FOreliggande uppfinning avser en maskin med frilopande kolvar, som bilda tvenne rorliga delar med motsatt och synkroniserad rörelse, varvid en koly pa vardera delen loper i var sin av tvenne pa om maskinens mitt motsatta sidor belagna kammare, i vilken tryckluft fra.n en startanordning kan inforas for startning av maskinen genom oppnandet av en i startanordningen inbyggd startventil, som vid oppnandet plotsligt inslapper startluften i kamrarna, yarigenorn de i startlaget icke forreglingsbara kolvarna drivas mot sift inre vandlage. The present invention relates to a machine with free-running pistons, which form two movable parts with opposite and synchronized movement, wherein a coil on each part runs in each of two chambers located about the opposite sides of the machine, in which compressed air from a starting device can is introduced for starting the machine by obtaining a starting valve built into the starting device, which upon reaching suddenly lets the starting air into the chambers, in which case the pistons which cannot be locked in the starting layer are driven towards the inner water layer.
Uppfinningen ayser sarskilt men ej uteslutande bland ifragavarande maskiner drivgasgeneratorer, d. v. s. maskiner for alstring av gas under tryck. The invention uses, but not exclusively among the machines in question, propellant gas generators, i.e. machines for generating gas under pressure.
Det är redan bekant att medelst en enda ventilanordning infora luft for startning i tvenne startkamrar, som befinna sig ph bada sidor om maskinens mitt. Fran denna anordning fix avgrenad en ledning, som forbinder de bagge kamrarna och som leder till kamrarna vid de bagga andarna. It is already known that by means of a single valve device air is introduced for starting in two starting chambers, which are located on both sides of the center of the machine. From this device fixed a branch, which connects the ram chambers and which leads to the chambers at the ram spirits.
Uppfinningen kannetecknas darav, att hada kamrarna sta i permanent forbindelse med varandra medelst en oppen ledning, till vilken den med startventilen forsedda startanordningen är ansluten och vars area är sa stor, att tryckskillnader i startrummen omedelbart utj amnas. The invention can be characterized in that the chambers are in permanent connection with each other by means of an open line, to which the starting device provided with the starting valve is connected and whose area is so large that pressure differences in the starting rooms are immediately equalized.
Lampligen anyandas p kant salt de pneumatiska energiackumulatorerna, vilka under maskinens normala gang astadkomma Aterforingen av de rorliga delarna mot deras inre vandlagen, aven sasom startkamrar. The pneumatic energy accumulators on the edge of the lamp, which during the normal operation of the machine bring about the return of the moving parts to their inner water layers, also as starting chambers.
I sistnamnda fall och enligt en lamplig utfOringsform av uppfinningen anslutes till denna ledning, som permanent forbinder energiackumulatorerna for aterforingen, forutom startanordningen en regleringsanordning, som reglerar medeltrycket i ackumulatorerna i forhallande till maskinens drifttryck. Start anordningen och regleringsanordningen kunna forenas i ett gemensamt 1181j e. In the latter case and according to a suitable embodiment of the invention, in addition to the starting device, a control device is connected to this line, which regulates the average pressure in the accumulators in relation to the operating pressure of the machine. The start device and the control device can be united in a common 1181j e.
Bifogade ritning visor schematiskt som ett utforingsexempel a fig. 1 i axiell sektion en drivgasgenerator med frilopande kolvar, forsedd med en startanordning enligt uppfinningen, och a fig. 2 en variant av denna drivgasgenerator. Ifra.gavarande drivgasgenerator besta.r av en motorcylinder 1, i vilken tva kolvar 2° och 2°° lopa, som samverka i niirheten ay sina yttre vandlagen med tilloppsOppningar 3 och utloppsoppningar 4. The attached drawing shows diagrammatically as an exemplary embodiment of Fig. 1 in axial section a propellant gas generator with free-running pistons, provided with a starting device according to the invention, and Fig. 2 a variant of this propellant gas generator. The propellant gas generator in question consists of an engine cylinder 1, in which two pistons 2 ° and 2 °° run, which cooperate in the vicinity of their outer water layers with inlet openings 3 and outlet openings 4.
