There are known U "\ aufkolben" etors in which swish the single pistons are relatively mutually exclusive bswegenöer piston pairs each form a combustion chamber will.

There are already ventilated rotary piston motors relatively mutually moving pairs of pistons known, of which only the pistons of one pair of pistons act as working pistons, so that the number of pistons doubles as large as the number of distilleries (IBZ.PS 467 924).

acting piston pairs of different Hasse and daait also use of different sizes of initial area find, the process represents the control of one another Outlets of adjacent combustion chamber difficulties, in particular when one half of the pistons revolves at the same speed.

These difficulties are met by the invention Overcome the fact that the old uniform speed revolving, exhibiting greater moisture, to the outside widening pistons on their cylindrical Uefangefläche two in mutually parallel radial planes extending in opposite directions Open-edged recesses that enlarge the compression space on both sides and aa Uafang of the KoI-bengehäuses axially offset inlets and outlets are provided.

In the simplest EaIl the A 'and the outlets have the same angular width as the uvfangsfläche of the smaller piston, wherein the front in the rotational direction edge of the Auelasses includes from the rear edge of the inlet a distance corresponding to the distance between the camming surfaces of the two pistons in dead center.

Will nan the outlet and the inlet / control that the combustion gases schoiQ flow out before the pistons move in which are a dead center position, bsw. the fuel mix is still being sucked in after the pistons have already exceeded the other dead center position, so this can be done can be achieved in a simple manner that the angular width the inlet opening in the direction of rotation bsw. the angular width of the outlet opening opposite to the direction of rotation is enlarged.

sen arrangement can be achieved in a simple manner, that the inlet opening the outlet opening in each case the -above direction opposite direction terbreitert will.

If one wants to counteract such a widening of the opening where parts of the adjacent combustion chamber are located on the same side as the area of the opening, a further development of the invention struck through the widened opening 1 "swel by a web, thereby dividing openings that are separate from one another. What is prevented is the flow of 7 combustion products in the direction of rotation in the rear combustion chamber and higher brock into the direction of rotation in which there is less brucic at the end of the resting period. This would also counteract an effective flushing of neighboring combustion chambers, which is caused by the fact that the inlet opening on the side of the outlet opening is widened so much that it extends over the extension of the front edge of the outlet opening, for example. the outlet opening is widened accordingly.
