Civilingeniør M.Gregersen._ (54) Smøresystem til stempelforhrændingsmotorer.Civil Engineer M.Gregersen._ (54) Lubrication system for piston combustion engines.

Opfindelsen angår et smøresystem til stempel forbrændingsmotorer og af den i krav l's indledning angivne art.The invention relates to a lubrication system for piston combustion engines and of the kind specified in the preamble of claim 1.

Fra tidsskriftet "Konstruktion", 1953, hæfte 7, side 232, er der kendt et sådant smøresystem, ved hvilket fordelernoten er udført med i det væsentlige halvcirkelformet tværsnit. Den smøreolietilførselsboring, der hører til fordelernoten, forløber i cylinderfladeområdet vinkelret på cylinderløbefladen og opviser i tilslutning hertil et hen mod cylindertopstykket stærkt stigende forløb.From the journal "Construction", 1953, booklet 7, page 232, there is known such a lubrication system in which the distributor note is made with substantially semicircular cross section. The lubricating oil supply bore belonging to the distributor nut extends in the cylinder surface area perpendicular to the cylinder running surface and, in turn, exhibits a strongly increasing course towards the cylinder head piece.

Denne kendte udformning af fordelernoten og af smøreolietilførselsboringen er dog forbundet med betydelige ulemper.However, this known design of the distributor nut and of the lubricating oil supply bore is associated with considerable disadvantages.

Ved udformningen af fordelernoten med halvcirkel formet tværsnit har fordelernoten hen mod overløbskanten en stærkt fal- U3042 2 den.de flanke, der ikke udøver nogen slags opstuvningsvirkning på smøreolien. Dette har til følge, at smøreolien allerede i området for smøreolietilførselsboringen i vidt omfang strømmer ud på cylinderløbefladen i stedet for at blive ledet gen-5 nem fordelernoten i cylinderens omkredsretning. Fordelernoten forbliver således næsten virkningsløs.In designing the semi-circular cross-sectional distributor note, the distributor note toward the overflow edge has a strongly folded edge which does not exert any kind of buoyancy effect on the lubricating oil. As a result, in the area of the lubricating oil bore, the lubricating oil extends to the cylinder run surface to a large extent instead of being guided through the distributor note in the circumferential direction of the cylinder. The distributor note thus remains almost ineffective.

Denne uønskede effekt bliver yderligere forstærket ved ovenfor nævnte udformning af smøreolietilførselsboringen, der næsten befordrer et ukontrollerbart udløb eller en overstrøm-10 ning af smøreolien i udløbsområdet for smøreolietilførselsboringen. Den kendte udførelse af fordelernoten og af smøreolietilførselsboringen har altså - hvis den aksiale udstrækning af noten er mindre end stempelringhøjden - til følge, at der, bortset fra, at der strømmer alt for megen smøreolie 15 ud, praktisk talt ikke sker nogen fordeling af smøreolien i sideretningen fra smøreolietilførselsboringen. Til trods for et alt for stort smøreolieforbrug opnås der således kun en mangelfuld, ujævn smørevirkning.This undesirable effect is further enhanced by the above-mentioned design of the lubricating oil bore, which virtually conducts an uncontrollable outlet or overflow of the lubricating oil in the lubricating oil supply bore outlet area. Thus, the known embodiment of the distributor nut and of the lubricating oil bore - if the axial extent of the groove is less than the piston ring height - results that, except that too much lubricating oil 15 flows out, there is practically no distribution of the lubricating oil in the the side direction from the lubricating oil supply bore. Thus, despite excessive lubricating oil consumption, only a deficient, uneven lubricating effect is achieved.

Udføres fordelernoten således, at dens aksiale ud-20 strækning er større end den aksiale udstrækning af en enkelt stempelring, kan gasser fra forbrændingsrummet strømme gennem fordelernoten. Denne gennemblæsning af varm gas bevirker så nok en vis oliefordeling i omkredsretning, men samtidig vil en vis oliemængde fordampe på grund af gennemblæsningen af dis-25 se gasser og forbrænder, hvad der medfører et forøget olieforbrug. Yderligere når forbrændingsprodukter sammen med den forbrændte cylindersmøreolie ned under stempelringene og forårsager en stærk tilsmudsning af løbsfladerne og slidserne.If the distributor note is designed so that its axial extent is greater than the axial extent of a single piston ring, gases from the combustion chamber can flow through the distributor note. This hot gas blow-through probably causes a certain circumferential oil distribution, but at the same time a certain amount of oil will evaporate due to the blowing of these gases and combustion, which results in increased oil consumption. In addition, combustion products, along with the burned cylinder lubricating oil, reach below the piston rings and cause a strong soiling of the tread surfaces and slots.

