Description
i 149902 5 Opfindelsen angår en omstyrbar dieselforbrændingsmo tor, især til skibsfremdrift, med en kamaksel bestående af flere ens kamaksel-afsnit, som hver styrer to brændstofpumper og to ventiler, hvorhos kamakslen i afhængighed af krumtapakslens omdrejningsretning 10 er drejelig i begge omdrejningsretninger og hvorhos yderligere i det mindste brændstofpumpeknasternes stilling i forhold til krumtapakslen ved hjælp af en omstyringsindretning er omstyrbar mellem en stilling for den ene omdrejningsretning og en stilling 15 for den anden omdrejningsretning.This invention relates to a steerable diesel combustion engine, particularly for ship propulsion, with a camshaft consisting of several identical camshaft sections, each controlling two fuel pumps and two valves, the camshaft depending on the shaft rotation direction 10 being rotatable in both directions of rotation. at least the position of the fuel pump cutters relative to the crankshaft by means of a steering device is reversible between a position for one direction of rotation and a position 15 for the other direction of rotation.
Det er - fx fra CH-PS 552133 - kendt, at styre brændstof indsprøjtningen i en forbrændingsmotor eller i en motor af ovennævnte art ved hjælp af en med 20 knaster forsynet kamaksel, som på sin side er forbundet med krumtapakslen, og som drives af denne. Ved motorer, som er udrustet med ventiler, er der på denne kamaksel samtidig anbragt yderligere knaster til styring af disse ventiler, fx udstødningsventi-25 lerne. For at nå samme driftvilkår under fremad-og bak- drejeretningen i en omstyrbar forbrændingsmotor med hensyn til brændstofindsprøjtningen, omstyres kamakslen på kendt måde i forhold til krumtapakslen, d.v.s. ved skiftet fra en omdrejningsretning på 30 motoren til den modsatte drejes kamakselen i en vis vinkel i forhold til krumtapakselen ved hjælp af en omstyringsindretning. Fordi man med omstyringsindretningen derved drejer hele kamakslen er, under bakomdrejningsretningen, styretiderne ikke mere 149902 2 1 optimale for ventilerne; det medfører at motorens driftsforhold under bakretningsrotation er stærkt forringede.It is known, for example from CH-PS 552133, to control the fuel injection in an internal combustion engine or an engine of the above-mentioned type by means of a camshaft provided with 20 camshafts, which in turn are connected to the crankshaft and are driven by it. . In the case of motors equipped with valves, additional camshafts are provided on this camshaft for controlling these valves, for example the exhaust valves. In order to achieve the same operating conditions under the forward and reverse direction in a reversible combustion engine with respect to the fuel injection, the camshaft is known in the known manner relative to the crankshaft, i.e. when changing from a direction of rotation of the engine to the opposite, the camshaft is rotated at a certain angle to the crankshaft by means of a steering device. Because, with the steering device thereby turning the entire camshaft, under the reverse direction, the control times are no longer optimal for the valves; this causes the engine operating conditions during reverse direction to be greatly degraded.
5 Det er derfor opfindelsens formål at fremskaffe en kamaksel, hvormed man trods omstyringen af knasterne til brsends tof indsprøjtningen ikke forandrer de samtidigt på denne kamaksel siddende styreknaster for udstødningsventilerne med hensyn til disses 10 vinkelstilling i forhold til krumtapakslen. Dette mål nås ifølge opfindelsen på den måde, at de knaster, der betjener brændstofpumperne, er drejelige mellem anslag, og de knaster, der betjener ventilerne på kendt måde, er anbragt fast på kamakslen, at 15 yderligere kamakslen selv ikke er omstyrbar i forhold til krumtapakslen, og at endelig et antal omstyringsindretninger kun aktivt omstyrer knasterne til brændstofpumperne.It is therefore the object of the invention to provide a camshaft which, despite the steering of the camshafts for the fuel injection, does not alter the simultaneous control knobs on this camshaft for the exhaust valves with respect to their angular position with respect to the crankshaft. This object is achieved according to the invention in that the camshafts operating the fuel pumps are rotatable between stops and the camshafts operating the valves in a known manner are fixed to the camshaft, that the additional camshaft itself is not controllable relative to the camshaft itself. the crankshaft, and that finally a number of steering devices only actively redirect the fuel pump bosses.
