Rotary Lobes 2 - 3

Here is offered a rotary mechanism .This mechanism inclusive two dentate lobes which are created from a solid orb body.
These two lobes are mated with a unique angle. The number of teeth on the lobes are differ by one. In this art one lobe has 3 teeth and another lobe has 2.
The teeth are abut at least in a line. Embed the mated lobes in an appropriate housing, 3 cells are created. While the intern engaged lobes rotating around their axis, the instantaneous abut lines do not expire in the hole of rotation and teeth-cells act as rotating piston-cylinder.

Advantages

Providing positive displacement unit.
The ratio of DDC on TDC volume is about 2000 ul.
Smooth rotation and no jerk and shake phenomenon.
The unit may be embodied as a compressor, pump or engine.
