- the invention relates to a device with at least two rotating pistons revolving in an annular space Circulation direction forward an expansion chamber in the annulus and limit the rear, with the rotary pistons over a Gear arrangement with a common torque transmission shaft connected that the volume of the expansion chamber alternately reduced in size and enlarged.
- a device of the type described above can be used both as Pump as well as an internal combustion engine.
- An internal combustion engine with a rotary piston is a Wankel engine known. With a Wankel engine, the expansion takes place Expansion chamber not only in the direction of rotation of the rotary piston around the output shaft, but also in this vertical, radial direction. To get you relative movement of the Rotating piston to the combustion housing surrounding it control is a complex gear transmission between the Rotary pistons and the output shaft required.
- a device designed as an internal combustion engine described type, in which the expansion chamber in advantageously only by moving the rotary piston in Direction of rotation reduced and enlarged, is from DE 42 26 629 A1 known.
- the gear arrangement has a large number connecting rods supported on a cam disc. The load on the individual connecting rods occurring in this arrangement and their articulations also due to the friction on the Cam disc does not leave a long life of the known Expect device. Nor is it realistic that known device for the application of high torques to train a large displacement of the expansion chambers.
- the gear arrangement has a planetary gear and several handlebars and cranks between the Rotary piston and the torque transmission shaft.
- the Gear arrangement is relatively complicated. So prepare it Difficulty with a device with relatively little effort to realize that for large torques over long service lives is suitable.
- the invention has for its object a device Point out the type described above, in which the gear arrangement for alternately reducing and enlarging the Expansion chamber in the direction of rotation as simple as possible is built to be powerful with little effort To be able to implement devices.
- this object is achieved in that the Gear arrangement between the torque transmission shaft and at least one of the rotary pistons at least one kinked and not in terms of its cyclic rotational phase shift has compensated universal joint.

- At least one universal joint can be the resulting Rotation phase shift and thus the maximum relative movement of the two rotary pistons can be changed. As a result this means that the compression of the expansion chamber between the rotary piston is changed. So the compression of the Expansion chamber adapted to different operating conditions without the construction of the entire device needs to be changed.
- the new device can be used regardless of the number of Expansion chambers can be designed as a pump.
- the device in another Embodiment is the device as an internal combustion engine educated.
- feed and Discharge openings to the expansion chamber or are provided be a significant expansion in the circumferential direction of the Have rotary pistons in the annulus if not reached that one of the two rotary pistons is almost at rest when the other rotary piston approaches or moved away from him. This can be achieved with at least four kinked and not compensated universal joints between each the rotary piston and the torque transmission shaft.