20 Den nye kamaksel selv omstyres ikke; den har derfor under begge omdrejningsretninger en uforandret fasestilling i forhold til krumtapakslen. Denne konstante fasestilling i forhold til krumtapakslen under begge omdrejningsretninger bibeholdes dermed også for 25 de, som også hidtil sædvanligt, fast på kamakslen siddende knaster til styringen af ventilerne. Deres styretider er derfor optimal under begge omdrejningsretninger .20 The new camshaft itself is not overturned; it therefore has an unchanged phase position in both directions with respect to the crankshaft. This constant phase position with respect to the crankshaft under both directions of rotation is thus also retained for those which, even so far as usual, are fixed to the camshaft locks for the control of the valves. Their control times are therefore optimal under both directions of rotation.
30 Ved den nye kamaksel virker omstyringsindretningen alene på de nu drejeligt på kamakslen anordnede styreknaster til drift af brændstofpumperne; disse knaster bliver - som tidligere hele kamakslen - ved overgang fra en omdrejningsretning til den anden 149902 3 1 ved hjælp af olietrykket i en hydraulisk omstyrings-indretning drejet en fast vinkel i forhold til krumtapakslen - og dermed i den nye konstruktion i forhold til kamakslen.30 At the new camshaft, the steering device operates solely on the now pivotally mounted control shafts for operating the fuel pumps; as previously the entire camshaft, these camshafts are rotated at a fixed angle to the crankshaft by a change of direction from one direction to the other by means of the oil pressure in a hydraulic steering device, and thus in the new construction relative to the camshaft.

Yderligere er det hensigtsmæssigt at montere styreknasterne til betjening af brændstofpumperne fast på en bøsning, som på sin side er drejelig i forhold til kamakslen. Denne detalje medfører den fordel, 10 at styreknasten for den enkelte brændstofpumpe individuelt kan justeres.Further, it is convenient to mount the control knobs for operating the fuel pumps to a bushing which in turn is rotatable relative to the camshaft. This detail has the advantage that the control box for the individual fuel pump can be adjusted individually.
En konstruktiv enkel og fordelagtig løsning til omstyringen af styreknasterne for brændstofindsprøjt-15 ningen opnår man, når hver to styreknaster hhv. deres bøsninger til betjening af to cylindres brændstofpumper parvis danner ringformede trykkamre i en hydraulisk omstyringsindretning, hvilke trykkamre, med en diametralt modsat placerede anslagsvinger 20 udformet på styreakslen fastsiddende ring, er adskilte fra hinanden.A constructively simple and advantageous solution for the control of the fuel injection control knobs is obtained when every two control knobs respectively. their bushings for operating two-cylinder fuel pumps in pairs form annular pressure chambers in a hydraulic steering device, which pressure chambers, with a diametrically opposite abutment wings 20 formed on the steering shaft ring, are spaced apart.
Den nye konstruktion udviser udover de optimale styretider for ventilerne ved begge omdrejningsret-25 ninger for motoren også yderligere fordele; således bliver omstyringstiden kortere, fordi mindre oliekamre skal fyldes med olie, eller - med uændret omstyringstid - kan kapaciteten for styreoliepumpen reduceres. Yderligere kan knasterne - i modsætning til 30 de hidtil kendte konstruktioner, i hvilke styreknasterne for ventilerne og brændstofpumpen er forenede på én kamaksel - konstrueres med positive løft.In addition to the optimum control times for the valves at both directions of rotation of the engine, the new design also offers additional advantages; thus, the steering time becomes shorter because smaller oil chambers need to be filled with oil or - with unchanged steering time - the capacity of the steering oil pump can be reduced. Further, unlike the previously known designs in which the valves of the valves and fuel pump are united on one camshaft, the lugs can be constructed with positive lifting.
