Abstract

Device allowing filling and emptying of the cylinders of a mechanical internal combustion engine. The invention relates to a mechanical part of the cylinder head 3 equipped with openings 2 which allow the passage of gases for filling 7 and emptying 8 of four-stroke internal combustion cylinders. It relates to a shaft 1 which, rotating on itself, allows the passage of fresh gases during the stroke favourable for admission 7, and burnt gases during the exhaust stroke 8. The device is intended for all internal combustion engines necessitating a fuel feed for their operation.

Description

La présente invention concerne une pièce mécanique relative pour permettre l'admission et ltéchappement des gaz d'un moteur à explosions à quatre temps. The present invention relates to a relative mechanical part for allowing the intake and exhaust of gases from a four-stroke explosion engine.

L'admission et l'échappement des gaz d'un moteur à explosions se faisant traditionnellement par des soùpapes ce qui occasionne un mauvais remplissage et vidage des cylindres ainsi que l'entrainement néfaste d'une inertie inutile à un régime peu elevé de rotation de ces moteurs. The admission and exhaust of gases from an explosion engine traditionally done by valves which causes poor filling and emptying of the cylinders as well as the harmful drive of unnecessary inertia at a low speed of rotation of these engines.

Le dispositif, selon l'invention, permet de remédier à ces incon venients.Il se compose en effet d'un arbre (I) percé d'ouvertures (2) par lesquelles s'introduisent les gaz d'admission (7) et stéchappent les gaz brûlés (8) au moment propice du temps moteur, comme un moteur classique a quatre temps1 mais n'ayant pas une culasse pourvue de soupapes, mais d'un arbre percé d'ouvertures (2) qui pressente son orifice au même moment oli dans le cas d'un moteur classique une soupape s'ouvrirait.Cet arbre (I) est entraine directement par le vilbrequin (6-)à l'aide d'une courroie (IO), d'une chaîne (IO) ou d'un arbre (IO) de transmission.I1 est repré sent sur la figure 9 du plan 2. The device according to the invention makes it possible to remedy these drawbacks. It consists in fact of a shaft (I) pierced with openings (2) through which the intake gases (7) are introduced and escape the burnt gases (8) at the auspicious time of the engine time, like a conventional four-stroke engine1 but not having a cylinder head provided with valves, but with a shaft pierced with openings (2) which senses its orifice at the same time oli in the case of a conventional engine a valve would open.This shaft (I) is driven directly by the crankshaft (6-) using a belt (IO), a chain (IO) or of a transmission shaft (IO). I1 is represented in FIG. 9 of plane 2.

On peut ainsi voir sur le figure I du plan I le piston (4) en haut du cylindre (5) qui vient de remonter en repoussant les gaz brûlés vers le conduit d'échappement (8) alors que litarifice de l'arbre s'est présen te; favorablement pour ltécoulement de ces gaz.Il est à noter, que lorsque le vilbrequin (6) -e'ffectue un demi tour pour remonter le piston ou l'abaisser, c'est a dire que le vilbrequin (6) éffectue un mouvement de 1800, l'arbre (I) d'ouverture (2), lui, ne tourne que de 450, ce qui lui permet, gracie à ce temps plus long, de bien remplir ou de vider les cylindres (5) de leurs gaz. We can thus see in Figure I of plan I the piston (4) at the top of the cylinder (5) which has just risen by pushing the burnt gases towards the exhaust duct (8) while the shaft opening is is present; favorably for the flow of these gases. It should be noted that when the crankshaft (6) - makes a half turn to raise or lower the piston, that is to say that the crankshaft (6) makes a movement of 1800, the opening shaft (I) (2), for its part, only turns 450, which allows it, thanks to this longer time, to fill or empty the cylinders (5) with their gases.

Sur le figure 2 du plan I, l'on peut constater que le piston (4) est à nouveau redescendu au fond du cylindre (5) en aspirant les gaz frais d'admission que ltorifice (2) de l'arbre (I) d'ouverture (2), maintenant tourné de nouveau de 450 vers la pipe d'admission (7), a permit le passage, ce qui est le premier temps d'un moteur à explosions. In FIG. 2 of plane I, it can be seen that the piston (4) has again descended to the bottom of the cylinder (5) by sucking in the fresh intake gases that the orifice (2) of the shaft (I) opening (2), now turned again 450 towards the intake pipe (7), allowed the passage, which is the first time of an explosion engine.

