Description
Titre de l'invention La présente invention concerne des dispositifs qui permettent la suppression de la courroie de distribution ainsi que la commande de l'arbre à cames qui actionnent les soupapes sur les moteurs thermiques quatre temps. Par l'intermédiaire d'un embiellage les courroies de distribution entraînent les culbuteurs et les soupapes d'un moteur traditionnel. Cet entraînement nécessite un effort du moteur qui se traduit par une perte de performance. En supprimant cet effort, l' invention permet d'augmenter les performances des moteurs, mais aussi de réduire la consommation en diminuant la cylindrée à performance égale Le graissage du haut de cylindre, (c'est à dire toute la culbuterie) étant supprimé, l'huile sera moins chauffée, ce qui se traduira par un vieillissement beaucoup moins important de celle-ci et la suppression de la pompe à huile La péremption de ces courroies est tributaire d'un vieillissement et d'un nombre de kilomètres parcourus. L'invention supprime cette maintenance assez onéreuse et permet une interchangeabilité rapide de ce système. Pour toutes ces raisons l'invention propose : Premièrement deux électrovannes (figl/5) montées en têtes bêches qui actionnent le même entrefer (6) (fig. 1). Les deux bobinages (5) et (7) sont séparés par une cale isolante (10). La queue de soupape (1) comprend un épaulement (11), il permet de bloquer l'entrefer (6) avec la vis (8). Un ressort (4) permet de maintenir juste la soupape en position fermée quand le contact est coupé, il est guidé et maintenu dans la cale isolante (3). Au montage la soupape (1) est positionnée dans la culasse (2), la cale (3) et le ressort (4) puis l'entrefer (6) et l'ensemble est bloqué avec l'écrou conique (8) puis la bobine (5), la cale isolante (10), la bobine (7) et le capot (9) coiffe l'ensemble, les vis (12) maintiennent le capot (9) sur la culasse (2). Ce système permettra un montage et une maintenance aisée (voir fonctionnement fig 3/5), un distributeur électronique et un inverseur géreront en même temps que l'allumage ces électrovannes. Deuxièmement deux électrovannes (fig2/5) montées en tête-bêche qui actionnent deux entrefer (6) et (14) séparés par une cale isolante (13) (fig.1) et (fig2). Les deux bobinages (5) et (7) sont séparés par une cale isolante (10), la queue de soupape (1) comprend un épaulement (11). Il permet de bloquer l'entrefer (6) la cale (13), l'entrefer (14) avec la vis conique (8). Un ressort (4) permet de maintenir la soupape juste en position fermée quand le contact est coupé, il est guidé et maintenu dans la cale isolante (3). Au montage la soupape (1) est positionnée dans la culasse (2) et reçoit la cale (3). Le ressort (4) l'entre -fer (14) la cale isolante (13) l'entrefer (6) et l'ensemble (soupape et entrefer) est bloqué avec l'écrou conique (8) la bobine (5) la cale (10) la bobine (7) et le capot (9) coiffe l'ensemble. Les vis (12) maintiennent le capot (9) sur la culasse (2). Le ressort (4) permet de maintenir la soupape juste en position fermée quand le contact est coupé, il est guidé et maintenu dans la cale (3) En maintenance il suffit de dévisser le capot (9) avec les vis (12) et l'ensemble capot électroaimants ainsi que la cale (10) seront remplacés sans démontage des soupapes. Troisièmement les queues de soupapes ont un angle de sortie de la culasse qui ne nous permet pas de créer un ensemble compact d'électroaimants en maintenance, mais par contre il sera possible de créer deux ensembles (fig3/5) qui seront placés en (v) de chaque côtés de la culasse, ces ensembles seront équipés d'ailettes de refroidissement (15) et seul le changement des bobines en cas de réparation sera nécessaire. L'invention prévoie afin de maintenir fermées les queues de soupapes pendant le changement des bobines, un piquage qui sera prévu sur la culasse pour envoyer de la pression et maintenir les queues de soupapes en position levées Quatrièmement la céramique ayant un pouvoir diélectrique c'est à dire q' elle se dilate sous excitation électrique, elle sera utilisée dans ce cas là à la place des électrovannes pour activer les soupapes (fig4/5). La dilatation, donc le débattement de la céramique est obtenue en fonction de son épaisseur et la force nécessaire à l'ouverture de la soupape est obtenue suivant l'importance de son diamètre La (figl) représente la soupape (2) en position fermée, la culasse (1) dans laquelle est incérée la soupape (2), le ressort (3), le flasque (6) dans lequel est attelé la queue de soupape (2), la céramique (4) non excitée, le capot (5) et les vis (7) de fixation du capot (5) La (fig2) représente la soupape (2) en position ouverte sur le siège de la culasse (1) le ressort (3) est comprimé et repoussé par la céramique (4) qui est excitée et le