Description
i 150277in 150277
Opfindelsen angår en oliebeholder af den i krav l's indledning angivne art.The invention relates to an oil container of the kind specified in the preamble of claim 1.
Sådanne oliebeholdere anvendes f.eks. ved hydrauliske styreanlæg. Ved driften af sådanne styreanlæg aftager 5 en højtrykspumpe olien fra beholderen, medens på den anden side olien føres tilbage til beholderen efter først at have passeret et filter.Such oil containers are used e.g. for hydraulic steering systems. In the operation of such control systems, a high-pressure pump removes the oil from the vessel, while on the other hand the oil is returned to the vessel after first passing a filter.
Ved en kendt oliebeholder af ovennævnte art (tysk fremlæggelsesskrift nr. 1 036 817) er umiddelbart under et 10 beholderåbningen lukkende dæksel anbragt en udstanset plade, der ligeledes dækker hele beholderåbningen, og som ved lukket dæksel ved indlægning af en ringtætning er forankret til beholaeråbningens kant, og hvis form i den centrale del afviger så meget fra dækslets form, 15 at der mellem disse to dele kan indsættes et luftfilter.A known oil container of the above-mentioned type (German publication specification No. 1 036 817) is provided immediately below a container opening closing cover, a punched plate which also covers the entire container opening and which, when closed cover by inserting a ring seal, is anchored to the container's container. and whose shape in the central portion differs so much from the shape of the cover that an air filter can be inserted between these two parts.
Samtidig tjener den udstansede plade herved som fastgørelsesorgan for filterpatronen, og hvor der mellem denne og en mod beholderåbningen vendende åbning af filterpatronens midterkanal lukkende holdeplade er an-20 bragt en trykfjeder, der dels trykker den udstansede plade mod dækslet og dels trykker filterpatronen med dens fra beholderåbningen bortvendende endeside mod det olietilføringen omsluttende sæde således på tættende måde, at der herved dannes en sikkerhedsventil. 1 2 3 4 5 6At the same time, the punched plate serves as a fastening means for the filter cartridge, and where a holding spring is provided between the and the opening channel of the filter cartridge which is closed towards the container opening, a pressure spring which first presses the punched plate against the cover and partly presses the filter cartridge off. the end face of the container opening towards the oil-enclosing seat in such a sealing manner as to form a safety valve. 1 2 3 4 5 6
Da luftfiltret såvel som oliefiltret skal være udskif 2 telige, kan dækslet og den udstansede plade ikke være 3 fast forbundet med hinanden. Derfor består den samle 4 de anordning af et antal enkeltdele, der ved udskift 5 ning af oliefiltret alle må skilles fra hinanden og 6 derpå atter sættes sammen. Også ved efterpåfyldning 2 150277 af olien vil der forekomme vanskeligheder, da til dette formål dækslet, luftfiltret, ringtætningen, den udstansede plade, trykfjederen og holdepladen må fjernes, når man vil tilføre olie til filterpatronens midterka-5 nal, hvilket alene er hensigtsmæssigt, da det uden om filterpatronen værende randområde er så smalt, så der ved forsøg på at påfylde olien her er stor fare for at spilde olie på holdepladen, hvor den vil samle sig i fordybningen for trykfjederen og derved gøre den næste 10 olieudskiftning til et overordentlig smudsigt arbejde.Since the air filter as well as the oil filter must be replace 2 times, the cover and the punched plate cannot be 3 firmly connected. Therefore, the assembly 4 consists of a plurality of individual parts which, when replacing 5 of the oil filter, must all be separated and 6 then reassembled. Also when refilling the oil, there will be difficulties as for this purpose the cover, air filter, ring seal, punched plate, compression spring and retaining plate must be removed when oil is added to the center channel of the filter cartridge, which is only appropriate, since the outside area of the filter cartridge is so narrow that when attempting to refill the oil here there is great danger of spilling oil on the holding plate, where it will accumulate in the recess of the compression spring and thereby make the next 10 oil change an extremely dirty job .
Det er opfindelsens formål at videreudforme en oliebeholder af ovennævnte art, således at udskiftning af oliefiltret såvel som efterpåfyldning af olie kan gennemføres væsentligt enklere og uden tilsmudsning.It is an object of the invention to further design an oil container of the above-mentioned type, so that replacement of the oil filter as well as replenishment of oil can be carried out substantially simpler and without soiling.
15 Dette opnås ifølge opfindelsen ved at udforme oliebeholderen på den i krav l’s kendetegnende del angivne måde.This is achieved according to the invention by designing the oil container in the manner specified in claim 1.
