Knitel's InfinityPump

Hi Guys,

Here is some more on my ideas for this pump. I moved the V3B valve out into a separate pipe. The top end is parallel to the V1 valve and line but is separate from it. This allows the water to flow from the top to the bottom while the piston is rising without compromising the integrity of the air bubble under the piston. When the piston rises above the V1 & V3B lines, the valve at V4 opens to let the air from the previous cycle exhaust out. Once the piston rises to the top of the stroke, V4 closes and V3 opens to let the trapped bubble escape. V3 then closes V1 opens and the weight of the piston forces the water down drawing more water in from the reservoir. At the bottom, the piston fills with air again, V2 closes and V3B opens, the piston can rise back up to the top until it again forces the air from the last cycle out through V4. Cycle complete.

PS. I'm not a professional in either physics or hydraulics, but I have had a lot of experience with aquariums over the years and I think I understand syphons pretty good. I've drawn a measurement (A &B) on the pic below. This represents the pressure differential that needs to be overcome by the difference in buoyancy of the piston. Its not the whole length of the riser tube, its only the difference between the intake and the outlet.

onevoice... wolud be nice if you could make complete animation, although I understand how it should work - animation could help to find obstacles.

the animation I ment one should build on is (wrong link before)

This is when looking it again very inovative approach now floater has better chance to still be bouyant, if it must be heavy for pump up action in the first place, cause it has
now additional air bubble. this is very very close to be understandeable concept - and overcome(overweight) pressure from hidrostatic paradox and still be able to make floater
LTW lighter then water.

can you please make an animation
this is fantastic contribution, if someone could make another such finess change, this pump would be way stronger so paradox can not stop it.

if V3B opens when floater-swimmer is at the bottom - how is water pumped up ?

@ onevoice,

The trouble with your design is the top valve that supposedly lets the trapped air out. The only way to expel the air is to fill the void with  water. How can a void that sits above the syphon be filled with water?

Hi Igor,

Thanks for the link(s). Will study them after my kids go to be tonight. Would watch out for the inflatable seal because its size will vary with depth. Leak at the bottom and too tight at the top. Lots of questions, will try to answer:

Igor: I'd love to make an animation, but I'm not technical in physics. I don't think the key is so much to make the float between density of air at STP vs water so much as it is to be able to alter the displacement of the piston. To make it as heavy as possible at the top and to make it as light as possible at the bottom while using less energy then can be gained by the potential energy of the water movement. Any suggestion for simple animation s/w I can learn on...PS Must be cheap or free too!

if V3B opens when floater-swimmer is at the bottom - how is water pumped up ?

A: When the piston goes down, it should be dragging the water in through the intake so the space above it is already full. Yup, I agree, the'res going to need to be some small space so the water can come in under the piston through the V3B pipe.

The trouble with your design is the top valve that supposedly lets the trapped air out. The only way to expel the air is to fill the void with  water. How can a void that sits above the syphon be filled with water?

Hans, there are two things that 'could' fill the void. One is water, the other is the mass of piston itself. Think of it like an internal combustion engine. On each downstroke, air enters the system below the piston. The added buoyancy drives the piston up but it must also release the trapped air from the last cycle as an exhaust out the top. Once the exhaust has been cleared, the top valve closes and the V3 valve opens in the piston, releasing a new cycle of trapped air. Knitel has a great idea here, I'm just working out details. Here, a new pic. Notice the outlet at V2 can be slightly higher than the top of the lower outlet at V3B. So long as the V3B valve is closed, air can't get into the tube and water can't get out

One other thing that's good about the top air exhaust is that any small air leaks in the system will naturally rise to the top and get purged from the system.
