They are to keep the rain out, so are these for internal combustion engines? They would ‘strangle’ a chimney.

I've seen them on the model Holt engines with their vertical stak, seem to run fine with one.

Trick is to make the "cap" as light as possible and have the vertical part in your photo only just lighter so it counterbalances almost all the weight of the cap but still allows it to close.

They are an internal-combustion device. You see them, with or without the little counter-weights, on lorry exhausts that point vertically upwards above the cab roof.
