Hi, all pneumatics fans,

For some time I've been trying to figure out how to objectively compare
the performance of the various air compressor designs especially the
ones using the large pneumatic hand pump which seem to be coming into
fashion lately.

After much thought and several failed attempts, I've come up with an RCX
Controlled Air Compressor Tester. The details and test results on a
number of the commonly air compressor designs are presented at:

I believe there is need for a re-think on air compressor designs.

Your friendly critique and comments are most welcome.

Hi Chio
   Thats a pretty interesting design. Nice work!

Here is a link to some pictures of the two stage compressor I built. Hopefully
there are enough details shown to reconstruct it but if you have any questions
let me know. The actual compressor assembly is fairly compact and a drive line
could be designed in other ways but I wanted to have the motor and compressor
in a compact unit to insert into various models. After seeing your test
results, I added the extra gear ratio to increase the pump speed. Using the
belts allows the drive to slip when maximum pressure is reached. The chain
drive will only operate smoothly when the motor is turning clockwise.
well, let me know what you think : )

Why is this two stage? I could not follow this design clearly but are you feeding the output of one stage to the input of the next? Two compressor pistons in parallel is something else (double acting?? I am not sure what)... Cool design no mater (...)

(...) My, that is an awesome looking compressor design, indeed. I hope it doesn't throw my recording device off-scale. I'm not too sure I can build it just from the pictures but I'll give it a go. It'll help if you could include some exploded views (...) (25 years ago, 30-Sep-99, to lugnet.robotics, lugnet.build, lugnet.robotics.rcx)
