving, a valve will
føre trykk til arbeidssylinderne og påvirke deres respektive stempler. Hvert stempel påvirker så føringselementet slik at forbindelsen mellom drivelementet og føringsstykket brytes. Denne tidligere kjente anordning virker riktignok tilfreds-stillende, men for at den skal kunne monteres i tilknytning til vanlige motorer av den type det her er tale om, kreves relativt omfattende monteringsarbeider og inngrep i motoren. conveying pressure to the working cylinders and affecting their respective pistons. Each piston then affects the guide element so that the connection between the drive element and the guide piece is broken. This previously known device certainly works satisfactorily, but in order for it to be able to be mounted in connection with ordinary motors of the type in question here, relatively extensive assembly work and interventions in the motor are required.
Ifølge oppfinnelsen er det tilveiebragt en anordning for ved overturtall å stoppe en forbrenningsmotor med brennstoff-innsprøyting ved hjelp av en brennstoffinsprøytningspumpe med et pumpestempel med konstant slaglengde, i hvilken pumpe et i pumpehuset forskyvbart føringselement er anordnet mellom pumpestempelet og pumpestempelets drivelement, hvilket førings-element begrenser et kammer som inneholder drivelementet, hvilken anordning innbefatter et system for ved overturtall å tilføre en komprimert gass til et rom med et stempel som ved gasspåvirkning skiller drivelementet fra føringselementet, idet det som kjennetegner anordningen ifølge oppfinnelsen er at føringselementet utgjør det nevnte stempel og at kammeret utgjør, det nevnte rom. Fordelaktig kan gass-systernet tilknyttes kammeret gjennom den nevnte avløpskanal. Når et andre kammer er anordnet mellom pumpestempelet og føringselementet kan fordelaktig det andre kammer være forsynt med organer, eksempelvis i form av en snøfteventil, en tilbakeslagsventil, en overtrykksventil eller en sikkerhetsventil, for tilveiebringelse av en forbindelse mellom det andre kammer og den omgivende atmosfære for utslipping av den trykkgass som eventuel lekker inn fra det førstnevnte kammer. According to the invention, a device is provided for stopping an internal combustion engine with fuel injection at overspeed by means of a fuel injection pump with a pump piston with a constant stroke length, in which pump a guide element that can be moved in the pump housing is arranged between the pump piston and the pump piston's drive element, which guide element restricts a chamber that contains the drive element, which device includes a system for supplying a compressed gas at overspeed to a room with a piston which separates the drive element from the guide element due to the influence of gas, the characteristic of the device according to the invention being that the guide element forms the said piston and that the chamber constitutes, the said room. Advantageously, the gas system can be connected to the chamber through the aforementioned drainage channel. When a second chamber is arranged between the pump piston and the guide element, the second chamber can advantageously be provided with means, for example in the form of a blow valve, a non-return valve, an overpressure valve or a safety valve, for providing a connection between the second chamber and the surrounding atmosphere for discharge of the pressurized gas that may leak in from the first-mentioned chamber.
Oppfinnelsen representerer en sterk forenkling av det tidligere system. Man eliminerer en del av det relativt kompliserte tilleggsutstyr og griper direkte inn i pumpen. Oppfinnelsen representerer således en ny og enkel og virkningsfull løsning på det foreliggende problem. Oppfinnelsen kan enkelt tillempes ved allrede forhåndenværende brennstoffpumper uten omfattende monteringsarbeider og inngrep. The invention represents a strong simplification of the previous system. One eliminates part of the relatively complicated additional equipment and intervenes directly in the pump. The invention thus represents a new and simple and effective solution to the present problem. The invention can be easily applied to existing fuel pumps without extensive assembly work and interventions.
Ved at gass-systemet tilknyttes kammeret gjennom den nevnte avløpskanal benyttes en slik forhåndenværende kanal for inn-slipping av gass for påvirkning av føringselementet, og dette gir en fordelaktig utførelse. Det trekk at det nevnte andre kammer kan bringes i forbindelse med atmosfæren gjennom en ventil medfører at man unngår en eventuell trykkoppbygging som følge av gasslekkasje forbi det som stempel virkende føringselement. In that the gas system is connected to the chamber through the aforementioned drain channel, such an existing channel is used for letting in gas to influence the guide element, and this provides an advantageous design. The feature that the aforementioned second chamber can be brought into contact with the atmosphere through a valve means that a possible pressure build-up as a result of gas leakage past the guide element acting as a piston is avoided.
Oppfinnelsen ska] beskrives nærmere under henvisning til tegningen, som mer skjematisk viser et snitt gjennom en fordelaktig utførelsesform av oppfinnelsen. Tegningen viser i lengde-snitt en brennstoffinnsprøytningspumpe forsynt med en nødstopp-anordning ifølge oppfinnelsen. The invention shall be described in more detail with reference to the drawing, which more schematically shows a section through an advantageous embodiment of the invention. The drawing shows a longitudinal section of a fuel injection pump equipped with an emergency stop device according to the invention.
Som nevnt er anordningen ifølge oppfinnelsen beregnet til i tilfelle av overturtall å stoppe en forbrenningsmotor med et brennstoffinnsprøytningssystem som innbefatter brennstoff-innsprøytningspumper av deplacementstypen med et frem- og tilbakegående stempel. Tegningen viser en slik brennstoff- As mentioned, the device according to the invention is intended to stop an internal combustion engine with a fuel injection system which includes displacement-type fuel injection pumps with a reciprocating piston in the event of overspeed.

