Dial adjustment makes no difference- I left that out of my previous post, sorry. 'Tis a puzzlement! |

There was some, but I cleaned it out earlier tonight, and no change. |

I concur with Rick. Usually that problem was caused by the diaphram connetion in the throat being plugged. We used to take the plastic hose off it then use a pin to clean it out. (Yes - I was an Electrolux service tec for 10 years). The release is actuated by a difference in pressure between the sides of the diaphram - one side is connected behind the bag the other infront of it to the throat. If the front one gets clogged it actuates it.

Mmm, good sketch and a great question. I'm looking forward to the definitve answer. I have only hands-on experience with LXs and the next generation of metal body Electrolux auto door system. All of these have a one piece brass tube with a closed end that has a teensy bleed hole, smaller than the average dressmakers pin, drilled through the closed end.1 Meaning smaller than 1/64". No inserted plug. I have worked on LX, E, AE, G etc bleed nipples that were dust impacted reducing the size of the bleed to a hair's width, or completely plugged. My AP100, which works and pops open as designed, has an all plastic bag door with the powerhose socket and bleed tube nipple an integral part of the casting. It has a just under 1/32" bleed hole drilled through the plastic nipple. It's my suspicion that the bleed hole can't be any larger than this and allow the system to function reliably. The pinhole sized bleed lets the latch diaphram collapse slowly as suction is reduced - a bleed as large as 1/8" would cause the diaphram to collapse imediately, defeating the purpose. So, maybe that is a gray plastic plug. Pokeing it with a needle will soon cause it to disintegrate if it is impacted dust. If not, it's a plug. As I say, I have no direct knowledge of the later American versions of the Canadian AP100, which was introduced here in 1973. Dave, always interested in engineering analysis. |