Der kan derfor under brændstofpumpestemplets nedadgående slag opnås tilstrækkelig tid til, at pumpekamme- 4 140902 i ret kan fyldes med brændstof. Endelig kan de relativt store drejningsmomenter, som forårsages af brændstofindsprøjtningen - som ved den i indledningen nævnte konstruktion - mekanisk overføres til de på kamakslen 5 fastsiddende ringe gennem knasternes hhv. knastbøsningernes anlæg mod disse ringes anlægsvinger; ved hjælp af olietrykket i den hydrauliske omstyringsindretning må man så hele tiden sikre sig, at knasterne hhv. knastbøsningerne konstant ligger an mod vinger-10 ne, også såfremt der optræder torsionssvingninger i kamakslen.Therefore, during the downward stroke of the fuel pump piston, sufficient time can be obtained for the pump chamber 4 to be properly filled with fuel. Finally, the relatively large torques caused by the fuel injection - as in the construction mentioned in the preamble - can be mechanically transferred to the rings fixed on the camshaft 5 through the lugs, respectively. the abutment of the cam bushes against the abutment wings of these rings; By means of the oil pressure in the hydraulic steering device, it is then always necessary to make sure that the lugs and the hydraulic actuator are mounted. the cam bushes constantly engage the wings 10 even if torsional oscillations occur in the camshaft.
Nedenfor belyses opfindelsen nærmere i forbindelse med et udførelseseksempel.The invention is further illustrated below in connection with an exemplary embodiment.
15 fig. 1 viser et udsnit af en sideprojektion af en totakts dieselmotor, som illustrerer et pumpehus, kamakslen med omstyringsindretningen hhv. brændstof-20 pumperne og de hydrauliske løftepumper for udstødningsventilerne i to cylindre i motoren.FIG. 1 is a sectional side view of a two-stroke diesel engine illustrating a pump housing, camshaft with the steering device, respectively. the fuel-20 pumps and hydraulic lift pumps for the two-cylinder exhaust valves in the engine.
fig. 2 viser en kamaksel ifølge opfindelsen, 25 hvor de enkelte, mod hinanden og i hinanden liggende elementer er trukket ud fra hverandre; fig. 3 er slutteligt en variant af den detalje 30 i kamakslen ifølge fig. 2.FIG. 2 shows a camshaft according to the invention, wherein the individual, opposed and adjacent elements are pulled apart; FIG. 3 is finally a variant of the detail 30 of the camshaft of FIG. 2nd
På en konsol 1 (fig. 1), som sidder på siden af en ikke nærmere vist dieselmotor, står et pumpehus 3 fastgjort med skruer 2; dette rummer i sin nedre 149902 5 1 del, hvis dæksel er fjernet, en kamaksel 4 til drift af to brændstofpumper 6 og to ventilløftepumper 7 til hydraulisk åbning og lukning af udstødningsventilerne på to cylindre i motoren.On a bracket 1 (Fig. 1), which sits on the side of a diesel engine not shown, a pump housing 3 is fixed with screws 2; this holds in its lower part, the cover of which is removed, a camshaft 4 for operating two fuel pumps 6 and two valve lift pumps 7 for hydraulically opening and closing the exhaust valves on two cylinders in the engine.
5 I overensstemmelse hermed bærer kamakslen 4 med en til hver af de tilhørende cylindre - en i et i forhold til et vertikalt midterplan spejlsymmetrisk arrangement - en fast på akslen siddende styreknast 10 8, som over en rulle 9 styrer et drivstempel 10 til åbning og lukning af udstødningsventilen.Accordingly, the camshaft 4, with one of each of the associated cylinders - one in a mirror-symmetrical arrangement relative to a vertical center plane - carries a fixed control shaft 10 8 which, over a roller 9, controls a drive piston 10 for opening and closing. of the exhaust valve.
