Male/Female Coupling at A/C Drier

[armcallister]

While replacing all of the A/C components in my '87 Comanche I removed the Male/Female coupling adapter from the old dryer to install in the new one.  One of the spring loaded internal components dropped out and I want to make sure I re-assembly this correctly.  The attach photo is the orientation I believe the internals should be in but would appreciate confirmation or info on the correct way these should be installed.  Also, other than being a Male/Female adapter, what is the purpose of this fitting and it's internals?

 

Thanks!

I received a photo from the Renix FB group showing the left hand side of the coupling and it appears I have the orientation correct.  That is the side that attaches to the hose assembly.  I still need a pic or verification on the right hand side.  The right side attaches to the drier.

this help?

Thanks, Pete, but what I am needing is the orientation of the internal, spring loaded piece that is inside the coupling attached to the drier.  I was hoping someone might have one laying around the shop.  A pic of either end of that piece that is attached to the drier is all I need.

 

Thanks

I'd say your guess was correct.   finally found the old one from the 88 in the driveway.

Thanks, Pete.  Exactly what I needed!

I understand that it’s a check valve but why is it needed? I work on a lot of E-series Fords and most of that is ac work. Granted they’re orifice tube systems and not TXV systems but I’ve never seen a check valve like that in them. Not even on the rear auxiliary systems that use a TXV. What purpose does it serve other than “checking” and “valving”? I ask because I recently went through my ac and replaced all of the o rings and there was one on that valve that almost seemed molded into it. It was torn and I couldn’t find one that would fit it. I have a metric fecal ton of various sized o rings and nothing would match up. Could I just eliminate this valve?
