MPRBC 's Final Design step 43 / 50
The previous image showed a central ball thrust bearing, the latter has a second eccentric ball thrust bearing.
Therefore, the rotary shutter turned between 2 thrust ball bearings according to the technical recommendations of the SAERE
After a break-in period, this makes it possible to remove the friction almost completely and to have perfectly fitted parts.
Machine controlled beating in rotary piston (MPRBC)
MPRBC 's Final Design step 44 / 50
As for the SAERE,
the rotary shutter uses a bearing-mounted pivot to ensure guidance with little friction.
In addition, lights placed on the lower radius for admissions and large radius openings for fluid escapements will be used on the machine.

maximum rotation speed?
Hello Raymond,
finally, thanks to the assembly of all the elements on bearings and in order to perfectly balance all the rotating / dynamic elements, the maximum speed of rotation can be very high!
what order in a successful configuration?
The unavoidable inertia being the back and forth pallets and beat control organs: probably then it is necessary to use light metal parts = for example aluminum alloy for pallets and titanium for the elements of beat control?

Well done Pascal,
Up to the RPMs of the 1 Formulas (10 000 rpm) can be mounted because the MPRBC is balanced, especially with the perfect synchronization of the 4 pistons by the gears.
With the "Final Design", everyone can realize that the design of the MPRBC is now very successful. There has been a long way since 2003 ...
These gears can be external (on the rockers) or inner on the width of the rotary pistons.
However my priority is not to go immediately on high tech, but on robust, efficient and cheap ...
However, this does not close the door to very high energy density motors for competition or aviation ...

MPRBC 's Final Design step 45 / 50
The closing plate is put in place on the gas exchange side. It also supports 2 pivots: that of the rotary valve and that of the auxiliary transmission shaft.
We observe 8 openings including 4 on a small radius and 4 on a large radius.
This allows for example to breathe air on the lights placed on the outer rays (intake) and to drive air through the lights located on the internal radii (exhaust).

Remundo wrote:The main objective of this engine is to have maximum compactness. It should be noted that the volume of fresh gas sucked by this engine is proportional to the square of its characteristic dimension, which can be defined by twice the length of the rotary pistons, unlike traditional engines piston / rod / crank which aspire only volumes proportional to their characteristic dimension, which can be defined by the stroke of the piston.
In addition, all engine accessories, except injectors, have a reduced volume to a minimum. This gives the motor object of the invention an exceptional compactness.
At equal power, the compactness could be increased by an 3 factor compared to a piston / crank / crank / casing motor, and even by an 4 factor by removing the E1 stage, and even more by using a cam rotating central super-lobed.
As an extension of this high compactness, the volumes and masses of material required for the construction of such an engine would be much lower than those required by current techniques. Dimensioned for 100 Bar pressures, the machine object of the invention would use between 20 and 25 kg of steel of standard quality in the material per liter of displacement.
Hi Remundo! you are a Geniuser!
hat down, great as engine!
My question is: what would be the optimal size of an engine of this type? (You talk about 20 to 25 kg of steel).
Could it be miniaturized?
I would see him climb on an ultralight or para-motor !?
In any case my respects is a hell of a job! all my wishes
of success for development!

Hi Sen No Sen,
Thank you for your compliments. I do not know if I am a genius, but in any case I use to the maximum my small intellectual means.
There is no "optimal" size. Simply, the lower the machining precision, the more we can go on small parts.
To give you an idea of the weight of a small engine, you need 20 kg / Liter of capacity that gives about 60 Ch.
20 kg for 60 ch, it's 1 kg for 3 horses ... 3 kg for 10 Ch ...

Of course Sen No Sen, you have noted the essential.
For our site, I must admit that the visual aspect is a little artisanal, but I strive to make the background and functionality prevail over the shape.
As you have seen, there is this page which summarizes the possible applications of the MPRBC in relation to their parameterization / objective.
