Hi Guys,

I've often said that I can't find stuff ! Well this morning I was looking for some bits and bobs and came across this gadget. I don't remember exactly when I acquired this device. Probably many years ago when I was young and foolish and into cars and bikes. Anyway I thought that it was interesting and you might like to see one.

This is the complete device. Then with the top valve removed. Under those slots is a second rubber flap valve allowing air to be sucked in. The pictures below are of the non return valve. Which is a simple rubber disc under a brass screw with a hole in it.
The rubber disc just oscillates up and down in use. Allowing air and any petrol vaper to be compressed into your tires !

The last picture shows that it was made by "Pneumatic Components Ltd" Sheffield England.