Regnet fra styreknasten 8 og ind mod pumpehusets 3 underdel følger kamakslens 4 leje 11, som er an-15 bragt bagved knastbøsningerne 12, som ifølge nærværende opfindelse er monteret drejeligt på kamakslen 4.From the control box 8 and towards the lower part of the pump housing 3, follow the bearing 11 of the camshaft 4, which is arranged behind the cam bushes 12, which according to the present invention are pivotally mounted on the camshaft 4.
På de omstyrbare bøsninger 12 ifølge opfindelsen 20 er brændstofpumpeknasterne 13 til styring af brændstofpumperne 6 fastgjort; forbindelsen mellem brændstofpumpeknasterne 13 og pumperne 6 sker via ruller 9 og ikke viste drivstempler.On the controllable bushings 12 of the invention 20, the fuel pump lugs 13 for controlling the fuel pumps 6 are secured; the connection between the fuel pump knobs 13 and the pumps 6 takes place via rollers 9 and drive pistons not shown.
25 Mellem de to brændstofpumpeknaster 13 findes en hydraulisk omstyringsindretning 14, som over ledninger 15 og 16 er tilsluttet et ikke vist styreolie-kredsløb. Med omstyringsindretningen 14 omstyres de to brændstofpumpeknaster 13.25 Between the two fuel pump knobs 13 is a hydraulic steering device 14, which is connected via lines 15 and 16 to a control oil circuit not shown. With the control device 14, the two fuel pump knobs 13 are redirected.

Over pumpehuset 3 hvorpå løftepumperne 7 direkte og brændstof pumperne 6 via et mellemstykke 5 er-fastgjort, findes en horisontal, parallel med kamakslen 4 forløbende reguleringsaksel 17, med hvis hjælp 6 169902 1 de per slag af braendstofpumperne 6 værende brændstof-mængder kan reguleres.Above the pump housing 3, to which the lifting pumps 7 are directly mounted and the fuel pumps 6 via an intermediate piece 5, there is a horizontal control shaft 17 extending parallel to the camshaft 4, with the aid of which the fuel quantities per stroke of the fuel pumps 6 can be controlled.
Brændstofpumperne 6 sidder i et fælles brændstofpum-5 pehus 18, hvorfra brændstofledningerne 19 fører op og til indsprøjtningsventilerne, medens styreolie-ledninger 20 forbinder ventilløftepumperne 7 med servomotorer til åbning og lukning af udstødningsventi lerne.The fuel pumps 6 are located in a common fuel pump housing 18, from which the fuel lines 19 lead up and to the injection valves, while control oil lines 20 connect the valve lift pumps 7 with servomotors for opening and closing the exhaust valves.

Som fig. 2 viser bærer kamakslen 4 i midten, d.v.s. i det indre af omstyrings indretningen 14, en ring 21, som på to i forhold til hinanden diametralt modsat liggende steder på sin omkreds har udformet 15 vingeagtige anslag 22. Ringen 21 er i fig. 1 i en senere proces påkrympet på akslen og fast forbundet med denne; den kan dog også - som vist i fig. 3 - være udformet i et stykke med kamakslen 4', i ringen 23 er indsat anslagsvinger 24 som holdes fast med 20 skruer 25.As FIG. 2 shows the carrier camshaft 4 in the middle, i.e. in the interior of the steering device 14, a ring 21 which, at two diametrically opposite locations on its perimeter, has 15 wing-shaped abutments 22. The ring 21 is shown in FIG. 1 in a later process shrunk on the shaft and firmly connected thereto; however, as shown in FIG. 3 - be formed integrally with the camshaft 4 ', in the ring 23 are inserted impact vanes 24 which are retained by 20 screws 25.
