309 sunroof?

Can someone explain how it works?

I mean, it deflates and inflates itself with no apparent powersource or
anything!

I think it's rather clever!

A deflatable sunroof? I've never seen one of those!

My 305 sunroof has the motor in the boot, if that's any help....

 

It's all done by vacuum, obviously. I think the tank is under the
scuttle next to the wiper motor, but I'm not sure. It gets its vacuum
from the servo pipe. I think it's designed to open and close five
times with the engine off. There's a couple of valves operated by the
sunroof handle which allow a vacuum in the seal to allow opening of
the sunroof, or open the seal to the atmosphere when the handle is
closed to seal the sunroof. Quite a clever design really and quite
reliable too. I believe it was only fitted to the 309.

 

works from vacuum pressure via the inlet manifold.

 

Wow, I never knew that. My 305 has air vents which open and close using air
pressure. I didn't know the 309 had a sunroof like it! Might have to look
into that system, as various parts of my motor-driven sunroof system keep
breaking.

My 1986 205 Gti had this as well. I don't know if it was standard on
205's, or if this was an option.

I had a 309 as well, and it's was definatly the same type of sunroof.

 

Got one on my 205 Dturbo!
My old 309 SRi had it as well. Greta nvention

 

Whaa! I want one now!

Methinks I might be off to the scrappy...

I didn't know that the 205 had it as well, but I'm not really
surprised. It WAS a good sunroof, simple and reliable.