Sur la figure 3 du plan I, le piston (4) en remontant comprime les gaz admis précéde,ent pour arriver en haut et ce sera l'explosion, donc, le deuxième temps. In Figure 3 of plane I, the piston (4) going up compresses the gas admitted before, ent to get to the top and it will be the explosion, therefore, the second time.

Te piston (4) redescend, sur le figure 4 du plan I, ce qui est la détente est donc le troisième temps moteur.  Te piston (4) descends, in Figure 4 of plane I, which is the trigger is the third engine time.

Entre la figure 4 du plan I et la figure I du plan I, le piston (4) va remonter et repousser les gaz brûlés vers l'orifice d'ouverture (2) de l'arbre (I) qui viendra se présenter sur le conduit d'échappement (8).Ce sera donc le quatrième temps et le dernier du cycle d'un moteur à explosions à quatre temps. Between FIG. 4 of plane I and FIG. I of plane I, the piston (4) will go up and push back the burnt gases towards the opening orifice (2) of the shaft (I) which will come to appear on the exhaust pipe (8). This will be the fourth and last stroke in the cycle of a four-stroke explosion engine.

Sur les figures 5, 6, 7, 8 du plan I, on peut voir le même systè- me que précédement mais avec un nouveau dessin des orifices d'ouverture (2), ce qui permet d'avoir un temps de remplissage et de vidage moins important du fait que cet arbre (I) tourne de 100 à chaque temps moteur alors que le vilbrequin qui, je le rappelle, entraine l'arbre (I)dtouver- ture (2), tournerait lui, toujours de I800 par temps moteur. In Figures 5, 6, 7, 8 of plane I, we can see the same system as before but with a new design of the opening holes (2), which allows to have a filling time and emptying less important because this shaft (I) rotates by 100 at each engine time while the crankshaft which, I remind you, drives the shaft (I) to find (2), would turn it, always by I800 per time engine.

Sur la figure 9 du plan 2, on peut voir la coupe d'un moteur à explosions composé de quatre cylindres (5).L'arbre est entraîné directement par une courroie (IO) crantée, à l'aide d'une poulie (9) en bout de l'arbre d'ouverture et d'une poulie (9) en bout de vilbrequin (6).L'arbre (I) d'ouverture (2) ne tourne que de I800 pour éffectuer les quatre temps moteur soit: l'admission (7), compression, explosion détente, échappement (8), alors que le vilbrequin a lui-même effectué deux tours de rotation ce qui représente quatre tours de vilbrequin (6) pour un tour d'arbre (I) d'ouverture (2). In Figure 9 of plane 2, we can see the section of an explosion engine composed of four cylinders (5) .The shaft is driven directly by a toothed belt (IO), using a pulley ( 9) at the end of the opening shaft and a pulley (9) at the end of the crankshaft (6) .The opening shaft (I) (2) only rotates I800 to perform the four-stroke engine either: the intake (7), compression, detent explosion, exhaust (8), while the crankshaft has itself made two rotational turns which represents four crankshaft turns (6) for one shaft turn (I ) opening (2).

Ce temps très long d'ouverture, par rapport à la distance éffectu par le piston (4) dans le cylindre, permet un très bon remplissage et vi- dage des gaz dans les cylindres (5).le débit des gaz peut d'ailleurs êtr réglé par le calibrage des orifices d'ouverture (2) de l'arbre (I).De plus la faible vitesse de rotation de l'arbre (I) d'ouverture (2) permet d'ail menter la vitesse de rotation d'un moteur classique sans que celui-ci n connaisse l'affollement en distribution, bien connu des moteurs culbutés classiques.  This very long opening time, compared to the distance effected by the piston (4) in the cylinder, allows a very good filling and emptying of the gases in the cylinders (5). be adjusted by calibrating the opening holes (2) of the shaft (I). In addition the low speed of rotation of the shaft (I) of opening (2) also allows the speed of rotation to be increased of a conventional engine without the latter experiencing the breakdown in distribution, well known to conventional overturned engines.
