The invention relates to a rotary machine with eccentric piston, that can be a pump, compressor, pneumatic motor, hydraulic motor or internal combustion engine. According to the invention, the rotary machine has a cylindrical piston (1) mounted in a cylindrical housing (2) tangent to the inner cylindrical wall of the cylindrical housing (2), the cylindrical piston (1) being provided with a sealing piece (3), wherein a rotary blade (4) can glide, said blade being integral with a driving shaft (5 ) whose rotation axis concides with the axis of the cylindrical housing (2), the rotary blade (4) being in permanent contact with the inner cylindrical wall of the cylindrical housing (2); between the rotation axis of the cylindrical piston (1) and the axis of the cylindrical housing (2) there is provided an eccentricity (e).

The pump can be used for oil extraction.
It is more efficient and can extract oil at lower costs than current extraction pumps.

Why?: what losses are there in a conventional reciprocating or rotary pump that are reduced in this design and why is this the case? And what fluids would this pump be good at pumping into the reservoir.

Positive displacement vs centrifugal pumps: https://www.castlepumps.com/info-hub/positive-displacement-vs-centrifugal-pumps

The pump with a rotary piston has the efficiency of a piston pump but it rotates so, It does not require this mechanical drive.

It resembles the rotary positive displacement pump https://en.wikipedia.org/wiki/Pump#Positive_displacement_pumps

but it is greatly improved. The pallet is tied to the spindle and the pallet does not need to rub the stator.


But.... we can use an assembly of a hydraulic motor with a hydraulic pump.
We supply with water to the hydraulic engine, which receives water at the pressure depending on the depth of the drill well.
With the mechanical work done by the hydraulic motor we operate the pump!

My question is: why is this posted?

The OP is not asking any questions, just showing his work and laurels.

Which is OK, I guess, but maybe more suited to a blog?

Do you have any question or opinion about the rotary piston?
What do you think abouta hydraulic torque transmission?

So you just trolling.

I am not trolling.

You posted some stuff, but ask no questions. That is unusual.

Don't get me wrong, you've done some great work, and are to be commended for it - my question was not intended to criticize what you've accomplished.

I'm ready to discuss anything about the rotary piston.
Introducing other topics for discussion I consider trolling.

So, what do you think abouta hydraulic torque transmission?
 
Emil:

I assume that you've had lots of interest and investors in this since 2009.

Is that correct?

Ah. So you propose to put a pump and hydraulic motor assembly down a well and pump oil to the surface that way. Or you could use an electric drive, which is probably easier.

But like billvon, I am not sure you have invented anything new here. Look at this for instance: https://www.psgdover.com/en/technology/positive-displacement-pumps/eccentric-disc-pumps

This seems to be your invention. Tell me, is the patent document you linked to a granted patent or just a published patent application? It is normal for patent offices to publish the application, so that interested parties can raise any objections before it is granted. The prior art search sometimes goes on after publication. To be honest I would be surprised if a patent is granted, as it looks to me as if it has been anticipated by existing designs.

Yes, this eccentric disk pump is very good!
Yes, the patent is granted starting January 30, 2009.
The patent application was made on October 26, 2006.
It is also the Europeana database. https://www.europeana.eu/portal/en/record/2020801/dmglib_handler_image_9117023.html

I see that Excentric Disc Pump is from 2012 ...
 
i once owned a Mazda Rx4 which had a rotary engine. Are we talking about the same principle?
