- a rotary piston machine is a power machine in which the parts that perform mechanical work only perform rotational movements. This design offers various ways to convert energy into rotary motion.

- another variant is drawn, in the two coaxial waves W1 and W2 the piston sets in the device via two separate
- Stepper motors EMGI and EMG2 be controlled.
- FIG. 9 shows an example in which the rotary piston machine is driven by gear sets from the outside, which use non-circular gears Z1 to Z4, which lead to a pendulum movement of the piston sets K1 and K2.
- the housing G is sealed by the covers D1 and D2 and closed laterally.
- a motor generator EMG is connected in each case, which can also serve as a generator.
- FIG. 32 shows a side view of two non-circular gears ZR1 and ZR2 which cause an oscillating drive of the axis A1 when the gear ZR2 and the axis A2 execute a uniform rotation.
- gears are found in the transmission in Figure 9 use.
- a reduction ratio 2 to 1 is provided from a uniformly rotating axis A2 to the pendulum drive via A2 with respect to the average rotational speed.
- FIG. 11 shows other embodiments of toothed wheels ZR1 to ZR4 for pendulum drives which, as described above, produce four oscillations as externally toothed wheels or, as shown in the lower part of the figure, also with internally toothed wheels ZR3. This latter variant is used in the lower part of Figure 9.
- FIG. 34 shows an oscillating drive of the pistons K1 and K2, in which a rotation of the pistons K1 and K2 against one another is effected via a spindle SP with steep left and right turns to the shafts W1 and W2 by a periodic lateral oscillation of the spindle S. can.
- the displacement of the shaft S is effected via cam controls He1 to He4, which are designed so that roller tracks or cams have a corresponding number of corrugations, as required for the pendulum rotation of the pistons K1 and K2.
- a mechanically coupled via a spline sliding axis S transmits a uniform rotation to a motor generator.
- Figure 35 shows a view of a rotary piston machine in which the pendulum gear is integrated into the central shaft sections, so that a compact device is formed with a uniformly rotating outer shaft.
- Figure 37 15 shows an outer gear for a rotary piston device, in which the
- Pendulum is caused by eccentrically mounted, circular gears, whereby a simpler manufacturing is possible.
- Figure 38 shows an embodiment of a pendulum drive, in which a gear pair is used in the manner of a motion picture projector.
