Den foreliggende opfindelse angâr en motorkompressor af den i krav l's indledning angivne art.The present invention relates to a motor compressor of the kind specified in the preamble of claim 1.
I kolekompressorer, som anvender et stempel-cylinder-arrangement til kompression, bliver det luftformige kole-5 middel varmtunder kompressionen og afgiver varmeenergi til cylinder og cylinderhoved, sâledes at cylinderens og cylin-derhovedets temperatur stiger. De hoje temperaturer kan med-fore, at smcremiddel koger og mister de smorende egenskaber. Dette kan i sidste instans medfore aflejring af kul pâ ven-10 tiler, ventilsæder, klapper og lignende. Den stadige akkumu- lering af sâdanne aflejringer vil til sidst hindre ventilar-rangementets funktion, sâledes at kompressoren mâ standses og defekte dele udskiftes.In coal compressors which use a piston-cylinder arrangement for compression, the gaseous carbon is heated during compression and provides thermal energy to the cylinder and cylinder head, thus increasing the temperature of the cylinder and cylinder head. The high temperatures can cause lubricant to boil and lose the lubricating properties. This may ultimately lead to the deposition of coal on valves, valve seats, flaps and the like. The constant accumulation of such deposits will eventually hinder the functioning of the valve arrangement, so that the compressor must be stopped and defective parts replaced.
Generelt er koling af cylinderhovedet overladt til det 15 kolemiddel, som suges ind i kompressoren. Selv hvor dette var tilstrækkeligt til en acceptabel koling af cylinderhovedet, ville en storre kompressorvirkningsgrad kunne opnâs, hvis cylinderhovedet blev yderligere kolet.Generally, coal of the cylinder head is left to the coolant which is sucked into the compressor. Even where this is sufficient for acceptable cooling of the cylinder head, a greater compressor efficiency could be achieved if the cylinder head were further coal.
Fra beskrivelsen til US patent nr. 2.215.645 kendes en 20 motorkompressor, hvor et kort ror strækker sig opad fra top- âbningen pâ oliepassagen i krumtapakslen og tjener til at udsprojte olie over topfladerne af kompressorkomponenterne.From the specification of US Patent No. 2,215,645, a motor compressor is known in which a short pipe extends upwards from the top opening of the oil passage in the crankshaft and serves to spray oil over the top surfaces of the compressor components.
For at sikre, at noget af olien vil falde pâ de ydre flader af stempel og cylinder for at smore disse, er en ledeplade 25 forhundet til toppen af cylinderen for at afboje noget af den udsprojtede olie, sâledes at denne kan dryppe ned pâ den ydre overflade af stemplet. Det er indlysende, at den væsentlige del af den olie, som udsprojtes over ledepladen, rammer kompressorhuset og vender tilbage til oliesumpen i 30 bunden af kompressoren. Det skal bemærkes, at ledepladen i henhold til den nævnte patentbeskrivelse er anbragt pâ den aksialt inderste del af cylinderen for at sikre afboj-ning af olie til smoring af stemplet.To ensure that some of the oil will fall on the outer faces of the piston and cylinder to lubricate them, a baffle 25 is prepped to the top of the cylinder to deflect some of the ejected oil so that it can drip onto the outer surface of the piston. It is obvious that the essential part of the oil ejected over the baffle plate hits the compressor housing and returns to the oil sump at the bottom of the compressor. It should be noted that, according to the aforementioned patent specification, the baffle is located on the axially inner part of the cylinder to ensure deflection of oil for lubrication of the piston.
Det er endvidere kendt at forsyne cylinderhovedet med 35 koleribber. Sâdanne koleribber har vist sig effektive i varierende grad til at sænke cylinderhovedets temperatur, men yderligere temperatursænkning er onskelig for at oge komDressorens virkninasarad. hindrp kulafleirina i ventil- 2Furthermore, it is known to provide the cylinder head with 35 carbon ribs. Such carbon ribs have proven to be effective to varying degrees in lowering the cylinder head, but further lowering of temperature is desirable to increase the compressor's range of operation. obstruct the ball bearings in valve 2

En mâde at holde afga'ngsventiltemperaturen lav nok til at hindre akkumulering af kulaflejringer er at bortlede 5 varmeenergi fra cylinderhovedet hurtigt. Ved den foreliggen- de opfindelse foretages denne varmebortledning ved at bade cylinderhovedet i en strom af olie.One way to keep the outlet valve temperature low enough to prevent the accumulation of carbon deposits is to quickly dissipate 5 heat energy from the cylinder head. In the present invention, this heat dissipation is effected by bathing the cylinder head in a stream of oil.
Ifolge den foreliggende opfindelse imodegâs ovennævnte problem med ekstremt hoje cylinderhovedtemperaturer ved, ^0 at kompressoren. udformes som angivet i krav 1.According to the present invention, the above-mentioned problem of extremely high cylinder head temperatures is counteracted by the compressor. is designed as claimed in claim 1.