Fra begge sider er i monteret tilstand de ifølge opfindelsen på kamakslen 4 drejeligt lejrede knastbøsninger 12 skubbet ind over ringen 21 med sine 25 ligeledes diametralt overfor hinanden liggende, indad fremspringende anslag 26. De bliver forbundet med hinanden gennem disse anslag 26 ved hjælp af skruer. På denne måde opstår der mellem knastbøsningerne · 12 to trykoliekamre 27» som gennem anslagene 30 22 på ringen 21 er adskilte fra hinanden. Trykket i den i dem værende styreolie trykker på den ene side anslagene 26 mod vingerne 22 og bevirker - ved trykaflastning på den ene side og ved trykforøgelse på den anden side - på bekendt måde en drejning 149902 7 1 af knastbøsningerne 12 i forhold til ringen 21 og dermed en omstyring af brændstofpumpeknasterne 13, som er fastmonteret på knastbøsningerne.From both sides, in the mounted state, the cam bushes 12 pivotally mounted in accordance with the invention on the camshaft 4 are pushed into the ring 21 with its 25 also diametrically opposite, inwardly projecting abutments 26. They are connected to each other through these abutments 26 by means of screws. In this way, two pressure oil chambers 27 »are formed between the bushings · 12 which are separated from each other through the stops 30 22 on the ring 21. The pressure in the steering oil contained therein presses, on one side, the abutments 26 against the wings 22 and causes - by pressure relief on one side and by pressure increase on the other - in a known manner a rotation 149902 7 1 of the cam bushes 12 relative to the ring 21 and thus a re-routing of the fuel pump lugs 13, which are fixedly mounted on the cam bushes.
5 Radialt udad afdækkes de sammenskruede knastbøsninger 12 og oliekamre 27 af en muffe 28, over hvilken en - også i fig. 1 vist - olietilførselsring 29 skydes ind. Olietilførslen i ringen 29 sker for den ene retning gennem en kanal 30 i en indre ringnot 10 31 og fra denne gennem kanal 32 i muffen 28 til et af oliekamrene 27. for den anden drejeretning flyder olien gennem en kanal 33, en not 34 og en kanal 35.5 Radially outwardly, the screwed-in bushings 12 and oil chambers 27 are covered by a sleeve 28, over which one - also in FIG. 1 shown - the oil supply ring 29 is inserted. The oil supply in the ring 29 is for one direction through a channel 30 in an inner ring groove 10 31 and from this through channel 32 in the sleeve 28 to one of the oil chambers 27. For the other direction of rotation, the oil flows through a channel 33, a groove 34 and a channel 35.
15 Ud af oliekamrene 27 ind i spalterummet mellem styreakslen 4 og bøsningerne 12 sivende lækageolie fremkalder en smøring mellem disse to relativt i forhold til hinanden bevægede dele.15 Out of the oil chambers 27 into the gap between the guide shaft 4 and the bushings 12 leaking leakage oil causes a lubrication between these two relatively moving parts.
20 På bøsningerne 12 er styreknasterne 13 anbragt udvendig til styring af brændstofpumperne (fig. 1), således at de er fast forbundet med deres respektive til hver knast hørende bøsning 12. Yderligere følger i retning mod enden på kamakslen 4 til dennes dreje- 25 lige lejring lejerne 11, medens der helt yderst findes de to fast mef akslen 4 forbundne styreknaster 8, ved hjælp af hvilke de to løftepumper 7 (fig.20 On the bushings 12, the control knobs 13 are arranged externally to control the fuel pumps (Fig. 1), so that they are firmly connected to their respective bushings 12. Each of the camshafts 4 further follows towards the end of the camshaft 4 to its rotatable 25. bearing the bearings 11, while there are at the very extreme the control knobs 8 connected to the shaft 4 by means of which the two lifting pumps 7 (fig.
1) til åbning og lukning af udstødningsventilerne styres.1) for opening and closing the exhaust valves is controlled.
