Can someone please explain what the parts high-lighted in yellow do. The S30 parts illustrations I have (attached) dont show these extra parts. Please post any illustrations if you have one. Thanks in advance.

More specifically, it is part of the Anti Backfire (AB) Valve and associated system.

Can be discarded in the UK.

Edited to add: It's one of the reasons people seek out the 'clean' Euro/UK balance tubes. Less tacked-on gubbins.
