News: “Over the graves of the Druids and under the wreck of Rome,
Rudely but surely they bedded the plinth of the days to come.
Behind the feet of the Legions and before the Norseman’s ire
Rudely but greatly begat they the framing of State and Shire
Rudely but deeply they laboured, and their labour stand till now.
If we trace on ancient headlands the twist of their eight-ox plough.”

-Rudyard Kipling

1, Water flow shuts valve.
2, Water is not compressible so forces some into air chamber through non-return valve.
3, Air is compressible and forces water up delivery pipe.
4, Valve at front of pump opens when pressure is released.
5, return to 1.

That is as simple as I can make it. Have a look at the attachment in the last post as it shows several good cutaway drawings of these wonderful, simple machines.

I've seen a few of these before, and have tried to understand how they work.

Anyone care to explain in short sentences?
