"To protect the blower from backfires? Just a WAG"

Sounds reasonable...BUT... I wouldn't be too happy about an air/fuel mixture blowing out there, particularly with an uninsulated spark plug wire next to it..... YIKES!!!

There isn't even a spark gauze.

What would Health and Safety have to say about that.

​I was at the Ellerslie Intermarque Concours ​in Auckland last weekend and had the opportunity to take a close look at a "1931 Blower Bentley".

There is a part of the engine that I cannot figure out and was wondering if anyone on the list who can shed some light on this.

Where the carburetors would be mounted on a non supercharged engine there are these very complicated devices.

I would guess that they are some sort of relief valve but, as the carbs are on the blower inlet I don't think that is very likely.

Anyone know?
