Definitions

  • the invention relates to a rotary piston machine with at least two side by side rotatable independently of one another about the same longitudinal axis. mounted in preferably only one direction rotatable support disks, which are provided on their radially outer sides at regular intervals with pistons, the pistons on each of the two disks have the same cross-sections and alternately a piston of the one disc and a piston of the other disc in the protrude the same rotationally symmetrical cavity of a housing arranged coaxially to the longitudinal axis.
  • crank drive is required in each of these machines to convert the reciprocating motion into a rotary motion.
  • the crank mechanism makes machines with piston movement relatively complex and heavy.
  • a rotary piston internal combustion engine which works on the principle of the four-stroke gasoline engine and has controlled intake and exhaust valves.
  • the in an annulus of Circular cross-section piston pairs move alternately in cycles by a certain angle of rotation, so that the four cycles of suction-compress-expand-eject are carried out on the front or rear of each piston in succession by increasing and decreasing the distance to the preceding or following piston.
  • Clock feed, piston width, position of the valves and the spark plugs arranged centrally between them are so matched that three rotationally symmetrically arranged valve groups and spark plugs are required for each pair of pistons.
  • a valve group consists of an inlet and an outlet valve, which are installed opposite each other in the wall of the annular space parallel to the axis of rotation of the engine. From Fig. 2 of DE-PS 582 181 it can be seen that the annular space has only a very small proportion compared to the total volume of the internal combustion engine.
  • Rotary piston machines which only have rotating parts are also known. Closed working rooms with rigid walls, at least one of which is moved in such a way that a variable volume of the working room results, are characteristic of rotary piston machines.
  • the variable volume is formed between a power section and a shut-off section.
  • the rotary piston engine contains a stationary shut-off part and a power part which moves with its center of gravity on a circle and additionally rotates around a center of gravity.
  • the piston of the rotary piston engine has the shape of a triangle with convex sides, in which there is an internal toothing on one side which meshes with a fixed gear. The sealing of the work rooms is difficult with the rotary piston engine.
  • the invention is based on the object of developing a rotary piston machine which has a construction which is as simple as possible - -
  • the object is achieved by the measures described in claim 1.
  • the rotary piston machine specified in claim 1 can in principle be used as a power or work machine with appropriate adaptation to the respective working medium. Only a few components are required.
  • the rotary piston machine according to claim 1 is therefore versatile and inexpensive to manufacture.
  • the disks are preferably only rotatable in one direction. Between two adjacent pistons, the piston movements create working spaces with variable volumes. If the disks can only rotate in one direction, depending on the type of rotary piston machine as a power or working machine, a torque is delivered or received in this direction of rotation. A stopping device or the like can be used to block the rotation of the disks in one direction.
  • An inevitable mutual braking or acceleration of the two disks of a rotary piston machine is achieved, for example, by gear transmissions, chain transmissions, belt transmissions, lever transmissions and / or cam disks, wherein the above-mentioned transmission types can also be combined with one another.
  • At least the radially outward-facing sides of the piston heads are expediently adapted to the shape of the inner side of the cavity adjoining them. Only very small clearances are therefore required between the pistons and the inside of the cavity, which can be sealed well by appropriately shaped seals that can be inserted in the grooves of the pistons.
  • the disks are at a small distance from each other on one side of the plane of symmetry with the pistons running through the center of the pistons perpendicular to the longitudinal axis connected. There is preferably a seal between the disks.
  • the sealing of the working chambers between the panes is therefore relatively simple and easy.
  • the housing is arranged at a short distance from the pane walls. It is therefore also possible to insert a seal in the grooves of the panes and / or the walls in order to seal the work spaces at these points.
  • a favorable adaptation to the flow of the working medium is achieved if the front and the rear surface of the piston are designed to be inclined with respect to the longitudinal axis of the rotary piston machine.
  • pairs of passage openings one of which is provided for the supply and one for the discharge of the working medium, at regular intervals with respect to the passage openings intended for the same function along the cavity.
  • the passage openings are designed in the manner of slots and can be closed and released in each case by the pistons and / or support disks.
  • the change in the working medium is controlled via the pistons and / or support disks themselves. It is also possible to arrange the passage openings in the cylindrical outer wall.
  • a preferred embodiment is designed such that the passage openings provided for the supply or for the discharge of the working medium are each arranged in the opposite side walls.
  • the passage openings serving for the supply or discharge of the working medium are each connected to a fresh gas or exhaust gas duct running through 360 ° in the housing.
  • the number of pairs of passage openings and the number of ignition points are expediently the same, this number corresponding to half the number of pistons in the case of an internal combustion engine operating analogously to the two-stroke method or a quarter of the number of pistons in the case of the internal combustion engine operating analogously to the four-stroke method.
  • a number of spark plugs corresponding to the number of pairs of passage openings is arranged at regular intervals along the cavity, a fuel-air mixture being able to be fed into the cavity through the passage openings and being supplied with ignition voltages as a function of the rotational positions of the disks Spark plugs are ignitable.
  • This device works as a gasoline engine. It is also possible to feed air under pressure through the passage openings for the supply of the working medium, and to compress the air so high that fuel injected at the ignition point ignites itself. Such a device works as a diesel engine.
  • the ignition pressure controls a locking device which releases the leading pistons in the direction of rotation at the moment of ignition and connects the trailing pistons to the housing against the direction of rotation.
  • the trailing piston is advantageously brought close to the leading piston and the passage opening serving the supply of the working medium is only released when a minimum piston distance is reached.
  • the pistons can have different shapes. For example, piston pairs can also be used.
  • a rotary piston internal combustion engine with a minimum of moving parts represents the advantageous embodiment with only two pistons, the pistons extending over an angular range of preferably 90 °.
  • a plurality of seals can be arranged on the wide pistons, so that such a rotary piston internal combustion engine has a particularly robust operating behavior and requires no extreme accuracy with regard to the manufacturing tolerances.
  • a rotary piston internal combustion engine with a small diameter
  • favorable cross sections are achieved at the mounting location of a piston if only one piston or one piston group is connected to the inner shaft and the second piston or the second piston group is connected to a rotating intermediate housing .
  • the outer circumference of the cylindrical intermediate housing can be designed as an inner ring of a rolling bearing.
