The creation whose patent is hereby requested consists basically of an efficient and simple mechanism for the construction of engines.
In accordance with the Strasbourg Agreement 1971, this invention technologic sector is F 02 B related to Pistons Internal Combustion Engines and Combustion Engines in General.
It is an efficient and simple mechanism for engines construction either with internal combustion or compressed air, steam engines, hydraulic engines of different sizes, for vehicles (cars, motorbikes, launches), that is, in every locomotion field, as stationary drives for generators, water pumps, and wherever motive power is required.
The mechanism used in conventional engines for one century which is piston-bolt-connection rod-crank, has been improved, studied and proved in millions of engines by thousands of technicians in the whole world, constituting the engine we have today with its advantages and defects.
The revolving Wankel engine of German origin also works but it does not surpass the conventional engine since it requires high precision and also exotic materials for its construction which places it on a disadvantageous position with regard to the conventional engine.
In our opinion, conventional engines had two fundamental defects which have not been solved.
1- We start by saying that the length of the lever of the crankshaft bearing can never be longer that 50% of the piston course and taking into account that by means of a connecting road the explosion strength is applied to that lever which is the one that makes the crankshaft rotate, the conventional engine mechanism cannot bear a lever bigger that that and we must remember what Physics has taught us: that the same product can be obtained with a little movement and great strength instead of great movement and little strength. Taking into account the strength which is produced by the explosion generated by the fuel burnt in the combustion chamber, it is clear to understand which of the two fuels will be more convenient to apply in order to make the most of the explosion strength. In the conventional engine mechanism a little course with a great strength is used. As a consequence, the conventional engine mechanism has to work at high revolutions to be able to develop strength. We must not forget that high revolutions generate within the engine inertial strength which tends to vibrate, break and brake the engine rotation which also produces fuel waste and consumption increases. The lever through which the explosion strength is applied to the crankshaft is minimal at the moment of maximum pressure of gases in the combustion chamber and reaches a value of 50% of the piston drive at 90° of the crankshaft rotation and the piston has driven 50% of its drive, therefore, the explosion has lost more that 50% of its strength. With that mechanism it is impossible to increase the piston drive.
2- The conventional engine piston stands strong lateral efforts during its drive in order to transmit the explosion strength to the connecting rod and the latter to the crankshaft lever in order to make it rotate which makes the piston, rings and cylinder suffer undesired frictions and therefore, temperatures, wear and consumption of energies inside the engine which do not come out through the engine axle complicating the sealing of rings and requiring abundant lubrication inside the cylinder. That functioning defect is also impossible to solve in a conventional engine since it works according to its design.
With the rotolinear mechanisms we are dealing with the most important inconveniences of conventional engines get solved in a very advantageous manner as well as other inconveniences it has to suffer in order to work which demand a long technical explanation.
This invention of the transformation of piston alternative movement into an axle revolving movement significantly increases the lever through which the explosion strength is applied to the engine axle and that lowers significantly the engine revolution keeping a high torque at low revolutions per minute (RPM) and therefore, a lower consumption.
Piston lateral efforts are also eliminated and as a consequence, rings are better sealed and a lower temperature in the piston with a minimal lubrication inside the cylinder is obtained.
We understand that at present we need more efficient engines which may (as in this invention) offer users a lower cost, lower fuel consumption, lower manufacturing and maintenance costs and also, a lower environmental contamination.
The above mentioned results are precisely obtained with this new transformations mechanism. This invention has the following advantages:
By using the above mentioned mechanism different varieties of engines can be manufactured which can work with oil derivatives as well as with compressed air engines, steam engines, hydraulic engines and liquids pumps. Due to that, the present invention offers society many advantages in the economic area because they simple engines, cheaper, with lower fuels consumption and lower maintenance costs and they also provoke less environmental damage.
Its design also allows the location of engines factories at places where today it is impossible to manufacture conventional engines or revolving Wankel engines. That means work opportunities for many people and higher quality lives for everyone.
This kind of engine can be used in internal combustion engines, also in compressed air engines, hydraulic engines, steam engines and liquids pumps, therefore, if applied to internal combustion engines, the starting, speed and turning off is similar to a conventional engine.
It is a kit of cams of complementary work in a preferably static position. The main cam has an internal command and with permanent work it is linked to a second cam of similar geometry but with external command in a parallel work position which we shall call “Expansion cam” that works when there is no pressure or strength between the heads of pistons located in a preferably revolving cylinder.
The main cam with internal command showed in
When bearing 4 of
While these two drives take place at the piston we are dealing with, the same happens simultaneously when this piston is facing to the other piston. In this way the mechanism obtains the four drives per piston in the 360° revolving. By setting different degrees substantial improvements are obtained in the compression stage thus decreasing the braking of revolving produced, substantial improvements in bearing 4 surface support point on the sloping surface of cam 1 and improving significantly the bearing 4 movement which moves on the same.
By transforming the alternative piston movement into a revolving movement of central axle 6, the elimination of vibrations to the rotor body is obtained and also more or less revolutions per minute are obtained. Such disposition provides pistons faced under a dynamic perfect balance of masses under alternative movement without counterweights, tugs and smooth movements.
Under N° 7
It is important to express that this mechanism is composed by only 2 pistons.
Cam 2 of expansion and limitation towards the pistons interior works only when follower 5 at the right moment, allowed by the piston drive, lies support on cam 2 imposing radial movement at one moment and limitation towards the opposite pistons interior within cylinder 9, preferably revolving.
In the technique we are dealing with piston-rod-bearing-sloped surface are used. By using them the piston lateral efforts are eliminated and therefore, there is less wear and tear and less temperature, better sealing of rings and lower internal lubrication of the cylinder.
In this mechanism it is possible to extend the lever length through which the explosion strength that makes axle 6 revolve is applied without increasing the piston drive.
The conventional technique uses the piston-bolt-crank. It is not possible to avoid the pistons lateral efforts because it is the support point on the cylinder in order to transmit to the crankshaft the strength that makes it revolve and transform the piston alternative movement into the crankshaft revolving movement carried out by means of the crank that cannot be higher that 50% than the piston drive.
Their main uses are in the industry where motive power is required in different levels of power and also compressed air propellers, steam propellers, hydraulic engines and liquids pumps.
In the book “Explosion Motors” [“Motores a explosión”] by José F. Lucius—1, he explains the transformation of the piston alternative movement into the crankshaft revolving movement by means of the traditional mechanism piston-connecting rod-crank. He also mentions, as a consequence of the above, the piston lateral effort and the other inconveniences that the conventional engine has which have been very well known by technicians for a century.
The present circumstances provoked by the rising prices of oil make us think that we need new propellers to save fuels which contaminate less since the very moment they are created, smaller and lighter, using the same materials. We think there must be a new mechanism which has lower manufacturing and maintenance costs which can be used by the user at a cost lower than the traditional maintenance costs.
