[SEL] Hit & Miss Engine Air Compressor Design Needed

[Curt]

Paul,
Enter Grainger p/n 3X818 on page
<http://www.grainger.com/Grainger/wwg/productIndex.shtml>

Unloader pilot valve is adjustable and will monitor tank pressure 
sending a high signal when pressure is reached. The old compressor you 
are using has a manual mechanical unloader I'm guessing. You can tie a 
small air cylinder to the mechanical unloader and let the 3X818 valve 
operate the small air cylinder on and off to unload and load the 
compressor.

Is it a Curtis compressor?

I have the old belt driven compressor and the engine but need some help designing the unit so that it will  unload at a certain high pressure and then load back up when the pressure drops to a set low point.
