- the rotor 20 rotates but at a larger angle, as based on the position C1 of the slide guide 70 in Fig. 1a and in comparison to the position C2 in Fig. 1b can be seen.
- the rotor 20 thus precedes the cylinder liner 10, so that there is a positive rotational speed between the rotor 20 and cylinder liner 10.
- the rotation of the cylinder liner 10 by the angle B1, O1, B2 is smaller than the rotation of the rotor 20 by the angle C1, O1, C2.
- the rotor 20 thus rotates faster than the cylindrical bush 10.
- the angle B3, O1, B4, around which the cylinder liner 10 rotates, is thus greater than the rotation of the rotor 20 by the angle C3, O1, C4. Between the rotational positions of FIGS. 1 c and 1 d, the cylinder liner 10 thus rotates faster than the rotor 20.

- the cylinder liner 10 and the frame 12 are identical to the cylinder liner 10 and the frame 12 of the rotary piston machine of Fig. 2a formed and are therefore not explained again.
- a rotor 80 is accommodated, which differs only slightly from the rotor 20 of the rotary piston machine of Fig. 2, so that only the differences are explained.
- the rotor 80 has at its in Fig. 4a front end of a stub shaft 82 on which a first gear 84 can be rotatably attached.
- the stub shaft 82 extends through the lid 16 therethrough, is sealed against this, and the gear 84 is then rotatably mounted on the stub shaft 82.

- the first gear 84 and the second gear 90 are equal in size and have the same number of teeth and are interconnected by means of two intermediate gears 96 which are freely rotatably mounted on a bearing bar 98 or in a bearing cage.
- the two intermediate gears 96 provide for a connection of the first and the second gear 84, 90 and thereby for a synchronization of the rotational movement of the hub 86 and the rotor 80.
- the rotational movement of the cylinder liner 10 is then synchronized with the rotational movement of the hub 86 and rotor 80 and cylinder liner 10 are coupled together so that relative movement between cylinder liner and rotor 80 oscillates periodically between positive and negative rotational speeds.
- a gear mechanism that couples the frame 12, the rotor 80 and the cylinder liner 10 together thus consists of the connecting rod 94, which connects the pin 42 of the cylinder liner 10 with the pin 92 of the hub 86.

- the rotor 80 In the second rotary half, corresponding to the transition from the rotational position shown in FIG. 3c to the rotational position shown in FIG. 3d, the rotor 80 then rotates more slowly than the cylinder sleeve 10, since the angle A3, O2, A4 is smaller than the angle B3, O1, B4. As a result, the cylinder liner 10 and the rotor 80 move relative to each other, and that produces a relative movement between the cylinder liner 10 and the rotor 80, which periodically oscillates about a zero crossing between positive and negative rotational speed.
- first gear mechanism as shown in Fig. 4a and to arrange a second rotating mechanism on the opposite side of the cylinder liner 10 in order to reduce joint stresses and transmit higher torque.
