Rotary machine Piston Ring Tri Lobique

[Pascal HA PHAM]

Hello,
another kind of industrial archeology ... more personal & much more modest this time,
I found my first patent filed on June 13, 1977, at the age of 24 ½, on behalf of the RENAULT factories. In 1978 the RENAULT agency extended the patent to Europe, then to the USA, CANADA & finally to all industrialized nations, hey hey, even if it's old, it's set in stone.
The invention equipped all the R18 produced by RENAULT in the world between 1978 and 1995, 2 028 964 cars. The fixed bonus granted to me for the invention was at the time of 1200,00 F, or about 681 €. Here are some emblematic traces of the patent:








"Free of prior art" of course!

it will soon be 38 years

A + friends, wait a little bit: I have some rather cool novelties in cogitations.

"If you do things right, sooner or later things will happen to you right ... if you do them wrong ... the reverse will also be true"

Hi Pascal,

Beautiful retrospective!

And for the future? TVEMGC is honored in the sycamore video of november

Thank you Raymond,

Hello everyone,
After a long month of silence (over a year!), This is an opportunity to make a point.
There is a reason for this silence: the EMGC machine is the subject of contractual studies via some French grandes écoles and the file is also the subject of a contract with a private company .... so shutt. ... let things evolve confidentially and with confidence.

Prototypes have been made at the 1 / 5 scale .... I am at the N ° 3 version of improvements.

I can therefore reveal the 1 version of the proto without violating the confidentiality contracts that bind me with my associates.











Here it is: following the backing with a private high tech machining company, I am able to produce "EMGC" type parts assembled with operating clearances of the order of a micron.

A small video was made to illustrate the cycled functioning of variable compression, this variable compression is one of the prime assets of the concept.
I will post you soon the clip ... promised!



See you soon

I have the impression to see remakes of the Wankel Engine.
This one was finally abandoned: problems of tightness difficult to solve, that one does not have with the segmentation in the classic engines, and of high consumption. Would technical progress allow us to return to such attractive ideas?

Hello,
This new concept is very different from the WANKEL in more ways than one, as evidenced by this summary. Some pictures of the volumetric variations modules illustrate the thing, the patent of EMGC, free of prior art, confirms the fundamental differences that sets it apart. WANKEL rotary machines.

Three volumetric turbine modules with variable compression (the training modules are not exposed)
On the right are two early EMGC 41 cm3 demonstrator prototypes (1 / 5 scale) .... and on the left the new EMC 2P 2C 500 cm3 prototype (1 / 2 scale).
THE COMPRESSOR HYPER BAR AND MEGA DEBIT

" what is that thing ? "

It is the rotary pistons / cylinders part of a new volumetric turbine type machine for compressing sensitive gases at very high pressure.

"Why this challenge? "

With equal weight one kilo of gaseous hydrogen contains almost 3 times more energy than a kg of gasoline or gas oil ..... and when consumed in a fuel cell it only releases water . There is however a big problem because 1 kg of gaseous hydrogen at atmospheric pressure "normal" occupies near 12 M3! and a medium-sized hydrogen car consumes 1 kg at 100 km ... imagine a bit to perform 600 km it would take a 72 M3 tank! it's impossible. Toyota then Honda, then the German manufacturer now manage to control the manufacture of tanks of 150 liters containing 6 kg = then it is necessary to compress the gas to more than 750 bars ..... no current compressor manages to do it properly .. ..this is why I imagined this patented invention.

THE CONCLUSION IN ITS CONTEXT:

I study this machine in its version compressor dihydrogen (gas). the challenge is to be able to inflate to 750 bars the tank of a future ecological car 100% electric equipped with a fuel cell, and to give it 600 kms of autonomy.

"750 bars, ... 600 km of autonomy ... It's very strong. Are there any competitors? "

American standards have already set the maximum time to fill up 6 kg - 150 liters of H2 to 750 bars - 150 seconds - or the full 2 minutes and a half
Under these conditions nobody can fill the tank properly in less than 3 minutes and in a just-in-time flow (from 80 bars to 750 bars) all the compressor manufacturers on the planet are on the spot and can only manage very wrong.

Note: 80 bars is the minimum pressure for the transport of sensitive gases in existing pipelines.

The organization of the variable compression would / seems just as interesting and suited to traditional external combustion engines and internal combustion, but that's another story .... and it will be for later.

"So it's a hyper-strategic issue for two reasons? "

Yes ... but the public authorities seem to ignore it.

NOTE 1: A WANKEL does not have the fundamental characteristics to satisfy / be eligible for the challenge of variable compression HYPERBAR MEGA DEBIT
NOTE 2: for reasons of confidentiality that bind me with associates I would not communicate - for now - the exact nature of the evolutionary profiles of my latest machines.

Hello everyone,
Go some news!
some quick pictures of the "EMC 2P 2C" machine drive system.
the particularity of the concept of this new volumetric machine is its variable compression in full operation / full load.
The said analog training is designed as follows:
by analogy with a railroad, you wind the rails on a drum = it becomes a barrel, then you guide this drum / barrel in rapid rotation by 3 pairs of wagon wheels whose axes are set at 120 °.
the axes and spacers of the "flying" barrel will then drive the perforated rods of the central volumetric module.
Variable compression is performed by lateral and relative sliding of the 2 modules.
The machine at the 1 / 2 scale then makes it possible to go from a zero compression ratio to an extremely high compression ratio without interrupting the operation.

