Cadman’s Hydrostatic Displacement Engine

[Grumage]

@Floor since you grasp Grumage latest concept could you draw a cyclic diagram of that concept? I think many would struggle with all the textual descriptions here. I can even do an 3d animation if needed but need to understand it better first.

Dear broli.

I'll try to explain concept 2 verbally again, my drawing abilities are very limited in this modern age. When I was taught it was with paper and pens.       Your offer of 3D sounds wonderful, bravo.

My single drawing shows the device at rest with water from the upper cistern piped down to the underside of the bellows/concertina, admission valve closed.

Upon opening of the admission valve the water fills the bellows causing it to rise ( transfer valve is shut ) we have allowed it to rise by 150mm or 6" lifting the displacement cylinder vertically through a sliding seal in the centre of the cistern 2 meters above.

We close the admission valve and open the transfer valve. The combined weight of the " bias " and cylinder now causes the water to flow into the displacement cylinder and travel upward round the sides of the solid Steel displacer piston. The bellows have now returned to rest as in my picture.

The next upward stroke see's the bellows fill and rise again, as we have 75Lbs of force available acting against just the volume of water plus that of the bias and cylinder. The displacer which is rigidly fixed from above the device, displaces the water through a cup washer at the top.

We now open the transfer valve and the bellows and cylinder collapse once again. As the cylinder collapses any water above the displacer piston falls over the sides to refill the cistern.

Back at rest again and ready for the next cycle.

For an automatic reciprocating engine we shall have to design some mechanism to operate the two valves.

But....

This all seems far too easy, what has been missed, am I dreaming?

Cheers Graham.

Addendum.

I forgot to mention that the fixed displacement piston is of high density ( Steel ) that has a diameter of 1/2" ( 12mm ) and is solid. The water flows around the 1/8" 3mm gap via displacement. A simple Leather cup washer ( bicycle pump style ) is fitted at the top so that on the upstroke the water can pass by it easily but is then held in suspension and just flows over the edge of the cylinder wall on the return stroke. Refilling the cistern.

Cheers Graham.

Thanks Grumage, wasn't totally sure.

@all readers
   One more proof / drawing, below. The last of that part of my endeavor
             see the  "floor Cadman 3F-10n.PDF"

@Broil
  Yes I will do a flow diagram.  But don't jump on the 3d until
I have made certain with Grumage that my interpretations are correct.

    thanks

Hello All.

I felt that perhaps my description of operation was lacking one detail, I'd forgotten to mention that the system had been previously purged of any air.

Sorry for any inconvenience.

Cheers Graham.

Although the proofs I presented come at Cadman's design in a sort of backwards and upside down
manner, they definitely verify his design as being able to use gravity as an energy source.

Here is my summation.

You want O.U.

Cadman's design is a go.

Study and understand it, and you will see this for your self.
