Air operating systems

John,
Were you able to solve your air issues?

Steve,

Jon Kabbe and I are going over to John Curwick's in the morning to take a look at what he has going on.

Sure, just hold your finger over the leak till I get there.

Jon and I cleaned and lubed the sequence valve to fix the potty. The 12VDC air pump had a faulty well pump switch which was replaced. The door is weird. It appears there is some sort of magnetic piece inside of the pneumatic cylinder that pulls the door open and closed. The door is smooth if moved by hand. You can feel something "clunk" inside the pneumatic cylinder. Do any of you know anything about this kind of cylinder? It is new to me.

I can see why Newell used this arrangement to allow the door to be forced open if there was no air present.

John has a problem with the compressor governor on the engine compressor causing a pretty good leak. That should be fixed before any more leak hunts.

Thanks for the feedback. Very nice gesture of you & Jon helping a fellow Guru!!!!!!!!!!!

My air doors are strictly an air cylinder.

I did a little reading last night. The cylinder is called a rodless magnetically coupled cylinder, and they are relatively common. You can see them in the McMaster Carr catalog.

Any advantage or disadvantage to this type as compared to the ones in our coaches?

Is John's repairable or does it have to be replaced?

Yes. You can break the magnetic coupling and force the door open in the case of being trapped.

I have the traditional rod cylinder too

RE: John's door: you also don't have to worry about getting injured by the door closing, it's a clever solution that I certainly would never have thought of. I've never seen anything like it.

Regarding repair, I believe the "repair" will consist of getting access to the inside of the tube and cleaning it thoroughly. Given the amount of water we observed in the air system I suspect it's just gunked up. A cleaning will be good for its soul.
