Hi Igor,
yes, this new animation should also work very good !

Brilliant, Well done !

Regards, Stefan.

hi all,

you make it sound like this heavy weight will float on the surface of the water.  it won't!  it will displace water (make a hole) and set inside (not sink).  to do this it needs to displace more water than it weights.  this much water has volume.  1 cubic inch weights .036127 lbs.  how many cubic inches will it take to weight the same  (really more) than your weight?  since the disk only has so much area, you have to gain the rest in depth.  any clearer now?

P.S:. Igor,you can also use 2 x V2 valves at the bottom, so the air will come easier
into the lower water cylinder in your new animation.

You could also even open the hole lower cylinder plate until
the lower water has all flown out.

There is no sifoning effect ?? Where do You see it ?
You forgot to enter in calculation that input pipe has much smaller diameter than cilinder ...why ?

if there is no syphoning effect, how is the water moved from lower to higher?  you are doing the same thing as syphoning.  the difference is you have replaced the longer end of the hose which has more weight (water) which causes the transfer, with a lesser volume weight.  the force is still there to draw the water up.

input pipe can be any size diameter.  as long as you have enough weight to move 1 square unit, you can raise the column of all square units.  to compare, think of a syphon hose.  it is the same diameter for its total length.

i think everyone (like me long ago) thinks the large weight applies its force to the small tube.  it doesn't unless the tube is as large as the cylinder.  even then it is spread evenly over the total area of the disk.  that is why you have to figure the weight of a column (sq.in., cm2, etc.) not total tube.  if you have a disk surface area larger than the input tube area, the extra weight is applied to the top of the closed cylinder (not used by input tube).  after all, gravity's force is only down, not side ways.

i'm sure i have said things here that you can't believe.  that is why hans said to study.

Third

Siphon, no

Mechanical suction yes[upside down bicycle pump]

If the big weight displaces more than the pick up tube

The weight will not stay up,and will suck [not siphon] water from the tank below