Vid vardera av motorkolyarna är en kompressorkolv 5°, 5" fastad, och dessa kompressorkolvar lopa i cylindrar 6°, r for matning av tryckluft medelst insugningsventiler 7 och tryckventiler 8 till en tryckkammare, som utgores ay den kapa 9, som omgiver moloreylindern 1. At each of the engine coils a compressor piston 5 °, 5 "is attached, and these compressor pistons run in cylinders 6 °, r for supplying compressed air by means of intake valves 7 and pressure valves 8 to a pressure chamber formed in the cap 9 surrounding the molore cylinder 1.
De pa sà salt utbildade bagge rorliga organen aro sammankopplade medelst en icke vi-sad synkroniseringsanordning, exempelvis utford pa det kanda shttet med vevstakar och sva.ngande pendlar. The ram-movable members thus formed are interconnected by means of a non-pointed synchronizing device, for example a challenge on the familiar surface with connecting rods and swinging pendulums.
Under kolvarnas rorelser utat, d. v. s. vid den drivande rorelsen, magasineras energi i energiackumulatorerna A°, A°°, som besta av kamrar med variabel volym, begransade av kolvarnas 5,° 5°° yttre kolvytor och cylindrarnas 6°, 6°° vaggar. Den salunda utbildade maskinen är naturligtvis pa. kant shtt fOrsedd med en icke visad anordning for bransleinsprutning. During the outward movements of the pistons, ie during the driving movement, energy is stored in the energy accumulators A °, A °°, which consists of chambers with variable volume, bounded by the outer piston surfaces of the pistons 5 °, 5 ° ° and the rocks of the cylinders 6 °, 6 °° . The well-trained machine is of course on. edge shtt Equipped with a device not shown for fuel injection.
Energiaekumulatorerna A', A°° tjana samtidigt som startcylindrar. For detta andamal är excentriskt i forhallande till maskinens langdaxel anordnad en ledning 23, Tars andar genomtranga kompressorkolvarna 5°, 5, vilka samtidigt styras ay rorledningens andpartier, pa vilka de aro glidbart lagrade. The energy accumulators A ', A °° serve at the same time as starting cylinders. For this purpose, a conduit 23 is arranged eccentrically in relation to the longitudinal axis of the machine. Tar's spirals penetrate the compressor pistons 5 °, 5, which are simultaneously controlled by the duct portions of the pipeline, on which they are slidably mounted.
ROnledningen 23 är exempelyis fastad yid de vaggar, i vilka tryckventilerna Oro anordnade. Denna rorledning, som är oppen till hela sin 2— — langd, forbinder permanent ackumulatorerna A° och A" med varandra salunda, att de tryck, som i varje ogonblick rd.da i de bagge ackumulatorerna, standigt aro lika. The line 23 is, for example, fixed to the cradles in which the pressure valves Oro are arranged. This pipeline, which is open to its entire length, permanently connects the accumulators A ° and A "to each other in such a way that the pressures which are present at any moment in the ram accumulators are constantly the same.
Ledningen 23 ãr medelst en ledning 22 ansluten till startanordningen, vilken bestar av en ventil 10 for regleringen av forbindelsen mellan en behallare 11 for startluften och ledningen 22. Ventilen. 10 är utford i ett styeke med en kolv 12, som loper i en cylinder 13. Det cylinderrum 14, som befinner sig pa motsatta sidan av kolven 12 fran ventilen 10 raknat, kan genom installning av en kran 15 eller dylikt efter onskan forbindas antingen med en tryekluftbehallare 16 eller med fria luften. En fjader 17 stravar att hMla ventilen 10 i slutet lage. En ledning 18, exempelvis i kolvens 12 lure, slapper fram luft genom backventilen 19 frail kammaren 14 till behallaren 11 men ej omvant. The line 23 is connected by means of a line 22 to the starting device, which consists of a valve 10 for regulating the connection between a container 11 for the starting air and the line 22. The valve. 10 is challenged in a styeke with a piston 12, which runs in a cylinder 13. The cylinder space 14, which is located on the opposite side of the piston 12 from the valve 10 raked, can by connection of a tap 15 or the like as desired be connected either with a compressed air tank 16 or with the open air. A spring 17 strains to hold the valve 10 at the end of the bearing. A line 18, for example in the lure of the piston 12, releases air through the non-return valve 19 from the chamber 14 to the container 11 but not vice versa.
