Abstract

The invention relates to a rotary timing device. This device is of the type described in patent FR-86 13525 and characterised in that the timing element 117 comprises resonance means 150 arranged in coincidence with the opening 112 communicating with the treatment chamber 130 when the compression piston 104 is at top dead centre TDC (PMH) just before the expansion. These resonance means 150 may be made up of a resonance cut or cavity 152 whose shape is advantageously substantially parabolic. An improvement in operation is thus obtained, particularly by pushing the shock wave back onto the crown of the compression piston 104.

Description

Dispositif de distribution rotatif à distribution rotative discontinue, pourvu de moyens de résonance.Rotary distribution device with discontinuous rotary distribution, provided with resonance means.

La présente invention concerne essentiellement un dispositif de distribution rotatif à distribution rotative discontinue, pourvu de moyens de résonance. The present invention essentially relates to a rotary distribution device with discontinuous rotary distribution, provided with resonance means.

On a déjà décrit dans le document FR-86-13525 un dispositif de distribution forcée d'un fluide depuis une canalisation dite d'admission à une canalisation dite d'échappement par l'intermédiaire d'une chambre de traitement pouvant comprendre une compression, comprenant un élément distributeur monté rotatif dans un élément de culasse qui comporte au moins trois ouvertures non alignées communiquant entre elles, dont une ouverture d'admission communiquant librement avec la canalisation d'admission, une ouverture intermédiaire communiquant librement avec ladite chambre de traitement et une ouverture d'échappement communiquant librement avec la canalisation d'échappement, ledit élément distributeur comprenant une lumière ne donnant accès à la chambre de traitement, lors de sa rotation, qu'à une seule canalisation à la fois, caractérisé en ce qu'il comprend des moyens de commande en rotation discontinue de l'élément distributeur. Selon un mode de réalisation préféré, les moyens de commande en rotation discontinue de l'élément distributeur comprennent un ensemble mécanique à croix de Malte. Document FR-86-13525 has already described a device for the forced distribution of a fluid from a so-called intake pipe to a so-called exhaust pipe by means of a treatment chamber which may include compression, comprising a distributor element rotatably mounted in a cylinder head element which has at least three non-aligned openings communicating with each other, including an intake opening communicating freely with the intake pipe, an intermediate opening communicating freely with said treatment chamber and a exhaust opening communicating freely with the exhaust pipe, said distributor element comprising a light giving access to the treatment chamber, during its rotation, to only one pipe at a time, characterized in that it comprises control means for discontinuous rotation of the dispensing element. According to a preferred embodiment, the means for controlling discontinuous rotation of the dispensing element comprise a mechanical assembly with a Maltese cross.

Ce dispositif distributeur peut être utilisé soit pour la distribution des moteurs à combustion interne, soit encore pour la distribution de compresseurs à piston, incluant les pompes. This distributor device can be used either for the distribution of internal combustion engines, or for the distribution of piston compressors, including pumps.

Il a été souligné que ce système présente de nombreux avantages techniques, totalement inattendus, notamment aux pages 5 à 7 de ce document. It was pointed out that this system has many technical advantages, completely unexpected, in particular on pages 5 to 7 of this document.

Cependant, on a observé que l'onde de choc produite par l'allumage et la détente des gaz a tendance à pousser les gaz entre la culasse et le roto-distributeur, ce qui peut conduire à des coups de feu d'impact sur le roto-distributeur et à un affaiblissement, voire à une perte de l'étanchéité. However, it has been observed that the shock wave produced by the ignition and expansion of the gases tends to push the gases between the cylinder head and the rotary distributor, which can lead to shots of impact on the roto-distributor and a weakening or even a loss of sealing.

La présente invention a donc pour but de résoudre un nouveau problème technique consistant en la fourniture d'une solution permettant de renvoyer ou repousser l'onde de choc, produite au moment de l'allumage et de la détente des gaz, sur la tête de piston, c'est-à-dire à l'opposé du roto-distributeur, et ce d'une manière très simple, limitant les coûts de fabrication. The present invention therefore aims to solve a new technical problem consisting in the supply of a solution making it possible to return or repel the shock wave, produced at the time of ignition and of the expansion of the gases, on the head of piston, that is to say opposite the roto-distributor, and this in a very simple manner, limiting the manufacturing costs.

Ce nouveau problème technique est résolu pour la première fois de manière satisfaisante par la présente invention. This new technical problem is satisfactorily resolved for the first time by the present invention.

Ainsi, selon la présente invention, on fournit un dispositif de distribution du type décrit dans le document FR-86 13525, caractérisé en ce que l'élément distributeur comprend des moyens de résonance disposés en coincidence avec l'ouverture de communication avec la chambre de traitement lorsque le piston est au point mort haut juste avant la détente. Dans le cas de moteurs, la chambre est le cylindre. Thus, according to the present invention, there is provided a dispensing device of the type described in document FR-86 13525, characterized in that the dispensing element comprises resonance means arranged in coincidence with the opening for communication with the treatment when the piston is in top dead center just before the trigger. In the case of engines, the chamber is the cylinder.