Herved kan for det første ved oliepåfyldningen dækslet ganske simpelt skrues af uden at ændre placeringen af 20 de øvrige Organer. Fastgørelsesdelen ifølge opfindelsen kan nemlig som følge af, at den dels er forankret i beholdermundingen uafhængig af dækslet og dels frigiver et tilstrækkelig stort område heraf til oliepåfyldning, forblive på sin plads under oliepåfyldningen og holder 25 herved over dødgangsforbindelsen og trykfjederen det i den første filteråbning indsatte lukkestykke uforanderlig fast, hvorved filterpatronen på fuldstændig aftæt-tet måde bliver presset mod det overfor beholderåbningen beliggende sæde.In the first place, the oil cap can simply be unscrewed without oil change without changing the position of the other organs. The fastening part according to the invention, because it is partly anchored in the container mouth independently of the cover and partly releases a sufficiently large area thereof for oil filling, remains in place during the oil filling and thus holds over the deadlock connection and the compression spring inserted into the first filter opening. closure is invariably fixed, whereby the filter cartridge is completely sealed against the seat opposite the container opening.
30 150277 330 150277 3
Dette gør ikke alene efterpåfyldningen af olie overordentlig enkel og renlig, men giver herudover den særlige fordel, at der opretholdes fuld adskillelse mellem den smudsige tilbageløbsolie indeholdende midterkanal 5 af filterpatronen og det friske henholdsvis filtrerede olie indeholdende rum, der omslutter filterpatronen, således at ingen tilsmudsning på filtret kan smutte forbi til den egentlige forrådsbeholder.Not only does this make the refilling of oil extremely simple and clean, but it also gives the special advantage of maintaining full separation between the dirty refill oil containing center channel 5 of the filter cartridge and the fresh and filtered oil containing compartments enclosing the filter cartridge, so that no soiling on the filter can slip past the actual storage container.
Skal filterpatronen udskiftes, kan dette ligeledes fore-10 gå på meget enkel måde ved, at man efter aftagning af dækslet løsner fastgørelsesindretningen og sammen med denne udtager filterpatronen fra oliebeholderen. Med en klud, der kastes bort, kan man ganske enkelt aftrække filterpatronen og bortkaste denne og derpå påsætte 15 en ny patron, der tilligemed fastgørelsesindretningen atter anbringes i oliebeholderen og bliver fastlåst her.If the filter cartridge is to be replaced, this can also be done in a very simple way by removing the fastening device after removing the cover and removing the filter cartridge from the oil container. With a cloth thrown away, one can simply pull off the filter cartridge and discard it and then attach a new cartridge which, in addition to the fastener, is again placed in the oil container and locked here.
Yderligere enkeltheder ved oliebeholderen ifølge opfindelsen vil fremgå af underkravene.Further details of the oil container according to the invention will be apparent from the subclaims.
Opfindelsen forklares nærmere i det følgende under hen-20 visning til tegningen, hvor fig. 1 viser et lodret snit gennem den væsentlige del af en udførelsesform for oliebeholderen med indsat filterpatron, fig. 2 viser samme del af oliebeholderen set ovenfra 25 og med aftaget dæksel, fig. 3 viser en enkelthed, delvis i snit efter en linie III-III i fig. 2, fig. 4 enkeltheder ved filterholderen i et aksialt længdesnit, til dels set fra siden, 30 150277 4 fig. 5 den i fig. 4 viste fastgørelsesindretning set fra oven, fig. 6 et snit efter en linie VI-VI i fig. 4, og fig. 7 centrerersoklen ved aftaget filterpatron set oven-5 fra i retning af pilen VII i fig. 1.The invention will be explained in more detail below with reference to the drawing, in which: FIG. 1 shows a vertical section through the essential part of an embodiment of the oil container with inserted filter cartridge; FIG. 2 is a top view of the same portion of the oil tank 25 and with the cover removed; FIG. 3 shows a simplicity, partly in section, along a line III-III in FIG. 2, FIG. 4 details of the filter holder in an axial longitudinal section, partially viewed from the side, FIG. 5 is the one shown in FIG. 4 is a top view of the fastener; FIG. 6 is a sectional view taken along line VI-VI of FIG. 4, and FIG. 7 is a top view of the centering base of the filter cartridge in the direction of arrow VII in FIG. First
En oliebeholder 2 er fremstillet af plast og har en olieudløbsstuds 4, en olieindløbsstuds 6 og en beholderåbning 8, der er omgivet af en oliepåfyldningsstuds 9·An oil container 2 is made of plastic and has an oil outlet nozzle 4, an oil inlet nozzle 6 and a container opening 8 surrounded by an oil filling nozzle 9 ·
Denne studs kan tillukkes tæt ved hjælp af et dæksel 12 10 med en ringtætning 14.This stud can be closed tightly by means of a cover 12 10 with a ring seal 14.