Om i forsta Ogonblicket tryckluftbehallaren 16 medelst kranen 15 forbindes med kammaren 14, sit forblir ventilen 10 sluten, och tryclduften strommar genom ventilen 19 till behallaren 11, som uppladdas. Man behover darefter endast medelst kranen 15 satta kammaren 14 i forbindelse med ytterluften, for att ventilen 10 och kolven 12 skola lyftas av det tryck, som rader i behallaren 11. Ventilen oppnas salunda och startluften strommar in i ackumulatorerna och satter i gang maskinen. If at first the compressed air tank 16 is connected to the chamber 14 by means of the tap 15, the valve 10 remains closed, and the compressed air flows through the valve 19 to the tank 11, which is charged. The chamber 14 then only needs to be connected to the outside air by means of the tap 15, so that the valve 10 and the piston 12 will be lifted by the pressure which lines in the container 11. The valve is thus opened and the starting air flows into the accumulators and starts the machine.
For att astadkomma detta verkningssatt ar manoverkranen 15 sh anordnad, att den i lage I laddar behallaren 11, sisom ovan beskrivits, i lage III satter kammaren 14 under atmosfartryck och slutligen i lage II avstanger kammaren efter fullbordad start Mr att lata ventilen 10 sluta sig. To achieve this effect, the control valve 15 sh is arranged to load the container 11, as described above, in position III, to put chamber 14 under atmospheric pressure in position III and finally in position II to shut off the chamber after complete start Mr to allow valve 10 to close.
Enligt en sarskilt lamplig utforingsform av uppfinningen avgrenas fran ledningen 23, som permanent forbinder ackumulatorerna A°, A" med varandra, ej blott tilloppsanordningen for starttryckluften utan liven en anordning, som astadkommer regleringen av de tryck, som rada i ackumulatorerna. Den senare anordningen varierar medeltrycket av den luft, som befinner sig i ackumulatorerna i beroende av maskinens drifttryck, namligen i beroende av det av rnaskinens kompressordel aistrade trycket. According to a particularly suitable embodiment of the invention, from the line 23, which permanently connects the accumulators A °, A "to each other, not only the inlet device for the starting compressed air but the life is a device which achieves the regulation of the pressures radiating in the accumulators. the average pressure of the air present in the accumulators depending on the operating pressure of the machine, namely depending on the pressure exerted by the compressor part of the machine.
Denna tilloppsanordning for startluften och anordningen for reglering av trycket i ackumulatorerna anordnas lampligen i ett gemensamt holje, bildande ett lock 24, som lufttatt tacker en oppning i kapans 9 langsghende vagg. This inlet device for the starting air and the device for regulating the pressure in the accumulators are suitably arranged in a common housing, forming a lid 24, which air-tight fills an opening in the longitudinal cradle of the hood 9.
Ovannanmda regleringsanordning bestar lampligen av en slid 25, som glider i en cylinder 26, som vid sina bagge andar ãr Op-pen och star i forbindelse med kapans 9 inre. Denna slid innehaller tvenne kamrar 25° och 25°°, forsedda med oppningar 26° resp. 26", vilka samverka med en fast oppning 27, an ordnad pa cylindern 26 och forbunden med ledningen 22, varvid oppningen 27 tackes av sliden 25 i det a fig. 1 visade nollaget. The above-mentioned control device suitably consists of a slide 25, which slides in a cylinder 26, which at its ram spirits is open and stands in connection with the interior of the housing 9. This slide contains two chambers 25 ° and 25 °°, provided with openings 26 ° resp. 26 ", which cooperate with a fixed opening 27, arranged on the cylinder 26 and connected to the line 22, the opening 27 being thanked by the slide 25 in the zero layer shown in Fig. 1.
