Definitions

  • the invention relates to an internal combustion engine which works on the principle of rotation and can be used to drive motor vehicles, aircraft and equipment.
  • the present invention relates to a rotary piston engine or machine, consisting of a cylindrical housing with side covers and two centrally mounted, double-acting rotary pistons, which perform a reciprocating movement at a certain angle.
  • a similarly constructed motor has become known from DE 42 01 993 Cl. The first results of this machine compared to the Wankel engine are astonishing. The simple construction of the construction results in a very favorable price-performance ratio of this engine.
  • the object of the invention is a rotary piston engine, primarily for driving motor vehicles, aircraft and equipment. This should be easy to manufacture, guarantee absolute tightness and enable a reduction in the toxic content in the exhaust gases. Compared to the Wankel engine, it should have smaller dimensions and a lower mass and should be characterized by good performance. At the same time, it should require less fuel, but still be easy to maintain, robust and suitable for continuous use. According to the invention, this is achieved in a rotary piston engine of the above type in that two interlocking, double-acting, axially symmetrical rotary pistons move back and forth by an angular amount in a cylindrical housing.
  • two disks guide the control of the inlet and outlet bores and the spark plugs, in the cylinder housing a rotational movement with the mean angular velocity of the rotary lobes in one direction.
  • the power transmission takes place by means of a lever, connecting rod and crank in a rotary motion.
  • the engine according to the invention is distinguished by a very simple construction. This makes it possible to reduce the manufacturing costs considerably. All essential components of the engine have easily grindable cylindrical surfaces and can be easily manufactured with high precision. Sealing the motor is also no problem. Almost absolute tightness can be achieved with conventional sealing elements. Due to the special wedge-shaped design of the combustion chambers and the uniformly high temperatures of the rotary lobes and the cylinder wall, it is possible to achieve complete combustion and thus to considerably reduce the proportion of toxic exhaust gases, especially carbon monoxide. Another advantage of the motor is its small dimensions. In comparison to a Wankel engine of the same power, the dimensions of the engine according to the invention can be reduced by approximately 20%.
  • the motor according to the invention does not require a separate distribution system for the fuel-air mixture, since the bores provided for this purpose are closed and opened automatically by the rotor parts.
  • the engine can be equipped with known ignition and carburetor systems.
  • the motor can also be lubricated in a conventional manner.
  • FIG. 1 shows a longitudinal section through the engine
  • FIG. 2 shows a section through the engine in the operating state, according to the line A-A in FIG. 1
  • FIG. 3 shows a section through the engine in the operating state.
  • the line A-A in FIG. 1 the top view of the control disk for ignition and inlet openings
  • FIG. 5 shows a cross section along the line B-B in FIG. 4
  • FIG. 6 is a top view of the housing cover with inlet openings and distributor

  • the disk 4 contains three bores 14 arranged symmetrically offset by 120 ° for the discharge of the exhaust gases.
  • the radii of the bore arrangement in the housing covers are identical to those of the disks in the housing, so that the bores of the disks which run against one another coincide.
  • Both disks 2 and 4 rotate synchronously with the average angular velocity of the rotary pistons 7 and 8 and slide on the housing covers 3 and 5.
  • two symmetrically opposite lamellae are each designed as rotary pistons and thus inserted into one another, that the fins of one rotor part 7 fit into the free space between the fins of the other rotor part 8.
  • the two rotary piston shafts 7a and 8a are rotatably connected to one another as a guide by means of bolts 6 and perform an opposite back and forth rotation.
  • the size of the slats 7 and 8 is such that their end faces slide on the control disks 2 and 4. Due to the special design of the lamellae, four wedge-shaped chambers 21, 22, 23, 24 are thus formed in the motor housing, the volume of which can be changed by the movement sequence of the rotary pistons 7 and 8.

Abstract

Un moteur à combustion interne qui fonctionne selon le principe de rotation doit être économique en carburant, avoir des dimensions et des volumes réduits par rapport aux moteurs à piston rotatif Wankel, être robuste, puissant mais économique à produire. Ce moteur comprend un carter cylindrique dans lequel deux pistons rotatifs qui sont en prise, qui agissent ensemble et qui sont montés symétriquement par rapport à un axe tournent en avant et en arrière sur un angle déterminé. En même temps, deux disques de commande des passages d'admission et d'échappement, ainsi que des bougies d'allumage, effectuent un mouvement de rotation dans une seule direction à l'intérieur du carter cylindrique à la même vitesse angulaire moyenne que les pistons rotatifs. Les forces sont transformées en un mouvement de rotation par un levier, une bielle motrice et une manivelle.