Selon un mode de réalisation préféré, ces moyens de résonance comprennent une saignée ou cavité de résonance, qui est avantageusement disposée dans le sens longitudinal de l'éLément distributeur. According to a preferred embodiment, these resonance means comprise a groove or resonance cavity, which is advantageously arranged in the longitudinal direction of the dispensing element.

Selon encore une autre caractéristique de l'invention, la forme de cette saignée ou de cette cavité de résonance est sensiblement parabolique. According to yet another characteristic of the invention, the shape of this groove or of this resonance cavity is substantially parabolic.

Grâce à cette structure, on aboutit, au moment de l'allumage et de La détente des gaz, à un renvoi sur la tête de piston de l'onde de choc qui se répand normalement sur toutes les parois et qui aurait donc tendance à pousser les gaz entre la culasse et le roto-distributeur. Ainsi, les moyens de résonance selon l'invention permettent de repousser l'onde de choc sur la tête de piston, de diminuer la poussée sur la friction roto-distributeurculasse et d'améliorer ainsi l'étanchéité, et enfin d'éviter les coups de feu d'impact sur le roto-distributeur. Thanks to this structure, one results, at the time of ignition and The relaxation of the gases, in a return on the piston head of the shock wave which normally spreads on all the walls and which would therefore have a tendency to push the gases between the cylinder head and the rotary distributor. Thus, the resonance means according to the invention make it possible to repel the shock wave on the piston head, to reduce the thrust on the rotational distributor friction wheel and thus improve the sealing, and finally to avoid blows impact fire on the rotary distributor.

D'autres buts, caractéristiques et avantages de l'invention apparaitront clairement à la lumière de la description explicative qui va suivre faite en reférence au dessin annexé représentant un mode de réalisation actuellement préféré de l'invention donné simplement à titre d'illustration et qui ne saurait donc en aucune façon limiter la portée de l'invention. Dans les dessins, la figure unique est une vue en coupe,similaire à celle de la figure 2 du document FR-86 13525 précité, d'un dispositif de distribution selon l'invention utilisé pour la distribution d'un moteur à combustion interne, ici à quatre temps, avec le piston situé au point mort haut (PMH). Other objects, characteristics and advantages of the invention will become clear in the light of the explanatory description which follows, given with reference to the appended drawing representing a currently preferred embodiment of the invention given simply by way of illustration and which therefore cannot in any way limit the scope of the invention. In the drawings, the single figure is a sectional view, similar to that of FIG. 2 of the aforementioned document FR-86 13525, of a distribution device according to the invention used for the distribution of an internal combustion engine, here in four stages, with the piston located in top dead center (TDC).

En référence à la figure unique, on peut voir le bloc-cylindres classique d'un moteur, comportant des volumes 102 dans lesquels circule le liquide de refroidissement (type de refroidissement qui peut être éventuellement supprimé avec le genre de moteur qui va être décrit). En 103, on a représenté la chemise intérieure du cylindre, cette chemise pouvant elle-même être en céramique. With reference to the single figure, one can see the conventional cylinder block of an engine, comprising volumes 102 in which the coolant circulates (type of coolant which can be possibly eliminated with the kind of engine which will be described). . In 103, the inner liner of the cylinder is shown, this liner can itself be made of ceramic.

En 104, le piston avec ses segments qui peut éventuellement être recouvert d'une pastille céramique 105 procurant une plus grande efficacité thermique à l'explosion et une meilleure tenue thermique de la tête de piston
Ce bloc-moteur est coiffé par la culasse en céramique formée de deux demi-culasses 106 et 107, la culasse du bas (107) portant, comme cela est clairement visible, par exemple deux bougies 8 et 9 par cylindre. Une seule bougie pourrait grandement suffire, mais la réalisation d'un tel moteur permet de mettre facilement deux bougies, comme décrit dans le document FR-86 13525.In 104, the piston with its segments which can possibly be covered with a ceramic pad 105 providing greater thermal efficiency at explosion and better thermal resistance of the piston head
This engine block is capped by the ceramic cylinder head formed by two half-cylinder heads 106 and 107, the bottom cylinder head (107) carrying, as is clearly visible, for example two spark plugs 8 and 9 per cylinder. A single candle could be enough, but the realization of such an engine allows to easily put two candles, as described in the document FR-86 13525.