Currently my prototype is 500 cm3 and it is almost complete.

I meticulously test all the elements and modules,
one by one, before final assembly ..... and tests.

the current drive module = designed to turn quickly (very quickly) at an almost stable speed .... with a central "floating" drive barrel which is more than 300 mm in diameter

the current volumetric module = 500 cm3

some elements in spare parts

are still missing the slides that allow to receive the one and the other of the modules and the few essential parts to the controls of the machine.

back to 2007:

: Idea:
first idea ..
HI .... ! "She is the fist sister of the TRI LOBIQUE":
here is the "TP GEO" or Multipurpose Turbine with windows in opposite states. Patent application filed with the INPI PARIS the 12 / 11 / 2007 under the 07 N ° 07904.
The Disclosure and Operation Authority arrived yesterday is dated 28 / 11 / 2007.

Hello,
After a few 9 years of waiting .... to such an extent that I no longer believed, the INPI has allowed me to review the claims of my patent 07 07904, including act.
And the inventive character is finally recognized.
This gave me wings to start building a working prototype in the autumn 2016.
As the pictures show, this prototype is practically finished.

quick overview of the features of this early machine directly from the 2007 end patented concept:

HYDROLIENNE "TPGEOP"?
New prototype! YES!
It is almost finished!
only the cam and its control levers are still machining.

It is all aluminum, stainless steel and bronze to work immersed in seawater, the bearings are also INOX

60 cm of wingspan
8,5 kg of rotating mass
The control cam and its 2 lateral levers are still missing in order to pull / push the 2 mobile grilles cyclically.
dynamic balancing is OK up to 500 rpm.

IT IS DEDICATED TO THE HYDROLIEN ..... to be implanted in deep water to exploit for example the currents of GULF STREAM

but .... since it is very solid ....
And I also think of turning it under relative winds of 30 m / s and more if affinity (fixing the supports on the roof bars of my car).

oup's .... I forgot
the patent :

with a few complementary drawings:

There will be video in the air & very soon!
See you soon so for the rest

Hello Pascal,

new with old

it's a differential drag machine, is not it? Beautiful prototype.

[Pascal HA PHAM]

Hello Pascal,

new with old

it's a differential drag machine, is not it? Beautiful prototype.

Hi Raymundo,
Yes and no: it's new on a patent repechage ...
let me explain
The initial patent of .... pffff .... there is 9 years! had been retorted because of poor organization of claims.
I've started all over again, and taking over, I put my finger on very precious elements that I had not seen at the time.
FINAL: acceptance by the INPI of the initial patent reviewed and corrected and drafting of a second future patent pending.

All this gave me wings to finally build a prototype hight tech while stainless steel and aluminum.

TPGEOP BALANCE TIME
the prototype is finished
with perfect operation:
static and dynamic balancing
The angular positioning of the lateral cam is adjustable on 360 °:
- which allows a perfect adjustment of the wind azimuth during operation
which makes it possible to reverse the direction of rotation during the same exposure to the dynamic vein of the fluid
I'm waiting for the wind for the video ......
another video will be shot in the water of a stream

FEATURES
wingspan 62 cm
width 21 cm
6,5 thickness cm
rotating mass: 8,6 kgp mounted on 2 bearings INOX / central axis INOX

NB: the day before yesterday, 16/02/2017, I received in the mail the patent as it has just been issued to me .... with the new discriminatory claims .... proof that the old patent was " recoverable "

TPGEOP: empty rotations
Note the transition of each grid from the closed position to the open position at the gate crossing point horizontally.
on the first video, the wind comes from the left to the right
on the second video, the wind comes from the top to the bottom
NOTE 1: the grids change state when they are "on the edge", this is the ideal moment when the fluid no longer exerts pressure on their faces.
NOTE 2: this type of turbine can operate in vertical axis, in horizontal axis .... and even in inclined axis = it is the adjustment of the cam on 360 ° which allows the optimal and instantaneous adjustment of the azimuth at wind
It's like for ROBIPLAN:
we start with a laminar flow from the horizontal .... to an angle? (to calculate) .... it is turbulent on both sides of the vertical position for the grid closed .... then one resumes a laminar flow (angle?) before finding the horizontal one, and thus of further on the machine-specific cycle ..... I leave the performance calculations to the fluid specialists. The calculations are probably as complex as on ROBIPLAN.
Unlike ROBIPLAN this concept works in Hydrolienne (deep immersion) and as a surfer points out: the couple looks huge. This concept will therefore be dedicated par excellence to 2 distinct operations: very violent winds like CATABATICS and the deep exploitation of sea currents such as GULF STREAM.
IMPORTANT: the "open" grid is always in laminar flow due to its hydro-dynamic / aerodynamic profiling.

Pascal thank you for this beautiful proto,

we can clearly see the action of the cam with its "2 paths" connected by a small bevelled groove: this allows you to activate your grid alternately open or closed with respect to the flow of the flow.
