Why are pumps cylinders and pistons round?

Would pump more air per stroke if they were both "square" :D
Would also make the "flat" base much happier :heartface: :love1:

... maybe the same reason air compressor or auto engine cylinders have been circular for a century or longer. I bet it would be a bitch to make piston rings or seals with four, or more, hard-angle corners.

... Supa, Make one. Just do not get suckered by TV commercials into applying for a patent.. make it work first. Good luck.

OK, I'll bite.

Easier to machine, no issues with misalignment (particularly misalignment of gaskets), ability to twist the handle without compromising the pump, no corners gouging the inside of the cylinder.

I want to buy one.
If it's not built yet, I will pre-order so I can be the first to have one.

My only questions is will I have to change the valves on my kite to square ones?
If so, send those too!

Thanks,

I like it!! Just like square Hamburgers, they have a place!! A beavers tail is flat and what if it were more square? Hmmmm?? Faster swimming, moving more water around when Damming up the place??

Well said and great idea to have square intake valve "and" also square pump hose & nozzle !!
Even the "dump valve square" to get air out faster!

BTW not intended as serious post (although it would speed things up to get out there)
Simply poking little fun at "why pump bases are flat?"
Isn't it still hip :cool2: to be square??

Oval? In the past, if I'm not wrong, top level motorbikes used oval cylinders.