Ved krumtapakslens rotation vil en del af det smore-middel, som pumpes op gennem roret, blive slynget i det væ-sentlige radiait ud gennem mundingen, og, nâr den rammer prelpladen pâ cylinderhovedet, blive afbojet af denne, sâ-35 ledes at det strommer ned over side- og endeyderflader pâ cylinderhovedet og derved bortlede varme fra dette.Upon rotation of the crankshaft, a portion of the lubricant pumped up through the rudder will be thrown out in the essential radius through the mouth and, when it hits the baffle plate on the cylinder head, will be deflected by it. flows down the side and end face surfaces of the cylinder head, thereby dissipating heat from it.
Opfindelsen skal i det folgende forklares naermere i forbindelse med tegningen, hvor fig. 1 viser et snit langs linien 1-1 i fig. 2 gennem 20 en kolekompressor, fig. 2 kompressoren set fra oven og delvis gennemskâret, fig. 3 den overste del af kompressoren set fra venstre i fig. 1 og delvis gennemskâret, fig. 4 kompressorens cylinderhoved, 25 fig. 5 et snit langs linien 5-5 i fig. 4, og fig. 6 set fra siden et olieror, som er anbragt i en oliepassage i kompressorens kridmtapaksel.The invention will now be explained in more detail in connection with the drawing, in which 1 is a sectional view taken along line 1-1 of FIG. 2 through 20 a carbon compressor; FIG. Figure 2 is a top view of the compressor and partially cut through; 3 shows the upper part of the compressor as seen from the left in FIG. 1 and partially cut through; FIG. 4, the cylinder head of the compressor; FIG. 5 is a section along line 5-5 of FIG. 4, and FIG. 6 is a side view of an oil rudder disposed in an oil passage in the compressor shaft shaft.
Fig. 1 viser en konventionel kompressor 8 med en nedre kapsel 10 og en ovre kapsel 12, som kan være svejst eller 30 loddet sammen langs en som 14. I kompressoren 8 er monteret et krumtaphus 16 med en roterbart lejret krumtapaksel 18 og en motor 20 omfattende en rotor 22, der er fastgjort til krumtapakslen 18, og en stator 44 med feltviklinger 26.FIG. 1 shows a conventional compressor 8 with a lower capsule 10 and an upper capsule 12 which can be welded or soldered together along one as 14. In the compressor 8 is mounted a crankcase 16 with a rotatably mounted crankshaft 18 and a motor 20 comprising a rotor 22 attached to crankshaft 18 and a stator 44 with field windings 26.

optaget i en cylinder 38 i krumtaphuset 16. Til cylinderen 38 er forbundet en pakning 40, en klap 42, en ventilplade 44, en pakning 46 og et cylinderhoved 48 ved hjælp af fire boite 50. Stempel-cylinderarrangementet er dynamisk afbalan-5 ceret ved hjælp af en modvægt 52, soin er fastgjort til krum-tapakslen 18.accommodated in a cylinder 38 in the crankcase 16. To the cylinder 38 are connected a gasket 40, a flap 42, a valve plate 44, a gasket 46, and a cylinder head 48 by means of four members 50. The piston-cylinder arrangement is dynamically balanced by by means of a counterweight 52, soin is attached to the crank-tap shaft 18.
I den nedre kapsel 10 er, saramen med kolemiddelror 54, anbragt en oliepumpe 56, soin er forbundet til den nederste ende af krumtapakslen 18 i en oliesump 58. Gennem krumtap-10 akslen 18 strækker sig en aksial oliepassage 60 og en 0vre oliepassage 62, som leverer olie til smoring af sàdanne om-râder som et hovedleje 64 og et trykleje 66.In the lower capsule 10, an oil pump 56 saramen is disposed in the sump frame, which is connected to the lower end of the crankshaft 18 in an oil sump 58. Through the crankshaft 18, an axial oil passage 60 and an upper oil passage 62 extend. which supplies oil for lubricating such areas as a main bearing 64 and a pressure bearing 66.
ünder kompressorens drift optræder der meget h0je tem-peraturer i kompressorens indre med det résultat, at kompo-15 nenterne, eksempelvis motoren 20, krumtaphusets leje 64, krumtapaksellejet 66 og især cylinderhovedet 48 bliver eks-tremt varme og kræver koling.During operation of the compressor, very high temperatures occur in the interior of the compressor, with the result that the components, such as the engine 20, crankcase bearing 64, crankshaft bearing 66 and in particular cylinder head 48, require extremely heat.
