Definitions

  • the invention relates to an internal combustion engine with a rotor having a circular cross section and an annular stator surrounding the rotor.
  • a rotary piston engine is known, with a rotor with a circular cross section and a circular stator surrounding the rotor, a flap being pivotally mounted on the inside of the stator, which flap can be folded back into the stator by a working cam on the rotor .
  • the engine operating on the principle of expansion is liable
  • the rotor is sealed from the stator by a sealing strip that is strongly subject to wear.
  • the motor has a dead center, which is given by the fact that the outlet opening for the gas in the rotor and the outlet opening in the stator corespond to one another in a certain position.
  • this engine also suffers from the fundamental disadvantage of all known rotary piston engines of having practically no torque in the lower speed range.
  • the invention is therefore based on the object of providing an engine which avoids the disadvantages of known engines, which operates in particular as a rotary engine and which is at the same time able to process alternative fuels, in particular gaseous hydrogen, without problems and as environmentally friendly as possible.
  • the invention is based on an internal combustion engine with a rotor with a circular cross section and an annular stator (inner rotor) surrounding the rotor.
  • the invention consists in the fact that in the peripheral surface of the rotor there are recesses in the form of circular sections as expansion spaces, at one end of which a combustion chamber is arranged and the other end of which runs out into a ramp, and in that flaps are pivotally mounted on the inside of the stator and are mounted in the Recesses of the rotor for receiving the forces of the expanding combustion gases can be folded in and can be folded back into the stator by means of the ramp.
  • This engine is characterized by the following properties: It can be operated with simple hydrogen gas, which is oxidized with the oxygen in the air.
  • FIG. 1 shows the external view of a motor according to the invention consisting of four motor units I, II, III and IV, for example. It is possible to build the engine from more or from fewer units.
  • the power output by the engine is taken from a power take-off shaft Z which, in the example shown in FIG. 1, is arranged in the center of the engine with respect to the engine units and which is driven by the engine shaft in a manner known per se via a bevel gear.
  • On one side of the engine is a compressor BK, which supplies the fuel gases, preferably hydrogen, to the engine, while on the other side of the engine a second compressor LK is driven by the engine, which provides the engine with the oxidizer in the form of air, which is necessary for combustion or also as pure oxygen.
  • FIG. 2 shows the axial view of the engine 1 with the interior open, the direction of view forming a small angle with the engine axis 4.
  • the view shows the two main parts of the motor 1, namely the rotor 2 and the stator 3, from which it can be seen that the motor 1 is designed as an internal rotor in this exemplary embodiment.
  • the rotor 2 has in its circumferential surface 21 circular cutouts 22 as expansion spaces for the combustion gases.
  • a combustion chamber 23 is arranged at one end of the expansion space 22, while the other end ends in a ramp 24.
  • flaps 32 are pivotally mounted on the inside 31 of the stator, which flaps can be folded into the recesses 22 of the rotor 2 to absorb the forces of the expanding combustion gases and can be folded back into the stator 3 by means of the ramp 24.
  • this is the convex version of the internal combustion engine 1 with respect to the combustion chambers 23.
  • the engine 1 shown in FIG. 2 it has four drive units, each consisting of four expansion spaces 22 with eight flaps 32 and four combustion chambers 23.
  • this is only an example and that it is readily possible to provide 2, 3, 5, 7, 8 or even more drive units.
  • the number of flaps is also arbitrary.
  • the combustion chambers 23 are fastened with arms 43, in the exemplary embodiment with four arms 431, 432, 433 and 434 each, to the arm supports 42, in the example the two arm supports 421, 422.

  • the outer ring 51 is shown on one side.
  • An identical ring 52 is located axially on the opposite motor side.
  • the rotor 2 is fixed and supported in the stator 3 by two outer ring carriers 61, 62.
  • an outer ring carrier 61 is shown, while the second outer ring carrier 62 is axially seen on the other engine side.
  • the rotor axis 4 is mounted in a manner known per se with a ball bearing 63 in the outer ring carriers 61, 62.
  • the stator 3 consists of annular lamellae 35, of which the lamellae 351, 352, 353 are designated in FIG. 2. Spacers 36 are located between the fins 35.
