What is this Valve?

Can anyone tell me what this vacuum valve is called and its purpose? Maybe even a link to buy one online. I couldn't find it listed at www.rockauto.com .

Thanks...

Looks like a simple check valve, allows vacuum to flow only one way. Try checker or auto zone or a place like that.

Yes, that looks like a simple vac check valve.
But with the other end of the hose being connected to nothing, it's not doing much work...

I stopped at the Jeep dealership this morning and found out its hooked to and part of the Duty Cycle Evap Purge Valve PCM Output. How did I find this out you ask? They sure didn't know. They couldn't find the valve in their parts books either. Even better the Chrysler Rep was there and he had no idea what it was or where to find it. I asked to look at their book and I found what I just told you about it. Not much info on it. Reason I asked is thats the only thing missing after I changed Engines and thought maybe it had something to do with my idle surging from 400 to 1400 and back and forth.
Hell, I've tried everything else.

Thanks...

Back in the day I had a Honda that did that after I worked on the cooling system. I didn't completely bleed out all the air causing to idle like you mentioned. Don't know if the V8 Jeeps have this trait. I did my 4.0's system in the winter and there was no bleed valve to be found.
