Definitions

  • the invention relates to a central-axis rotary piston internal combustion engine with a rotor rotating within a circular stationary shell at a uniform speed and connected to the output shaft, which consists of end face parts and a non-rotatably connected drum, the openings for the inlet and outlet evenly 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.
  • the slots arranged on both sides of a piston connected to the drum jacket in the drum jacket be provided in two radial planes, so that in the housing jacket in each of the two radial planes there is an inlet and an outlet slot opposite the corresponding slots of the others Radial plane are offset by an angle of about 90 0 , is required.
  • the invention has for its object to keep the length of the sealing limit small with as few relatively rotating components as possible 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 above construction and by simplifying the arrangement of the drum openings Achieve control and 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 locally occurring 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 jacket-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 piston 4, against which an outer end disk 46, 46' bears.
  • These disks have bores and recesses on their mutually abutting surfaces to form lubricating oil. and cooling oil passages 47.
  • the pistons 5 of smaller mass which are integrally formed with their hub 51, circulate 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.
  • One bearing 91 of each connecting rod 9 is pushed onto this crank pin, the other, also closed bearing 92 of which 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 1 , which together with the cover shell 3 forms the housing for a gear pump 33 designed as a sickle pump.
  • the bearing flange 48 On the one hand, and the output shaft 11, which is rigidly connected thereto, on the other hand, the parts rotating at a uniform speed are mounted in bearing shells 24 and 34 of the cover shells 2 and 3.
  • 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 inner disks 45, 45 1 are on the end faces of the hub of the pistons 5 engaging in annular grooves of the outer end face disk 46 or with ring strips of this disk cooperating ring strips 52 are provided, the flanks of which form an acute angle with the axis of rotation of the pistons 4, 5, pointing radially outward and in the direction of the cover shell 2.
  • the cooling oil flows through the axial tube 47 surrounding annular cylindrical channel to those provided in the small piston cooling coils and to the between the front-side inner and äuße - ren discs 45,46 channels formed as well as the meander-like arranged in the drum 42 cooling channels.
  • 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 transmission space into tangentially opening drain openings (not shown) in the housing jacket 1.