  • the stator block consisting of fins 35 and spacers 36 is held together by connecting bolts 37 passing through the stator. 1 and 2 show one of the connecting bolts 37.
  • stator 3 In a second embodiment of the stator 3, the stator 3 consists of segments in the form of circular sections, held together by fixings. These segments can preferably consist of suitable light metals or alloys customary in engine construction.
  • the stator 3 On its inside 31, the stator 3 has recesses 33 for receiving the flaps 32. These recesses 33 are preferably complementary to the shape of the flaps 32 or form-fitting with them. It is very advantageous for the flaps 32 to expand space 22 To give shape to a spoiler. The spoiler shape causes the flue gases flowing to the flaps 32 to pull the flap 32 into the expansion space 22, as shown by the arrow P 3 in FIG. 6b.
  • the motor or rotor axis 4 is shown in FIGS. 5a to 5e.
  • the rotor axis 4 consists of individual axially pierced axis elements 41, an axis consisting of four elements being shown in FIG. 5a, for example.
  • Figure 5b is a side view of an axle member 41
  • Figure 5c is a perspective view.
  • each axle element 41 has an axial bore 43.
  • the latter has semicircular recesses 441 in cross section, which together with the corresponding recesses of the next axle element 41 form a radial bore 44, such as this can be seen from Figure 5a.
  • the rotor axis 4 composed of the individual axis elements 41 is also provided with an axial bore.
  • the axially pierced axis 4 is required in order to supply the two reaction gases, preferably hydrogen and air, to the combustion chambers 23 through the axial bore 43 and the radial bores 44.
  • FIG. 5d shows the rotor axle 4 in the flanged-together state, in that the individual axle elements 41 are flanged together by two half-shells 451, 452 and half-ring-shaped arm supports 461, 462, which are pulled together by screws, and thus form a rigid motor or rotor axle 4.
  • the combustion chamber 23 consists of the outlet nozzle 232, the combustion chamber 231, two inlet nozzles 233, 234 for the two reaction gases or fuel gases and an ignition probe 235. Hydrogen and air are preferably used as the combustion gases.
  • Two fuel gases, which are brought together under certain pressure conditions in the combustion chamber 23, are ignited by the ignition probe 235, which projects into the combustion chamber 23.
  • the amount of the individual gases and their pressure can be precisely regulated and set by the compressors BK, LK described below.
  • the ignition probe 235 it is also possible to ignite the ignition corresponding to the respective gases. H. Ignition temperature and ignition torque, precisely set.
  • the two toggle levers 323 lie one behind the other on both sides of the flap 32, so that only one is visible in the figures is.
  • the valve linkage it is also possible for the valve linkage to consist of two straight and one toggle levers, in which case a straight lever is located on each side of the valve 32.
  • the pivoting movement of the flap 32 into the expansion space 22 is limited by a stop lug 324 molded onto the toggle lever 323 and abutting the flap 32 in the lowered position.
  • This stop lug 324 limits the lowering movement of the flap 32 in such a way that the underside of the flap 32 is only a very small distance from the inner boundary 25 of the expansion space 22. This distance is only about 5/1000 mm.
  • the flap 32 can be pivotably supported by a flap linkage and a pivotable part of the outer boundary 34. It would also be possible to arrange the flap 32 in a rail without linkage, similar to an elevator, in or out of the expansion space 22.
  • the flaps 32 of the engine 1 are located in the expansion space 22 and absorb the forces of the expanding combustion gases.
  • the rotor 2 rotates relative to the stator 3, with the result that, as shown in FIG. 6c, the front edge 321 of the flap 32 abuts the ramp 24 and initiates a folding back movement.
  • the flap 32 is shown in two successive times. The flap 32 is folded back into the stator 3 by two sliding pins 325a, 325b located in the front edge 321 of the flap 32 and sliding on the ramp 24 (FIG. 7).
  • the flap 32 is shown in an enlarged view.
  • the flap 32 is preferably cast from a light metal customary in engine construction.
  • two sliding pins 325a, 325b are located in the front edge 321.
  • the slide pins 325a, b do not touch the inner boundary 25.