I kammarens 25° vagg aro oppningar anordnade, vilka regleras av ventiler 28°, som endast slappa in luft fran kammaren 25° till kapan 9, under det att kammarens 25" vagg ãr forsedd med oppningar, vilka regleras av ventiler 28°°, som endast slappa in luft frau kapan 9 till kammaren 25°°. In the cradle of the chamber 25 ° there are openings, which are regulated by valves 28 °, which only let in air from the chamber 25 ° to the cover 9, while the cradle of the chamber 25 "is provided with openings, which are regulated by valves 28 °°, which only let air from the hood 9 into the chamber 25 °°.
Denim regleringsslid ar forbunden med en kolv 29, som toper i en cylinder 30, varvid en av kolvens ytor star under det tryck, som rader i kapan 9 medelst en ledning 31, under det att kolvens andra yta star under ackumulatorernas medeltryck medelst en ledning 32 med mycket liten area direkt ansluten till en ledning, som star i forbindelse med ledningen 22. Denim control slide is connected to a piston 29, which tops in a cylinder 30, one of the surfaces of the piston being under the pressure which rows in the housing 9 by means of a line 31, while the other surface of the piston is below the average pressure of the accumulators by means of a line 32 with very small area directly connected to a line, which is connected to the line 22.
En fjader 33 paverkar dessutom kolven 29 i samma riktning som trycket fran kapan 9. A spring 33 also acts on the piston 29 in the same direction as the pressure from the cover 9.
Anordningen verkar salunda, att en aiming av drifttrycket under i ovrigt likartade forhallanden salter oppningen 26" i forbindelse med oppningen 27 och att, omvant, en minskning av detta tryck salter oppningen 26° i fOrbindelse med samma oppning 27. Nar ackumulatorernas medeltryck stigit till ett tryck, motsvarande drifttrycket, sit installer sig sliden i sitt nollage. The device thus acts as an adjustment of the operating pressure under otherwise similar conditions salting the opening 26 "in connection with the opening 27 and, conversely, a reduction of this pressure salts the opening 26 ° in connection with the same opening 27. When the average pressure of the accumulators has risen to a pressure, corresponding to the operating pressure, sit installs the slide in its zero position.
Da drifttrycket stiger, strommar salunda luft fran kapan 9 till ackumulatorerna och vice versa, naturligtvis under forutsattning, att tryckkurvan for ackumulatorerna liar en sadan form, att drifttrycket ligger mellan de extrema vardena pa trycket i ackumulatorerna. As the operating pressure rises, air thus flows from the hood 9 to the accumulators and vice versa, of course, provided that the pressure curve of the accumulators takes such a form that the operating pressure is between the extreme values of the pressure in the accumulators.
Da ej drifttrycket utan medeltrycket i ackumulatorerna varierar, an verkningssattet analogt, varvid slidens rorelse är omkastad. Since not the operating pressure but the average pressure in the accumulators varies, the mode of action is analogous, whereby the movement of the slide is reversed.
Slutligen kan awn en ventil 34 anordnas, som, nar man fore igangsattningen av maskinen onskar fora kolvarna i lampligt startlage, astadkommer en forbindelse av ackumulatorerna med ytterluften. Denna ventil anordnas lampligen i ledningens 22 vagg och manovreras sa, att den oppnar sig inht, dit en kran pa maskinens manoverstall, som Or ansluten till ett ror 36, slapper pit luft mot en kolv 35. Deana ventil 34 med sin kolv 35 anordnas lampligen i det lock 24, i vilket start- och regleringsanordningarna aro placerade, varigenom inga extra rorledningar bliva erforderliga. Finally, a valve 34 can be provided which, when it is desired to start the pistons in the suitable starting position, provides a connection of the accumulators with the outside air. This valve is suitably arranged in the cradle of the line 22 and is maneuvered so that it opens inwards, where a tap on the maneuvering machine of the machine, which is connected to a tube 36, releases pit air against a piston 35. This valve 34 with its piston 35 is suitably arranged in the cover 24, in which the starting and regulating devices are located, whereby no additional pipelines become required.