Pra bundvæggen 16 af oliebeholderen 2 rager en centreringssokkel 18 ind og danner en indre fortsættelse af olieindløbsstudsen 6. Soklen har en centreringskegle 20 og et ringsæde 22.The bottom wall 16 of the oil container 2 projects a centering socket 18 and forms an internal continuation of the oil inlet socket 6. The socket has a centering cone 20 and a ring seat 22.
15 Pilterpatronen 24 er hulcylindret og har en midterkanal 26, der ved begge ender står i forbindelse med yderrummet gennem en åbning, nemlig gennem en første filteråbning 28 og en anden filteråbning 30. Olien gennemstrømmer filterpatronen fra midterkanalen radialt udefter. 1 2 3 4 5 6 7 8 9 10 11The filter cartridge 24 is hollow cylindrical and has a center channel 26 which communicates at both ends with the outer space through an opening, namely through a first filter opening 28 and a second filter opening 30. The oil flows radially outward from the filter cartridge from the middle channel. 1 2 3 4 5 6 7 8 9 10 11
Pilterpatronen sidder med sin anden filteråbning 30 2 tætnende på ringsædet 22. Centreringskeglen 30 letter 3 påsætning af filterpatronen. Ringsædet 22 har en ring- 4 flade 27, der ligger an mod en endeflade 20 på filter 5 patronen, og en omtrent cylindrisk centreringsflade 31, 6 der er afbrudt af udstrømningskanaler 33 eller 33a med 7 et segmentagtigt, halvcirkulært eller et andet tvær 8 snit. Udstrømningskanalerne må ikke hindre centrerings 9 virkningen af centreringsfladen 31, men skal allerede 10 ved en lille opløftning af filterpatronen tillade en 11 udstrømning af olie, der fra midterkanalen 26 strømmer 150277 5 ’ gennem udstrømningskanalerne og derefter mellem fladerne 29 og 27 ind i oliebeholderens inderrum.The filter cartridge sits with its second filter opening 30 2 sealingly on the ring seat 22. Centering cone 30 facilitates 3 attachment of the filter cartridge. The ring seat 22 has an annular 4 surface 27 abutting an end surface 20 of the filter 5 cartridge, and a approximately cylindrical centering surface 31, 6 interrupted by outflow channels 33 or 33a with a segment-like, semicircular or other cross 8 section. . The outflow channels must not obstruct the centering effect of the centering surface 31, but should already allow a small outflow of the filter cartridge to allow an 11 outflow of oil flowing from the middle channel 26 through the outflow channels and then between the surfaces 29 and 27 into the inner space of the oil container.
I den første filteråbning 28 er der fra oven indtrykket en udbuet prop 32. Denne tjener til aftætning af den 5 første filteråbning og til fastholdelse af filterpatronen.In the first filter aperture 28, there is from the above impression an extended plug 32. This serves to seal the first filter aperture and to hold the filter cartridge.
På proppens 32 lukkeplade 34 er anbragt en indre, rørformet del 36 af en dødgangsforbindelse. Denne del er fremstillet i et stykke med proppen 32 og har ved sin øverste ende en yderflange 38, hvis yderflade indsnæv-10 res f.eks. i kegleform. . Ydervæggen på den indre rørformede del 36 har segmentagtige udsnit 40, fig. 4 og 6, der danner et oliegennemløb, for det tilfælde, at olie også bliver hældt ind i de rørformede dele.An inner tubular portion 36 of a dead-end connection is arranged on the closure plate 34 of the plug 32. This part is made integrally with the plug 32 and has at its upper end an outer flange 38, the outer surface of which narrows e.g. in cone shape. . The outer wall of the inner tubular portion 36 has segment-like sections 40; 4 and 6, which form an oil flow, in case oil is also poured into the tubular parts.