Generelt opnâs kolingen af ovennævnte komponenter ved, at oliepumpen 56 pumper olie fra sumpen 58 op gennem olie-20 passagen 60 ikke kun til smorepunkter, men ogsâ for at lede varmeenergi fra motoren 20, lejerne 64,66 og andre dele forbundet med eller placeret nær krumtapakslen 18. Nâr den opad-gâende bevægelse gennem oliepassagen 60 eller den ovre oliepassage 62 ophorer, vender olien tilbage til oliesumpen 58 25 med meget hoj temperatur og kan, medmindre den koles passende, miste sine smorende egenskaber. Dette kan medfore tidligere funktioneringsfejl.In general, the coaling of the above components is achieved by the oil pump 56 pumping oil from the sump 58 up through the oil passage 60 not only to lubrication points, but also to conduct heat energy from the engine 20, bearings 64.66 and other parts associated with or located near crankshaft 18. When the upward movement through the oil passage 60 or the upper oil passage 62 ceases, the oil returns to the oil sump 58 25 at a very high temperature and, unless properly cooled, may lose its lubricating properties. This may cause previous malfunctions.
En hensigtsmæssig koling af olien opnâs ved hjælp af et olieslyngerèr 68, som er anbragt i âbningen 63 fra den 30 ovre oliepassage 62 i toppen af krumtapakslen 18. Ifolge den viste udforelsesform er slyngeroret 68 vinkelforskudt i forhold til krumtapakslens 18 orndrejningsakse. Slyngero-ret 68 har en forudbestemt længde af ârsager, som senere vil blive omtalt, og dets overste âbning 70 ligger længere 35 fra orndrejningsaksen end dele af krumtapakslen 18.Appropriate cooling of the oil is obtained by means of an oil sling 68 located in the opening 63 of the 30 upper oil passage 62 at the top of the crankshaft 18. According to the embodiment shown, the sling tube 68 is angularly displaced relative to the crankshaft 18's rotational axis. The sling tube 68 has a predetermined length of causes which will be discussed later, and its upper opening 70 is further 35 from the rotary shaft than portions of the crankshaft 18.

4 blive tvunget op geimem slyngeroret 68 og slynget i det væsentlige opad - radiait udad fra dettes âbning 70 mod fladerne 73 i den ovre kapsel 12. Da bâde den nedre kapsel 10 og den ovre kapsel 12 er koldere end olien, vil varme-5 energi blive overfort fra olien til kapslerne 10,12, hvor- for olien koîes under vejs til oliepumpen 58. For at sikre, at den fra roret 68 udslyngede olie ikke ranimer den overste flade 75 i den ovre kapsel 12 - hvorfra olien ville dryppe ned pâ kompressorkomponenter - er slyngeroret 68 fremstil-2^0 let af stift materiale og skrâtstillet i forhold til lodret, sâledes at oliestrommen ledes bort fra den overste kapsel-flade 75 og mod sidefladerne 73. Er visse komponenter pla-ceret hojere end toppen af krumtapakslen 18, sâledes som det er tilfældet ved den i fig. 1 viste udformning, skal slynge-15 roret 68 hâve en sâdan forudbestemt længde, som sikrer, at rorâbningen 70 ligger hojere end sâdanne dele, for at disse ikke skal komme i vejen for den udslyngede olie.4 is forced upwardly by the sling tube 68 and substantially wound upwardly - radially outwardly from its opening 70 toward the surfaces 73 of the upper capsule 12. As both the lower capsule 10 and the upper capsule 12 are colder than the oil, heat-5 energy will be transferred from the oil to the capsules 10,12, whereupon the oil is cooled en route to the oil pump 58. To ensure that the oil discharged from the tube 68 does not run over the top surface 75 of the upper capsule 12 - from which the oil would drip onto the Compressor Components - The sling tube 68 is made of rigid material and sloped with respect to the vertical, so that the oil stream is directed away from the upper capsule surface 75 and toward the side surfaces 73. Some components are placed higher than the top of the crankshaft 18 , as is the case with the one shown in FIG. 1, the sling tube 68 must have such a predetermined length which ensures that the tube opening 70 is higher than such parts so that they do not get in the way of the ejected oil.
Slyngeroret 68 er altsâ, takket være sin skrâ stilling i forhold til krumtapakslens 18 omdrejningsakse og âbningens 20 70 afstand fra denne, i stand til at slynge olie mod side fladerne i den ovre kapsel 12. Slyngeroret 68 kan endvidere bukkes for tilpasning til forskellige kompressormodeller.Thus, thanks to its oblique position relative to the axis of rotation of the crankshaft 18 and the distance from the opening 20 of the crank shaft 68, the sling tube 68 is able to flush oil against the surfaces of the upper capsule 12. The sling tube 68 can also be bent for adaptation to various compressor models.
Det er tidligere nævnt, at cylinderhovedet 48 udsættes for ekstremt hoje temperaturer under kompressorens 8 drift.It has been mentioned previously that the cylinder head 48 is subjected to extremely high temperatures during the operation of the compressor 8.