I den A. fig. 1 visade drivgasgeneratorn befinner sig tillforselanordningen for starttryekluften ungefar ph mitten av maskinen. I vissa fall kan det emellertid vara lampligt att placera denna anordning vid en av gavlarna till ackumulatorerna, sasom fig. 2 visa'', i vilken namnda starttrycklufttillforselanordning betecknats med B. In the propellant generator shown in Fig. 1, the supply device for the starting compressed air is located approximately in the middle of the machine. In some cases, however, it may be feasible to place this device at one of the ends of the accumulators, as Fig. 2 shows, in which said take-off compressed air supply device is denoted by B.
I detta senare fall blir skillnaden i avstand mellan startanordningen B och ackumulato- — —3 rerna A ochstor. For att trots denna skillnad uppna ungefar lika stora tryckforluster mellan startanordningen B °eh vardera av ackumulatorerna vid likformig starturladdning av dessa fir det lampligt att utfora tilledningen till den narmare startanordningen B belagna ackumulatorn med en trangre sektion an den till den vid andra an-den av maskinen belagna ackumulatorn. In the latter case, the difference in distance between the starting device B and the accumulators A becomes large. In order to achieve, despite this difference, approximately equal pressure losses between the starting device B ° eh each of the accumulators in the case of uniform starting discharge of these, it is convenient to perform the supply to the closer starting device B coated accumulator with a narrower section than that of the other machine coated accumulator.
F8r detta andamal utbildas enligt fig. 2 den del av 23;, av ifragavarande ledning, SOM slap-per in starttryckluft i ackumulatorn A, sàsom en ringformig spalt omkring ena andpartiet av den forbindelseledning 23b, som UfOr starttryckluft till ackumulatorn A°. Delarna 23, och 23b bilda tillsammans den alltid oppna forbindelseledning, som fix anordnad mellan de bagge ackumulatorerna A°, A°°. For this purpose, according to Fig. 2, the part of the conduit in question, which traps starting pressure air into the accumulator A, is formed as an annular gap around one end portion of the connecting line 23b, which provides starting pressure air to the accumulator A °. The parts 23, and 23b together form the always open connecting line, which is arranged fixedly between the ram accumulators A °, A °°.
Enligt fig. 2 insattes mellan tilloppsanordningen B for starttryckluften och farbindelseledningen 21, 23b en backventil 37, som slap-per fram starttryckluften endast i riktning fran startanordningen till ackumulatorerna. Harigenom farhindras, att icke onskad tryckluft under driften strommar fran forbindelseledningen till tilloppsanordningen far starttryckluft, vilket framfor alit kan undvikas, om startanordningen fir forsedd med organ, vilka efter starten astadkomma en stangning av ventilen 10 enligt fig. 1. According to Fig. 2, a non-return valve 37 is inserted between the inlet device B for the starting pressure air and the fairway line 21, 23b, which escapes the starting pressure air only in the direction from the starting device to the accumulators. This prevents unwanted compressed air from flowing from the connecting line to the supply device during start-up pressure, which can be avoided above all if the starting device is provided with means which after the start cause a closing of the valve 10 according to Fig. 1.
En liknande backventil kan naturligtvis anordnas aven i anordningen enligt fig. 1, dh den kan placeras efter ventilen 10 i starttryckluftens strOnniktning men fore ledningen 27 och ventilen 34. A similar non-return valve can of course also be arranged in the device according to Fig. 1, ie it can be placed after the valve 10 in the direction of the starting pressure air but the line 27 and the valve 34.
