I was curious how it was driven. Did you find out the physical size of the unit ?The roots blower idea has nothing to do with rising cylinder pressure like what is was designed for on a normal eng.
It has to do with controlling flow threw the 2 stroke eng at all times.
Marinating the same case flow and press profile in one revaluation at all RPM's.
It would be mechanically attached to the crank.
No more suck and blow...........no more trying to suck every last drop out of the case with the pipe.
Timings and pipe design would have to change to take advantage of it.
Scavenging and port lay out would take a whole different look.
Get on it !Now imagine replacing the drum intake valve with this kind of pump????????
Some day when I do not have to wake up and listen to my ass hole boss bark at me and all the 12 year old girl union line men whine at me I will.Get on it !
Hang in thereI GOT IT!!!!!!
New T shirt I will make.
Why suck and puke when you can blow.
Check out this set up.A Roots blower is very inefficient at any but the lowers pressures. Today, screw type compressors are usually used for the larger air compressors as well as for superchargers in cars. See Twin Screw vs. Roots | Kenne Bell

Now that look very interesting.Vane compressors also have internal compression. Small roots or screw compressors have large leak paths in small sizes compared to vanes, but vanes have higher friction losses. The third type of compressor that I think would be useful is the liquid sealed compressor originally made by Nash. Fuel could be the liquid with a metered amount joining the air into the engine. These are the easiest pumps to build and require almost no precision except at the seal face. It only needs to be flat with a low clearance set by shims. I've rebuilt the vacuum pumps in my office several times. Swirling the liquid does create drag, but the seal is close to perfect. It would be easy to build one in model sizes that would work at our engine rpms.
