Rotary Lobes 24 - 25

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 25 teeth and another lobe has 24.
The teeth are abut at least in a line. Embed the mated lobes in an appropriate housing, 25 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 114 ul.
Smooth rotation and no jerk and shake phenomenon.
The unit may be embodied as a compressor, pump or engine.