En 110, est représenté le joint de culasse et en 111 le joint permettant de réaliser avec une grande précision l'étanchéité entre la culasse et l'élément distributeur rotatif ou roto-distribu- teur repéré par le numéro de référence général 117. La demi-culasse inférieure comporte une ouverture centrale 112 débouchant sur un demi-palier en 113, la demi-culasse du haut (106) comporte également un demi-palier en 114, chacun de ces demi-paliers débouchant euxmêmes sur deux sorties latérales 115 et 116 communiquant avec des conduits d'admission A et d'échappement E. La section des sorties latérales 115 et 116 peut être sensiblement identique tout en étant légèrement inférieure à celle de l'ouverture centrale 112 pour faciliter l'écoulement des gaz selon la position de l'arbre rotodistributeur 117 servant de vanne ouvrant successivement les orifices 115 et 116. In 110, the cylinder head gasket is shown and in 111 the gasket making it possible to achieve with great precision the seal between the cylinder head and the rotary or rotational distributor element identified by the general reference number 117. The half -lower cylinder head has a central opening 112 opening onto a half-bearing at 113, the upper half-cylinder head (106) also comprises a half-bearing at 114, each of these half-bearings opening themselves onto two lateral outlets 115 and 116 communicating with intake and exhaust ducts E. The section of the lateral outlets 115 and 116 can be substantially identical while being slightly smaller than that of the central opening 112 to facilitate the flow of gases according to the position of the rotary distributor shaft 117 serving as a valve successively opening the orifices 115 and 116.

Cet arbre roto-distributeur 117 comprend une lumière 118 ne donnant accès à la chambre de combustion 130,lors de sa rotation,qu'à une seule canalisation à la fois, soit l'admission, soit l'échappement. La forme de cette lumière 118 peut être en demi-lune.  This rotary distributor shaft 117 includes a light 118 giving access to the combustion chamber 130, during its rotation, to only one pipe at a time, either the intake or the exhaust. The shape of this light 118 may be in the shape of a half moon.

Selon la présente invention, l'élément distributeur 117 ou roto-distributeur est caractérisé en ce qu'il comprend des moyens de résonance 150 disposés en coincidence avec l'ouverture 112 de communication avec la chambre de traitement 130 lorsque le piston de compression est au point mort haut (PMH) juste avant la détente, c'est-à-dire dans la position représentée à la figure unique. De préference, ces moyens de résonance 150 comprennent une saignée 152 ou cavité de résonance. Avantageusement, la forme de cette saignée 152 ou cavité de résonance est sensiblement parabolique, comme représenté dans la figure unique, cette forme faisant partie intégrante de l'invention. According to the present invention, the distributor element 117 or roto-distributor is characterized in that it comprises resonance means 150 arranged in coincidence with the opening 112 of communication with the treatment chamber 130 when the compression piston is at top dead center (TDC) just before the trigger, that is to say in the position shown in the single figure. Preferably, these resonance means 150 comprise a groove 152 or resonance cavity. Advantageously, the shape of this groove 152 or resonance cavity is substantially parabolic, as shown in the single figure, this shape being an integral part of the invention.

Avantageusement, l'élément roto-distributeur 117 est animé d'un mouvement de rotation discontinu conformément à ce qui est décrit dans le document FR-86 13525, notamment par un système à croix de Malte. On a en effet pu observer que les moyens de résonance selon l'invention 150 produisaient un effet de synergie particulièrement inattendu dans le cadre d'une rotation discontinue de l'élément roto-distributeur 117, alors que l'avantage apporté par la présence de ces moyens de résonance 150 était plus limité dans le cadre d'une rotation continue de l'élément roto-distributeur 117. Advantageously, the rotary distributor element 117 is driven in a discontinuous rotational movement in accordance with what is described in document FR-86 13525, in particular by a Maltese cross system. It has in fact been observed that the resonance means according to the invention 150 produced a particularly unexpected synergistic effect in the context of a discontinuous rotation of the rotary distributor element 117, while the advantage provided by the presence of these resonance means 150 were more limited in the context of a continuous rotation of the roto-distributor element 117.

Le fonctionnement est strictement identique à ce qui a été décrit dans le document FR-86 13525 avec l'obtention des avantages précédemment mentionnés inhérents à la présence des moyens de résonance 150, à savoir le fait de renvoyer sur la tête de piston 104, notamment sur la pastille céramique 105, hautement réfractaire, les gaz chauds accompagnés de l'onde de choc, en diminuant ainsi la poussée sur la friction roto-distributeur 117-culasse, en améliorant ainsi l'étanchéité, et en évitant les coups de feu d'impact sur le roto-distributeur 117. The operation is strictly identical to what has been described in the document FR-86 13525 with the obtaining of the previously mentioned advantages inherent in the presence of the resonance means 150, namely the fact of returning to the piston head 104, in particular on the highly refractory ceramic tablet 105, the hot gases accompanied by the shock wave, thereby reducing the thrust on the roto-distributor friction 117-cylinder head, thereby improving the seal, and avoiding the shots of impact on the rotary distributor 117.

On comprend ainsi que l'invention permet d'apporter des perfectionnements techniques déterminants, tout à fait inattendus et non évidents pour l'homme de l'art. It is thus understood that the invention makes it possible to provide decisive technical improvements, completely unexpected and not obvious to those skilled in the art.

Naturellement, l'invention comprend tous les moyens constituant des équivalents techniques des moyens décrits ainsi que
Leurs diverses combinaisons. Naturally, the invention includes all the means constituting technical equivalents of the means described as well as
Their various combinations.
