In internal combustion engines of this type it is necessary to let the pistons run in a stationary housing and to attach the pistons rotating at equal angular velocity to the main shaft forming the output shaft and extending over the entire width of the piston housing and the transmission housing. This is necessary "nlt the non-uniform angular velocity unlaufenden piston at two mounted on the main shaft washers au _t fasten the old one of the rocker of the gearbox is connected. However, this results in difficulties both for the storage and for the seal and the design of the pistons.

These drawbacks are made possible by the invention by the fact that this well-known construction principle was abandoned and on a continuous hamptw @ lle, which was then enSglicht, over and over again unlaufenSen Eolben larger üae @@ rigid "it d @ a Stimiseitemteilea öee Kolbeneehttnses v®rbun-

On the gear housing is a gear in a known manner, preferably an internal ring gear with which the gear connected to the crankshaft, or a more = * number of such planetary gears meshes.

If you see a total of three in the transmission, each offset by 120 ° Crankshafts before, this results in the advantage of over the dome mounted on the crank pin to be able to center the swing arm without a central bearing, which as a result of this Due to the free adjustment option, all three gears are worn evenly. In this way it is possible to run the oscillating pistons exactly without any increased accuracy requirements of the gear parts to reach.

But it is with the most precise production of the transmission parts also possible to dispense with a separation of the rocker shaft and the sleeve carrying the oscillating pistons and to form these two parts in one piece, the transmission-side Stock of this sleeve is dispensable. Through this

will further simplify the construction and the Assembly as well as a weight saving of the unevenly moved Achieved masses, which allows higher speeds.

To reduce the moment of inertia of the oscillating to ^; Pistons, these are advantageously made of light metal and fastened to the piston carrier by means of cap screws in such a way that the screw heads rest against the inner circumferential surface of the piston carrier, if necessary against surfaces lying behind. The screws themselves are advantageously designed to be hollow, so that they serve as parts of the coolant line for supplying coolant to the pistons. Flat surfaces are provided on the piston carrier for proper and simple attachment of the pistons.

circumferential piston of greater mass is significantly simplified by the fact that it is connected to the end face parts of the piston housing by means of screws arranged on the end face are connected.

In addition, the construction according to the invention has the Advantage that an actuator part, preferably the gearbox-side, together with the uniformly rotating pistons

Since the oezillating acceleration of the pistons rotating at uneven speed causes relatively high peak loads in the gears, which have proven to be more critical than the bearing wear, it has been shown to be advantageous to reduce these peak loads at least to a certain extent by the to reduce the counterweight provided for the crankshaft. This is done in that the usually the crank pin diametrically opposite the counterweight by an angular amount, this * displacement is in the case of the internal toothing counter to the rotational direction of the crankshaft offset "The MAS depends inter alia on the Hasse the crankshaft and the coupling and the moment of inertia of the oscillating parts away.
