Air Tire Pump

This Instructable is mainly made of scrap materials and cost me about $20 Australian dollars from my local bloke hardware for those 'few extra bits'.

The principle of this design is a tyre is used as the bladder and this is moved up and down via a crank (hand driven in my case with the option to be driven by motor). Air is directed through the tire using simple one way valves, as the tire is raised and expanded mechanicly air is drawn thru the one way valves (intake side),into the tyre.
Then as the crank forces the tyre to a squashed postion the air is forced through the bottom one-way valve and to your piping.

Uses for this project could include: air for a foundry, aerating water, filling balloons, pumping water ect.

With this re- use of a tyre, you could scale it both ways and get great results, e.g. a small model aeroplane tyre hooked up to a 12v motor would be a great fish tank oxygenator or a larger truck tyre version could keep an aquaculture company aerated.

Those willing to change the valves around could also pump water.

Also if you are going to put this into long term use I recommend using proper bushing and bearing techniques, as I have not designed this one to be used for long.

Step 1 Things you need

THINGS YOU NEED
Tyre and inner tube, Wheel barrow wheel in my model.
bolts out of your own collection or local shop,
suitable hose connector, to suit your piping

Steel tube 75mm x 38mm approx 2.5 meters ,
rivets and washers to suit,
silicon sealant,
70mm I.D pipe (50mm long)

PARTS YOU WILL MAKE
Base, Five anchor pionts, At least three valves, Rocker arm, Crank (optional motor drive), Air chamber, Two tyre anchor plates.

TOOLS
Welder / or tech screws if you want to do it  differently,
drill,
file,
cardbaord,
grinder,
spanners,
20mm reduced shank drill
12mm drill
Clamp

Good job.

[littlebuddha4]

very cool i think putting a bike on it for pumping water up the hill air is a great mover of water

[heimo]

very cool I am thinking of a motorized version thanks for the insperation

[FeedTheGrid]

You got my vote. Very cool, Johhny; and educational. I'm not sure if I grasp how the one way valves were made though. FTG

Hello FeedTheGrid, I have done some editing of the valve section with some explanations and notes on pictures. I would love to draw what I am explaining or make a .GIF but not sure how (I know just search it). Thank you very much for your vote

[FeedTheGrid]

Now I see. Thanks. Nice work.

Nice work John, I could see this in a third world country that has no power available and use it for pumping water, I see so many people carrying buckets from the river bank or well, this could be submerged just under the water and crank away to deliver the liquid to a storage tank or piped over small distance, Well done lad, Regards Steve

Brilliant!

I like it! I might scale it down sometime along with a small windmill for power.

[Johhny]

Thats a good green idea. My next one will be small, and a replacement for my aging (noisy) fish tank pump. More valves or larger ones so the tyre can breathe easier will make turning the shaft easier in lighter winds.

Similar design I saw in the book Design for the Real World by Victor Papanek. It was published in 1973 in the USA. It was supposed to be used as an irrigation pump in Africa.

Yes it is not an original, we have some people using car tyres to aerate marron ponds, and I think a local mine is using D9 haulpack tires in there ponds.
