Definitions

  • the invention relates to an internal combustion engine with a rotor having a circular cross section and an annular stator surrounding the rotor.
  • DE-C 283 368 describes an internal combustion engine with a rotor with a circular cross section and an annular stator (inner rotor) surrounding the rotor, a flap being mounted on the inside of the stator, which flap can be pushed back into the stator by a working cam on the rotor is, and in the circumferential 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; flaps can be pushed into the recesses of the rotor to absorb the forces of the expanding combustion gases and can be pushed back into the stator by means of a ramp.
  • the flaps however, have the disadvantage that their edges abutting the rotor are subject to high wear and tear, and thus all known sealing problems are present on the motor.
  • a rotary piston engine is known, with a rotor with a circular cross-section and an annular 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 is.
  • the flap is pressed into its closed position by a leaf spring and sealed against the rotor by a sealing strip.
  • the spring can no longer perform its task and the sealing strip is subject to rapid wear.
  • This motor which operates on the principle of expansion, has the further known disadvantage that the rotor is also sealed off from the stator by a further sealing strip which 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 correspond to one another in a specific position.
  • this engine also suffers from the fundamental disadvantage of all known rotary piston engines that there is 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 an inner part which is circular in cross section and an annular outer part surrounding the inner part, at least one circular section-shaped recess being present as an expansion space in the peripheral surface of the inner part, at one end of which a combustion chamber is arranged and the latter the other end is delimited by a working cam which ends in a ramp towards the expansion space and at least one flap is pivotally mounted on the inside of the outer part, which flap can be folded into the recess of the inner part to absorb the forces of the expanding combustion gases and through the ramp into the Outside part can be folded back.
  • the invention consists in that the flap towards the expansion space has the shape of a spoiler, against which the combustion gases flow in an effective flow-mechanical manner.
  • 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. An early ignition cannot take place, since hydrogen and air are brought together in a combustion chamber just before the ignition. A compress There is no phase of development. Subsequent detonation of unburned gas residues does not have an adverse effect on the engine or its operation, but is converted into additional drive energy.
  • the combustion chambers 23 are fastened to the arm supports with arms, in the exemplary embodiment with four arms 431, 432, 433 and 434, in the example to the two arm supports 421, 422.
  • the expansion space 22 extends between each two combustion chambers and is delimited towards the rotor axis 4 by an outer limiting part 34 and in the axial direction on each side by an outer ring 51, 52.
  • 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 fins 35, of which the fins 351, 352, 353 are designated in FIG. 1, for example. 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. In Fig. 1 one of the connecting bolts 37 is shown.
  • 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.
  • the flaps 32 have the shape of a spoiler towards the expansion space 22. The spoiler shape causes the flue gases flowing towards the flap 32 to pull the flap 32 into the expansion space 22, as shown by the arrow P3 in FIG. 4b.
  • the two toggle levers 323 lie one behind the other on both sides of the flap 32, so that in the figures only one is visible.
  • the flap linkage it is also possible for the flap linkage to consist of two straight and one toggle levers, in which case a straight lever lies on each side of the flap 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 performs a rotational movement with respect to the stator 3, with the result that, as shown in FIG. 4c, 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 by two sliding pins 325a, 325b located in the front edge 321 of the flap 32 and sliding on the ramp 24 (FIG. 5).
  • 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 325 a, b do not touch the inner boundary 25.
  • the sliding pins 325a, 325b come into contact with the inner boundary, as can be seen in FIG. 6b, 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 mounted in the front edge 321. 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.
  • 7a, 7b show the essential sealing elements of the motor 1.
  • the sealing elements have to seal the expansion space 22 against the stator 3 and the flaps 32 against the rotor 2.
  • 7a shows a section through the combustion chamber 23 and the expansion space 22 along the line VIIa-VIIa of FIG. 7b.
  • Below the inner boundary 25 is the seal 611 and on both sides next to the front edge of the combustion chamber 23 there is a sealing strip 612a, 612b and seal the expansion space 22 with respect to 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.
  • a motor is conceivable in which the rotor 2 is stationary and the stator 3 is rotating.