Den foreliggende opfindelse tager sigte på at angive et 30 smøresystem af den omhandlede art, ved hvilket man kan opnå, at smøreolien uden hjælp fra gennemblæsende gasser, der giver en tilsmudsning, bliver fordelt til siden fra smøreolietilførselsboringen over hele længden af fordelernoten, og at der fra smøreolietilførselsboringen kun strømmer så megen olie bort, 35 som det er nødvendigt til en jævn fødning af fordelernoten.SUMMARY OF THE INVENTION The present invention aims to provide a lubrication system of the kind in which the lubricating oil can be obtained, without the aid of blowing gases giving a soiling, distributed laterally from the lubricating oil supply bore over the entire length of the distributor nut, and from the lubricating oil supply bore, only as much oil flows away as is necessary for smooth feeding of the distributor nut.

Dette opnås ifølge opfindelsen ved, at smøresystemet er udformet som angivet i krav l's kendetegnende del.This is achieved according to the invention in that the lubrication system is designed as defined in the characterizing part of claim 1.

Ved denne udformning kan man opnå, at smøreolietilfør- 3 143042 seisboringen virker som opstuvningsrum for smøreolien, og at der opnås en bortstrømning af smøreolien til siden og i det væsentlige for oven langs fordelernoten, idet fordelernoten selv har en ekstra opstuvningsvirkning. Smøreolien kan altså 5 fordele sig langs hele fordelernoten jævnt over cylinderløbe-fladen, hvorved der kan opbygges en væsentlig mere jævn smøreoliefilm mellem stemplet og cylindervæggen. Sliddet på cylindervæggen og på stemplet kan herved ikke blot nedsættes, men også blive fordelt mere jævnt. Service-intervallerne bliver 10 herved betydelig længere, og vedligeholdelsesomkostningerne for motoren betydeligt lavere.In this embodiment, it can be achieved that the lubricating oil bore acts as a lubrication space for the lubricating oil, and that a lubrication of the lubricating oil is achieved sideways and substantially above the distributor nut, the distributor nut itself having an additional buoyancy effect. The lubricating oil can thus be distributed evenly throughout the distributor nut over the cylinder running surface, whereby a substantially more even lubricating oil film can be built up between the piston and the cylinder wall. The wear on the cylinder wall and on the piston can thereby not only be reduced, but also distributed more evenly. The service intervals thereby become significantly longer and the maintenance costs for the engine considerably lower.

I denne sammenhæng skal der henvises til, at en smøreolietilførselsboring med et i forhold til cylinderløbefladen skråt stigende forløb nok er kendt fra det tyske fremlæggel -15 sesskrift nr. 18 15 626, men den kendte smøreolietilførselsboring udmunder direkte og uden fordelernot i cylinderløbefladen.In this connection, it should be noted that a lubricating oil supply bore with a gradient increasing relative to the cylinder running surface is known from German submission -15 Session No. 18 15 626, but the known lubricating oil supply bore directly and without distributor note in the cylinder running surface.

Ved udformning af smøresystemet som angivet i krav 2 kan man opnå et maksimalt opstuvningsrum for smøreolien bag 20 ved overløbskanten.By designing the lubrication system as claimed in claim 2, a maximum storage space for the lubricating oil behind 20 can be obtained at the overflow edge.

Opfindelsen forklares nærmere under henvisning til tegningen, på hvilken fig. 1 viser en smøreolietilførselsboring med en fordelingsnot ved udførelsesformen for smøresy-25 stemet i stor målestok og set forfra, fig. 2 et snit efter en linie 11 -11 i fig. 1, fig. 3 en anden udførelsesform for fordelernoten og fig. 4 et snit efter en linie IV-IV i fig. 3.The invention is further explained with reference to the drawing, in which: FIG. 1 is a front view of a lubricating oil supply bore with a distribution groove in the embodiment of the lubricating system; FIG. 2 is a sectional view taken along line 11-11 of FIG. 1, FIG. 3 shows another embodiment of the distributor note and FIG. 4 is a sectional view taken along line IV-IV of FIG. Third

En fordelernot 1, der er forbundet med en smøreolietil-30 førselsboring 4, fig. 1, forløber på kendt måde udgående fra smøreolietilførselsboringen skråt nedefter til begge sider i forhold til omkredsretningen. Smøreolietilførselsboringen 4 er på kendt måde anbragt skråt. Niveauet for den olie, der strømmer ud af smøreolietilførselsboringen 4, er betegnet med 8. Det nederste 35 af de to notkanter, der ligger i cylinderens løbeflade 2, er udformet som en overløbskant 9, der altså ligger i samme plan som olieniveauet 8. Strømningsretningen for olien er angivet ved hjælp af pile 10 og 11, og notdybden er betegnet med 12.A distributor note 1 connected to a lubricating oil supply bore 4, FIG. 1, in a known manner, proceeds from the lubricating oil supply bore downwardly to both sides in relation to the circumferential direction. The lubricating oil supply bore 4 is disposed in a known manner obliquely. The level of the oil flowing out of the lubricating oil bore 4 is denoted by 8. The bottom 35 of the two groove edges located in the barrel surface 2 is formed as an overflow edge 9, which is in the same plane as the oil level 8. The flow direction for the oil is indicated by arrows 10 and 11 and the groove depth is indicated by 12.

