Definitions

  • the invention relates to a central-axis rotary piston internal combustion engine with a rotor rotating within a circular stationary jacket at a uniform speed and connected to the output shaft, which consists of end face parts and a drum which is connected to them in a rotationally fixed manner and has openings for the inlet and outlet which are uniformly distributed over their circumference and on their inner circumference, evenly distributed over them, have radially inwardly extending pistons which, together with counter-pistons connected to one another via a hub and rotating at non-uniform speeds, delimit working chambers.
  • DE-A-2 606 360 also shows a complex construction with only one spark plug arranged on the housing circumference and sealing strips arranged axially in the housing jacket and resulting in non-closed sealing limits.
  • the invention is based on the object, in the formation of a central-axis rotary piston internal combustion engine of the type mentioned as a high-performance machine in simplification of the aforementioned construction, to keep the length of the sealing limit small with as few components rotating relative to one another and by simplifying the control by arranging the drum openings to achieve and to create favorable combustion chamber conditions and favorable conditions for high compression and optimal combustion of the fuel.
  • the construction according to the invention considerably simplifies the construction of the aforementioned internal combustion engine, shortens the overall length of the sealing limits and exposes the seals to less wear, which is further reduced by the fact that the surfaces they sweep do not have any local temperature peaks, but rather as a result of the four-stroke operation have a more uniform temperature due to the gas exchange cooling.
  • the engine housing consists of the cylindrical shell-shaped part 1 and the two side cover shells 2 and 3.
  • threaded holes for receiving two spark plugs 18 and recesses 19 are provided for the inlet of the mixture and the outlet of the burned gases.
  • the drum 42 with which the pistons 4 are integrally connected, rotates within the housing shell 1.
  • the working spaces are delimited by an inner disk 45, 45 'rigidly connected to the pistons 4, against which an outer end disk 46, 46' bears.
  • These disks have bores and cutouts on their mutually abutting surfaces to form lubricating oil and cooling oil channels 47.
  • the pistons 5 of smaller mass which are integrally formed with their hub 51, rotate at a non-uniform speed.
  • the output shaft 11, on which the hub 51 of the pistons 5 is mounted is formed in one piece with the outer disk 46.
  • the planet gears 7, which are rotatably connected to one in the end disks 46, 46 'of the piston 4 shaft 8 the other end one Forehead crank with a short crank pin 81.
  • On this crank pin one bearing 91 is pushed a connecting rod 9, the other, also closed bearing 92 is pushed onto a bolt 10 which is eccentrically inserted in the hub 51 of the piston 5.
  • the elastic mounting of the internal gear 6 is brought about by the fact that in the outer edge region of the internal gear 6 end faces are inserted into this elastic sleeves 61, into which bolts 22 inserted into the bores of the cover shell 2 engage.
  • the cover shell 2 is connected to the housing shell 1 by means of screw bolts 21, the cover shell 3 by means of screw bolts 31.
  • a bearing flange 48 is connected to the outer front disk 46 ', which together with the cover shell 3 forms the housing for a gear pump 33 designed as a sickle pump.
  • the inlet and outlet control openings 43 are designed as recesses which narrow radially inwards and are arranged symmetrically to the axial center plane of the pistons 4 and which merge into troughs 4 of the combustion chambers which are delimited by recesses of the pistons which are open at the edge.
  • sealing rings 49 are provided which comprise openings 43 and which seal off the working spaces.
  • the lubricating oil is fed to the bearings 24 and 34 and the bearings of the crankshafts 8 directly, the bearings of the connecting rods 9 indirectly via channels arranged in the hub 51 and the bolts 10 through the axial tube 47.
  • the cooling oil passes through the annular cylindrical channel surrounding the axial tube 47 to the cooling coils provided in the small pistons and to the channels formed between the end-side inner and outer disks 45, 46 and to the cooling channels arranged in a meandering manner in the drum 42.
  • labyrinth arrangements are provided in a manner known per se for calming and reducing the gas flow.
  • the inner disks 45, 45 ' have a larger outer diameter than the drum 42, so that spray oil is rejected from the gear chamber and cannot reach the inlet and outlet openings 19.
  • the outer disks 46, 46 ' have ribs on the circumference, which convey the oil from the gear chamber into tangentially opening drain openings (not shown) in the housing jacket 1.