A disk or chip
) 6 er forskyvbart montert i pumpens 1 pumpehus 7 mellom pumpestempelet 12 og dets drivelement 3. Denne skive 6 deler således pumpehuset 7 i to adskilte, lukkede kammere 8 og 9, hvorav det første inneholder pumpestempelet 12, mens det andre inneholder støtstangen eller drivelementet 3. Dette andre kammer 5 9 er i sin nedre del forsynt med en avløpskanal 10 for eventuell brennstofflekkasje fra pumpen. ) 6 is displaceably mounted in the pump housing 7 of the pump 1 between the pump piston 12 and its drive element 3. This disc 6 thus divides the pump housing 7 into two separate, closed chambers 8 and 9, the first of which contains the pump piston 12, while the second contains the push rod or the drive element 3 This second chamber 59 is provided in its lower part with a drainage channel 10 for any fuel leakage from the pump.
Pumpestempelet 12 kan også dreies ved hjelp av et drev 2 i fra en tannstang 11, slik at det er mulig å stille inn mengden inn-sprøytet brennstoff ved å dreie pumpestempelet 12 på i og for seg kjent måte. The pump piston 12 can also be turned by means of a drive 2 from a toothed rack 11, so that it is possible to set the amount of injected fuel by turning the pump piston 12 in a manner known per se.

ulike årsaker, f.eks. på grunn av fastskjærte lagre, skader på tannstangens eller drevets tenner, eller på grunn av inntrengt smuss eller urenheter. I slike tilfeller vil motoren få en ten-dens til å ruse,og det er derfor nødvendig å bryte brennstoff-innsprøytningen med én gang. Ifølge oppfinnelsen oppnår man dette ved at en komprimert gass, fortrinnsvis en inert gass, f.eks. kvelstoff eller kulldioksyd, ledes inn i pumpehusets nedre kammer 9, hvilket kammer inneholder støtstangen eller drivelementet 3 for pumpestempelet 12. Denne komprimerte gass har et så høyt trykk at den er istand til å overvinne kraften fra pumpestempelets 12 returfjær 13, og skiven eller brikken 6 og pumpestempelet 12 løftes derfor opp og skilles helt ifra den drivende støtstang 3. Støtstangen 3 kan da ikke lenger gi pumpestempelet 12 en frem- og tilbakegående arbeidsbevegelse, various reasons, e.g. due to jammed bearings, damage to the teeth of the rack or gear, or due to ingress of dirt or impurities. In such cases, the engine will have a tendency to rush, and it is therefore necessary to interrupt the fuel injection at once. According to the invention, this is achieved by a compressed gas, preferably an inert gas, e.g. nitrogen or carbon dioxide, is led into the pump housing's lower chamber 9, which chamber contains the push rod or drive element 3 for the pump piston 12. This compressed gas has such a high pressure that it is able to overcome the force from the pump piston 12's return spring 13, and the disk or chip 6 and the pump piston 12 is therefore lifted up and completely separated from the driving push rod 3. The push rod 3 can then no longer give the pump piston 12 a reciprocating working movement,
og brennstoffinnsprøytningen brytes og motoren stoppes. and the fuel injection is interrupted and the engine is stopped.
Tilføringen av komprimert gass til kammeret 9 i pumpehuset The supply of compressed gas to the chamber 9 in the pump housing
skjer på en enkel måte gjennom avløpskanalen 10 for lekkasjebrennstoff, hvilken kanal knyttes til en trykkgasskilde 15 ved hjelp av en utløsningsanordning 16 som er følsom for overturtall i motoren. takes place in a simple way through the drain channel 10 for leaking fuel, which channel is connected to a compressed gas source 15 by means of a release device 16 which is sensitive to overspeed in the engine.
Det øvre kammer 8 hvor pumpestempelet 12 er anordnet, er hen- ' siktsmessig forsynt med en lufteanordning 17 til den omgivende atmosfære, f.eks. en kalibrert overtrykksventil, en tilbakeslagsventil eller en enkel snøfteventil, slik at man unngår at det i kammeret 8 bygges opp et for høyt trykk som følge av trykkgass som lekker inn i kammeret 8 fra kammeret 9. På denne måten unngår man også en tilstopping av tannstangen 11 The upper chamber 8, where the pump piston 12 is arranged, is appropriately provided with a venting device 17 to the surrounding atmosphere, e.g. a calibrated overpressure valve, a non-return valve or a simple snuff valve, so that too high a pressure is built up in the chamber 8 as a result of compressed gas leaking into the chamber 8 from the chamber 9. In this way, clogging of the rack is also avoided 11
med smuss eller lekkasjebrennstoff, som eventuelt presses opp mot tannstangen under påvirkning av et overtrykk i kammeret 8. with dirt or leaking fuel, which may be pushed up against the rack under the influence of an overpressure in the chamber 8.
Den nye anordning er betydelig enklere enn tidligere kjente anordninger for samme formål og er også mer driftssikker. The new device is significantly simpler than previously known devices for the same purpose and is also more reliable.
Skiven eller brikken 6 kan, som i det viste og beskrevne ut-førelseseksempel, være slik utformet at den helt adskiller kammerne 8 og 9 fra hverandre, eller den kan være forsynt med gjennomgående hull, som gir forbindelse mellom kammerne 8 og 9, og disse hull er da forsynt med ventiler som mulig-gjør en strømning av kromprimert gass bare fra kammeret 8 til kammeret 9. Oppfinnelsen kan således meget enkelt an-vendes på tidligere kjente brennstoffpumper. The disk or piece 6 can, as in the shown and described embodiment, be designed in such a way that it completely separates the chambers 8 and 9 from each other, or it can be provided with through holes, which provide a connection between the chambers 8 and 9, and these holes are then provided with valves which enable a flow of chrome-primed gas only from chamber 8 to chamber 9. The invention can thus be very easily applied to previously known fuel pumps.
