Unloader valve

by Buddy Wommack

Bill, My compressor has an unloading valve that ends up on a circular device on the opposite end of the crankshaft from the drive pulley. I have see them going to the pressure switch, but this is a different setup and I do not understand how it works. Can you help?

Not without knowing the make and model, and seeing a photo or two of the unloader, Buddy.

Please start a new thread - then you can upload up to 4 photos - and refer to this one, and I'll put them together.
