You are close- I may be slightly off as well, but this is what I have been told and what I have seen.
The dial regulates the pressure on the membrane in the automatic control. One hose goes to the bag chamber, one to the hose inlet, and the third hose goes over to the bellows that opens the chamber.

Its actually a very simple system. It works on a difference in suction pressure. When the pressure at the back of the bag compartment (aka - right off the motor) is the same as the pressure at the front (aka the hose connection) everything is ballanced. As the bag fills suction drops at the hose end and an imballance is created. When the imballance is sufficient enough it sucks down the bellows which activates, either the latch, releasing the front cover on older models. Which then, in turn, turns the machine off or, in newer models, it simply moves a switch which turns the machine off. The controll dial merely regulates the tension put on a diaphram spring which, in turn makes it harder or easier for the diaphram to operate (eg - requireing more or less of an imballance of suction to activate )
hope that makes sense. Doug | ||

Thanks for the replies. What a neat system, I figured as much it would measure the difference in pressure from the front to the back, but I wasn't sure. Too bad the Diplomat LX won't open up when the bag is full lol. | ||

Christopher...You have.... 400 vacuums?? Wow...Where do you keep them all? I am very curious. Would it be possible to post some piks of your collection? thanks, Brad. | ||

I've never had any clue what the cordwinder to bag chamber tube was from. I do know that it really doesn't change anything if you remove it- unless someone knows differently.
Beerad- I'll just send some pictures of the sheds...we are slowly going through all of the crap and trashing bits and pieces. Most of them are random 70s and 80s machines that we rob parts off of. Consider about 100 of those in-stock units for sale as well (I guess those shouldn't be considered "collection" machines) Crevicetool- Are you my Buckeye rep by any chance? | ||

That makes a lot of sense Hans. I guess it is a tiny, tiny stream of air. When we do a basic service and cleaning on a Lux for a customer, the motor gets blown out, but not removed- so we never re-connect the hose going to the cordwinder seeing as how that would take extra time to remove the motor, etc. I haven't had one come back with a cordwinder melting!

Doug and Christopher, I think this is what you are thinking of. I know this is what Doug is at least. This is on the AP280. Funny how its routed this way, and on my Diplomat LX its piped through the bottom of the bag door on the hinge.

That makes perfect sense. I would imagine because of the compact size of the front dover on the Diplomat and for cheaper manufacturing reasons, they decided to disregard the original design. I wonder how much research and development it took to begin this system and perfect it as Electrolux did.
Just a tip for many people- before replacing the whole assembly if you have a door that keeps popping open, take a small wire and clean out the hose that terminates at the vacuum hose inlet. This has saved much time while doing a repair on one that keeps malfunctioning. | ||

I've always wondered about Electrolux's R&D in general. Some of the designs, features, and way the machine is built is just pure genius. | ||