flasque (6) qui est attelé à la queue de soupape (2) La (fig5/5) représente l'utilisation de la céramique sans le ressort de rappel, c'est une deuxième céramique qui servira de ressort, elle sera utilisée comme pour les électrovannes (fig1/5) La (fig 1) représente la soupape (2) en position fermée sur le siège de la culasse (1) la céramique (3) qui est existée, est dilatée ; elle est séparée de la culasse par une cale isolante (8), un flasque (6) sépare la deuxième céramique (4) ,la queue de soupape traverse les deux céramiques ainsi que le flasque (6) et est attelée à la céramique (4) avec la vis conique (9) , le capot (5) est fixé sur la culasse avec la vis (7) Fonctionnement double électroaimants montés en tête-bêche soupape ouverte et fermée avec le même entrefer (figl/5) Fonctionnement soupape ouverte (fig1) L'ouverture de la soupape (1) se fera par l'excitation de la bobine (7) qui actionnera l'entrefer (6) pendant que la bobine (5) sera au repos Fonctionnement soupape fermée (fig2) La fermeture de la soupape (1) se fera par l'excitation de la bobine (5) qui actionnera l'entrefer (6) pendant que la bobine (7) sera au repos. L'entrefer (6) sera commun et le ressort (4) maintiendra une force suffisante juste pour repousser l'entrefer (6) et fermer la soupape quand les deux bobines sont au repos. Fonctionnement double électroaimants montés en tête-bêche avec deux entrefers séparés (fig2/5). Fonctionnement soupape ouverte (figl) La bobine (7) est excitée son entrefer (6) comprime le ressort (4) et ouvre la soupape (1) la bobine (5) est au repos et son entrefer (14) suit le mouvement. Fonctionnement soupape fermée (fig2) La bobine (5) est excitée son entrefer (14) repousse et ferme la soupape (1) la bobine (7) est au repos et son entrefer (6) suit le mouvement Fonctionnement (fig3/5) pour le changement des ensembles des bobines en maintenance la (figl) représente l'entrefer en deux parties, la (fig2) représente l'entrefer en une seule partie. La soupape étant positionnée en (v) le haut de la culasse (2) aura un angle de sortie de façon à permettre de bien positionner les ensembles bobines dans l'axe. En maintenance on dévisse de chaque côté ces ensembles constitués de deux blocs compacts équipés de ses ailettes de refroidissement (15) exemple (fig 2), avec les vis (12) et on retire les capots (9) les bobines (5) et (7) la cale (10), l'ensemble soupape entrefer restera dans la culasse. Deux nouveaux ensembles pré-cablés remplaceront en maintenance les anciens équipements Fonctionnement (fig 4/5) avec une céramique et ressort de rappel.FIELD OF THE INVENTION The present invention relates to devices which allow the removal of the timing belt as well as the control of the camshaft which actuates the valves on the four-stroke thermal engines. Through a linkage the timing belts drive the rocker arms and valves of a traditional engine. This training requires a motor effort that results in a loss of performance. By eliminating this effort, the invention makes it possible to increase the performances of the engines, but also to reduce the consumption by decreasing the cubic capacity with equal performance The lubrication of the top of the cylinder, (ie all the tumbler) being eliminated, the oil will be less heated, which will result in much less aging of the oil and the removal of the oil pump The expiry of these belts is dependent on aging and a number of kilometers traveled. The invention removes this rather expensive maintenance and allows rapid interchangeability of this system. For all these reasons the invention proposes: First two solenoid valves (figl / 5) mounted on spade heads which actuate the same gap (6) (FIG 1). The two coils (5) and (7) are separated by an insulating shim (10). The valve stem (1) comprises a shoulder (11), it blocks the gap (6) with the screw (8). A spring (4) keeps the valve just in the closed position when the contact is cut, it is guided and maintained in the insulating shim (3). On mounting the valve (1) is positioned in the cylinder head (2), the shim (3) and the spring (4) and the gap (6) and the assembly is blocked with the conical nut (8) and the coil (5), the insulating shim (10), the coil (7) and the cover (9) cap the assembly, the screws (12) hold the cover (9) on the yoke (2). This system will allow easy assembly and maintenance (see operation fig 3/5), an electronic distributor and an inverter will manage at the same time as the ignition these solenoid valves. Second two solenoid valves (fig2 / 5) mounted in the head to tail which actuate two air gap (6) and (14) separated by an insulating shim (13) (fig.1) and (fig2). The two coils (5) and (7) are separated by an insulating shim (10), the valve stem (1) comprises a shoulder (11). It blocks the gap (6) the shim (13), the gap (14) with the conical screw (8). A spring (4) keeps the valve just closed when the contact is cut, it is guided and held in the insulating shim (3). On mounting the valve (1) is positioned in the cylinder head (2) and receives the shim (3). The spring (4) the air gap (14) the insulating shim (13) the gap (6) and the assembly (valve and gap) is blocked with the conical nut (8) the coil (5) the wedge (10) the coil (7) and the cover (9) covers the assembly. The screws (12) hold the cover (9) on the cylinder head (2). The spring (4) keeps the valve just closed when the ignition is off, it is guided and held in the hold (3) In maintenance simply unscrew the cover (9) with the screws (12) and the The electromagnet bonnet assembly and the shim (10) will be replaced without disassembly of the valves. Third, the valve stems have an angle of exit of the cylinder head that does not allow us to create a compact set of electromagnets in maintenance, but against it will be possible to create two sets (fig3 / 5) which will be placed in (v ) on each side of the cylinder head, these assemblies shall be equipped with cooling fins (15) and only the change of the coils in case of repair will be necessary. The invention provides for keeping the valve stems closed during the change of the coils, a stitching which will be provided on the cylinder head to send pressure and maintain the valve stems in the raised position Fourthly the ceramic having a dielectric power is to say that it expands under electrical excitation, it will be used in this case instead of solenoid valves to activate the valves (fig4 / 5). The expansion, therefore the travel of the ceramic is obtained according to its thickness and the force required for the opening of the valve is obtained according to the importance of its diameter La (figl) represents the valve (2) in the closed position, the cylinder head (1) in which the valve (2), the spring (3), the flange (6) into which the valve stem (2) is coupled, the non-excited ceramic (4), the hood (5) are inserted. ) and the screws (7) for fixing the cover (5) The (fig2) represents the valve (2) in the open position on the seat of the cylinder head (1) the spring (3) is compressed and pushed back by the ceramic (4) ) which is excited and the flange (6) which is coupled to the valve stem (2) La (fig5 / 5) represents the use of the ceramic without the return spring, it is a second ceramic which will serve as a spring , it will be used as for the solenoid valves (fig1 / 5) The (fig 1) represents the valve (2) in the closed position on the seat of the cylinder head (1) the ceramic (3) which is existed, is dilated; it is separated from the cylinder head by an insulating wedge (8), a flange (6) separates the second ceramic (4), the valve stem passes through the two ceramics as well as the flange (6) and is coupled to the ceramic (4 ) with the conical screw (9), the cover (5) is fixed on the cylinder head with the screw (7) Operation double electromagnets mounted head-to-tail valve open and closed with the same air gap (figl / 5) Open valve operation ( fig1) The opening of the valve (1) will be done by the excitation of the coil (7) which will activate the gap (6) while the coil (5) is at rest Closed valve operation (fig2) The closing of the valve (1) will be by the excitation of the coil (5) which will actuate the gap (6) while the coil (7) is at rest. The air gap (6) will be common and the spring (4) will maintain sufficient force just to push the air gap (6) and close the valve when the two coils are at rest. Dual electromagnet operation mounted head-to-tail with two separate air gaps (fig2 / 5). Open valve operation (figl) The coil (7) is energized its gap (6) compresses the spring (4) and opens the valve (1) the coil (5) is at rest and its air gap (14) follows the movement. Closed valve operation (fig2) The coil (5) is energized its air gap (14) pushes and closes the valve (1) the coil (7) is at rest and its air gap (6) follows the movement Operation (fig3 / 5) for the change of assemblies of the coils in maintenance (figl) represents the air gap in two parts, the (fig2) represents the gap in one part. The valve being positioned in (v) the top of the cylinder head (2) will have an exit angle so as to properly position the coil assemblies in the axis. In maintenance, these assemblies consisting of two compact blocks equipped with its cooling fins (15) example (FIG. 2), with the screws (12) are removed from each side and the covers (9) are removed from the coils (5) and (FIG. 7) the shim (10), the gap valve assembly will remain in the cylinder head. Two new pre-wired assemblies will replace in maintenance the old equipment Operation (fig 4/5) with a ceramic and return spring.