4 143042 Sammen med en nederste notvæg 13a, der over sin hele længde, set i radialretning, har et bagud i forhold til cylinderløbefladen skråt forløb og udgår fra overløbskanten 9, danner en bagvæg 14a i noten en opstuvningsrende 15. Denne opstuv-5 ningsrende 15 tjener som fordelingsrende i omkredsretningen, fra hvilken rende der ved stemplets overstrygning strømmer bort en oliemængde, der er jævnt fordelt over hele notlængden. Den nederste kant på smøreolietilførselsboringen 4 skærer, set i radialplan, den nederste notvæg 13a i dennes dybeste punkt. Den 10 nederste notvæg 13a kan være plan eller have en rendeagtig form. Da det ovenfor beskrevne, bagud faldende forløb og den rendeagtige form af den nederste notvæg er forbundet med en forholdsvis høj indsats under fremstillingen, kan man også vælge en nederste notvæg, som den er vist i fig. 3 og 4, idet den ne-15 derste notvæg 13b, set i radial retning, har et plant, i forhold til cylinderløbefladen vinkelret forløb. Idet smøreolietilførselsboringen 4 skærer den nederste notvæg 13b i en vis afstand fra overløbskanten 9, regnet fra notens bagvæg 14a højest indtil den halve notdybde 12, set i retning hen mod cylinderlø-20 befladen, forhindres det, at olien fra det dannede opstuvnings-rum 15a kan strømme direkte ud på cylinderløbefladen. I stedet for opnår man, at oliefilmen fra opstuvningsrummet 15a kan strømme som over en gavlflade til den nederste plane og vinkelret på cylinderløbefladen 2 anbragte notvæg 13b indtil notens 2 5 ende.Together with a lower groove wall 13a, which over its entire length, seen in radial direction, has a backward inclination with respect to the cylinder running surface and exits from the overflow edge 9, a rear wall 14a in the groove forms a puffing ring 15. This puffing ring 15 serves as a circumferential distribution channel, from which a flow of oil is dispensed by an overflow of the piston, evenly distributed throughout the groove length. The lower edge of the lubricating oil bore 4 cuts, seen in radial plane, the lower groove wall 13a at its deepest point. The lower groove wall 13a may be planar or of a spindle shape. Since the above described backward course and the purely shaped form of the lower groove wall are associated with a relatively high insert during manufacture, a lower groove wall as shown in FIG. 3 and 4, the lower groove wall 13b, viewed in the radial direction, having a plane perpendicular to the barrel running surface. As the lubricating oil supply bore 4 cuts the lower groove wall 13b at a certain distance from the overflow edge 9, calculated from the back wall 14a of the groove at most up to half the groove depth 12, in the direction towards the barrel surface 20, it prevents the oil from the formed storage space 15a. can flow directly onto the cylinder running surface. Instead, it is obtained that the oil film from the stowage compartment 15a can flow as over a gable surface to the lower plane and perpendicularly to the cylinder running surface 2, groove wall 13b is placed up to the end of the groove. 1. Smøresystem for løbefladen i cylindre i forbrændingsmotorer, hvilke cylindre optager med stempelringe forsynede stempler, med. mindst én i cylindervæggen anbragt smøreolietilførselsboring med en fordelernot, der i mundingsområ-30 det for boringen på cylinderløbefladesiden udgår til begge sider og i forhold til omkredsretningen forløber skråt nedefter, og ved hvilken fordelernot en i cylinderløbefladen liggende nederste kant tjener som overløbskant for den smøreolie, der skal fordeles, kendetegnet ved, at smøreolietilfør-35 seisboringen 4 stiger hen mod fordelernoten, at endvidere den fra overløbskanten udgående notvæg (13a, 13b) over sin hele1. Lubrication system for the running surface of cylinders in internal combustion engines, which cylinders receive pistons with pistons. at least one lubricating oil supply bore disposed in the cylinder wall with a distributor note extending in the mouth area of the drilling on the cylinder surface side on both sides and extending in relation to the circumferential direction, and at which distributor note a lower edge lying in the cylinder running surface serves as an overflow edge for the lubricating oil. to be distributed, characterized in that the lubricating oil bore 4 rises towards the distributor note, furthermore, the net wall (13a, 13b) extending from the overflow edge throughout