  • the sliding pins 325a, 325b come into contact with the inner boundary, as can be seen from FIG. 8b, and slide along the edge of the inner ring 261. Due to this very short-term contact of the pins 325a, b with the inner ring 261, 262, the sliding pins are only subjected to very little stress and therefore have a very long service life.
  • the pins 325a, b can be readjusted or readjusted very easily in the event of excessive abrasion.
  • wheels which roll on the ramp 24 are in the front edge 321 device. Rolling wheels can also be attached on the opposite edge 327, which, when the combustion chamber 23 is rotated past, convert the sliding friction of the flap 32 into rolling friction and thus protect the flap material.
  • a roller bearing is arranged in the ramp 24, on which the front edge 321 of the flap 32 can roll directly.
  • Figures 9a, 9b show the essential sealing elements of the motor 1.
  • the sealing elements must on the one hand seal the expansion space 22 against the stator 3 and the flaps 32 against the rotor 2.
  • Figure 9a shows a section through the combustion chamber 23 and the expansion space 22 along the line IXa - IXa of Figure 9b.
  • the seal 611 Below the inner boundary 25 is the seal 611 and on both sides next to the front edge of the combustion chamber 23, a sealing strip 612a, 612b and seal the expansion space 22 against the outer rings 51, 52.
  • the flap 32 is also sealed by sealing strips 326a, 326b during its pivoting movement with respect to the outer rings 51, 52.
  • the seals 611, 612a, b and 326a, b by a higher accuracy of fit of the inner boundary 25, combustion chamber 23, combustion chamber cover 236 and flap 32.
  • Another possibility is to manufacture the inner limiting part 25 and / or the flap 32 from self-sealing material.
  • the previously described engine version can be referred to as the convex version of the engine 1 with respect to the combustion chambers 23.
  • Such an engine can be referred to as the concave version of engine 1 with respect to combustion chambers 23.
  • a motor is conceivable in which the rotor 2 is stationary and the stator 3 is rotating. One can speak here of a reversal of the rotor-stator property.
  • compressor BK on one engine side, which supplies the fuel gases, preferably hydrogen, to the combustion chambers 23 and on the other engine side a compressor LK, which in the combustion chambers 23 contains the oxidizer necessary for combustion, for example in In the form of air or pure oxygen.
  • FIG. 10 shows a longitudinal section through the fuel compressor BK, which is now given the reference number 7.
  • the compressor 7 mainly consists of the two housing parts 71 and 72 and the turbine axis 73.
  • the housing part 71 is firmly screwed to the rotor axis 4, whereas the housing part 72 is mounted on the stator 3.
  • the housing part 71 therefore rotates at the engine speed.
  • the fuel gas is located in the fuel chamber 74 and is supplied to this space via the line 75.
  • FIG. 1 shows how the compressor axis 73 is driven by the motor 1 or rotor 2 via a gearbox Gt1.
  • the transmission Gt1 is preferably a reduction gear, so that the speed of the compressor blades 76 is between "zero", the speed of the stator 3, and the speed of the rotor 2.
  • annular labyrinth seals 771, 772, 773 are of particular importance to the invention.
  • the labyrinth seals each consist of the stationary annular disks 771, 773, between which the Motor shaft 4 rotating annular disc 772 is located.
  • This increase in density with greater viscosity increases the sealing effect of the labyrinth seal, which is particularly important when hydrogen is used as a fuel gas.
  • FIG. 11 is a cross section through the oxidizer compressor LK, which is now given the reference number 8.
  • the compressor 8 is constructed in such a way that it supplies air to the combustion chambers 23. For this reason, the double seal necessary in the fuel gas compressor 7 is not required.
  • the compressor 8 consists of the two housing parts 81, 82.
  • the housing part 81 is firmly screwed to the rotor axis 4, whereas the housing part 82 is mounted on the stator 3.
  • the air is drawn in by the turbine blades 86 through the air filter 84.
  • the compressor blades 86 are fixed on the turbine axis 83.
  • FIG. 1 again shows how compressor axis 83 is driven by Mtor 1 or rotor 2 via a transmission Gt2.