25 Dette skyldes forst og fremmest den temperatur, som hersker i kompressorens indre, og den varmeudvikling, som er forbun-det med sammentrykningen af kolemidlet ved hjælp af stemplet i cylinderen 38. Til nedsættelse af denne temperatur kan cylinderhovedet 48 være forsynet med et antal varmeafleden-30 de finner 78. Trods disse finner kan cylinderhovedets 48 temperatur alligevel være for hoj under kompressorens drift.This is primarily due to the temperature prevailing in the interior of the compressor and the heat generation associated with the compression of the coolant by means of the plunger in the cylinder 38. To reduce this temperature, the cylinder head 48 may be provided with a plurality of heat dissipation. -30 they find 78. Despite these finds, the temperature of the cylinder head 48 may nevertheless be too high during the operation of the compressor.
For at nedsætte cylinderhovedets 48 temperatur har slyngeroret 68 huiler 80,81 i sidevæggen, af hvilke det ene hul 80 er rettet radiait ud fra omdrejningsaksen. Under 35 slyngerorets 68 rotation med krumtapakslen 18 vil det nævnte hul 80 altid vende mod kapslens 12 sideflader 73. En del af den olie, som ledes op gennem slyngeroret 68, vil blive slynget i det væsentlige vandret, radiait ud gennem hullet 5To lower the temperature of the cylinder head 48, the sling tube 68 has 80,81 holes in the side wall, of which one hole 80 is directed radially from the axis of rotation. During rotation of the sling tube 68 with the crankshaft 18, the said hole 80 will always face the side faces 73 of the capsule 12. A portion of the oil which is led up through the sling tube 68 will be thrown substantially horizontally, radiating out through the hole 5.

80. Nâr slyngeraret 68 roterer forbi cylinderhovedet 48, vil oliestrommen fra hullet 80 ranime cylinderhovedet og kole dette. Olie slynges ogsâ ud gennem det andet hul 81, men da dette er vendt mod omdrejningsaksen, er oliemængden ringe.80. As the winding 68 rotates past the cylinder head 48, the oil stream from the hole 80 will run the cylinder head and cool it. Oil is also thrown out through the second hole 81, but as this is facing the axis of rotation, the amount of oil is low.
5 At der findes to huiler 80,81 i slyngerorets sidevæg, skyl- des alene en fabrikationsmæssig lettelse.5 The fact that two weights 80,81 are found in the side wall of the sling tube is due solely to a fabrication relief.
For at sikre, at en del af den olie, som udslynges fra hullet &ô* s tr cramer ud over enden 49 af cylinderhovedet 48 og finnerne 7S pâ dette, er en prelplade 82, der ogsâ tje-10 ner som varmeafledende flade og er forsynet med slidser 84, anbragt pâ tværs pâ cylinderhovedets 48 topflade. Olie fra hullet 80 ranimer prelpladen 82 og strcmmer fra denne ud over cylinderhovedets 48 overflader nær ventilpladen 44, medens samtidig en del af olien passerer slidserne 84 og strcmmer 15 ned over cylinderhovedets 48 ende 49 og finnerne 78.To ensure that a portion of the oil discharged from the hole & trams beyond the end 49 of the cylinder head 48 and the fins 7S thereon is a baffle plate 82 which also serves as a heat dissipating surface and is provided. with slots 84 arranged transversely on the top surface of the cylinder head 48. Oil from the hole 80 rims the baffle 82 and flows therefrom beyond the surfaces of the cylinder head 48 near the valve plate 44, while at the same time a portion of the oil passes through the slots 84 and flows 15 down the end 49 of the cylinder head 48 and the fins 78.
Som vist i fig. 1 og 5 er prelpladen 82 anbragt tvær-stillet pâ topfladen af cylinderhovedet 48 nær pakningen 46. Prelpladen 82 kan anbringes pâ topfladen nær enden 49, men pâ grund af de pladsforhold, som sædvanligvis hersker mel-20 lem cylinderhoved 48 og den cvre kapsel 12, har det i prak- sis vist sig, at prelpladen 82 udcver sin cnskede funktion mest effektivt, nâr den er anbragt ved pakningen 46. End-videre har prelpladen 82 en sâdan hojde og afstand fra kap-s.l.en 10, at sædvanlige fremstillingstolerancer kan benyttes.As shown in FIG. 1 and 5, the baffle plate 82 is disposed transversely on the top surface of the cylinder head 48 near the gasket 46. The baffle plate 82 can be placed on the top surface near the end 49, but due to the space conditions usually prevailing between cylinder head 48 and the outer capsule 12. , it has been found in practice that the baffle plate 82 performs its desired function most effectively when placed at the gasket 46. Furthermore, the baffle plate 82 has such a height and distance from the cap 10 that conventional manufacturing tolerances can used.