Den ydre rørformede del 42 har en inderflange 44 med 15 en inderflade, der indsnævrer sig, f.eks. en kegleflade. Delen er fremstillet i et stykke med en som fast'gørelsesdel 46 tjenende rigel. Riglen har et tværstykke 48, der er afstivet af en opretstående rippe 50.The outer tubular portion 42 has an inner flange 44 with an inner surface narrowing, e.g. a cone surface. The part is made in one piece with a bolt serving as a fastening part 46. The bolt has a crosspiece 48 which is supported by an upright rip 50.
Ribben 50 danner også et håndtag. Riglen har tillige 20 en midteråbning 52, der flugter med midteråbningen i den ydre rørformede del 42.The rib 50 also forms a handle. The bolt also has a center opening 52 which aligns with the center opening in the outer tubular portion 42.
Påfyldningsstudsen 9 for oliebeholderen (fig. 1-3) har på overfor hinanden liggende steder to segmentagtige fremspring 54, der indsnævrer fyldningsåbningen lidt, 25 og som på deres underside har hver en flad indgrebsudsparing 56 for enderne på riglens tværstykke 48.The oil reservoir filling nozzle 9 (Figs. 1-3) has two segment-like projections 54 opposite each other that slightly narrow the filling opening 25 and each have a flat engaging recess 56 for the ends of the cross member 48.
En trykfjeder 58 (fig. 1-4) støtter henholdsvis mod den nedre flade af tværstykket 48 og den øvre skulder 59 af proppens 32 lukkeplade 34.A compression spring 58 (Figures 1-4) rests respectively on the lower surface of the crosspiece 48 and the upper shoulder 59 of the closure plate 34 of the plug 32.

Hvis de rørformede dele 36 og 42 består af plast, kan de under forbigående henholdsvis indsnævring og udvidelse stikkes ind i hinanden, så at de i tilslutning hertil sidder fast i hinanden. Den i forvejen indsatte tryk-5 fjeder 58 stræber efter at presse de to dele ud fra hinanden hen til den af dødgangsforbindelsen 36,42 tilladte endestilling som vist i fig. 4.If the tubular portions 36 and 42 are made of plastic, they can be inserted into each other during transit and expansion, respectively, so that they are subsequently stuck together. The pre-inserted pressure spring 58 aims to push the two parts apart to the end position permitted by the dead-end connection 36, 42 as shown in FIG. 4th
Ved anvendelsen bliver proppen 32 trykket ind i filter-patronens 24 øverste (første) åbning. Til dette formål 10 kan man nedefra trykke filterpatronen mod proppen.In use, the stopper 32 is pressed into the top (first) opening of the filter cartridge 24. For this purpose 10, the filter cartridge can be pressed downwards from the plug.
Trykfjederen 58 bliver først sammentrykket. Efter at lukkepladen.34 på proppen er nået hen til ringflangen 44, fremkommer en stiv trykforbindelse, der gør det muligt at drive proppen 32 ind i den første filteråb-15 ning. Proppen fastholder så filterpatronen pålideligt og tætner den første filteråbning.The compression spring 58 is first compressed. After the closure plate.34 of the plug has reached the annular flange 44, a rigid pressure connection is obtained which allows the stopper 32 to be driven into the first filter opening. The plug then securely holds the filter cartridge and seals the first filter opening.
Derefter bliver den i riglen 46 hængende filterpatron ført ind gennem åbningen 8 i oliebeholderen 2 og med sin anden filteråbning sat an mod centreringskeglen 20.Then, the filter cartridge hanging in line 46 is inserted through the opening 8 in the oil container 2 and with its second filter opening is applied to the centering cone 20.
20 Riglen bliver fastlåst i åbningen ved, at riglens ender nedefra griber ind i indgrebsudsparingerne 56. Trykfjederen 58 holder ved tryk nedefra riglen sikkert i disse indgrebsudsparinger og trykker tillige filterpatronen mod ringfladen 27, hvorved der opnås den øn-25 skede sikringsventilvirkning.The latch is locked in the opening by the bottom ends of the latch engaging the engagement recesses 56. The compression spring 58 securely pressurizes the latch into these engagement recesses and also presses the filter cartridge against the ring surface 27, thereby obtaining the desired safety valve action.
Olietrykket i midterkanalen '26 virker på den nederste flade af lukkepladen 34. Trykfjederen 58 er dimensioneret således, at den lader filterpatronen løfte sig fra sit sæde, når trykket overskrider en maksimal til-30 ladelig værdi.The oil pressure in the center duct '26 acts on the lower surface of the closure plate 34. The compression spring 58 is sized to allow the filter cartridge to lift from its seat when the pressure exceeds a maximum allowable value.
