Abstract

Timing device for 4-stroke internal combustion engines. The invention relates to the intake and exhaust of these engines. It consists of an exhaust shaft and of an intake shaft, or of a single shaft which can fulfil both these functions, drilled perpendicular to their longitudinal axis and allowing the passage of the gases. These shafts are rotationally driven by the conventional means for driving camshafts.

Description

La présente invention concerne un dispositif de distribution des moteurs à explosion. The present invention relates to a device for distributing internal combustion engines.

L'admission et l'échappetnent de ces moteurs sont tradition nullement effectués par un ou deux arbres à cames,des culbuteurs et des soupapes mettant en jeu la-fragilité de ces pièces,leur usinage assez coûteux et le réglage du jeu necessaire à leur bon fonctionnement. The intake and exhaust of these engines are traditionally not carried out by one or two camshafts, rockers and valves involving the fragility of these parts, their fairly expensive machining and the adjustment of the play necessary for their good operation.

Le dispositif selon l'invention permet de remédier à ces inconvénients. The device according to the invention overcomes these drawbacks.

Conte pour les arbres à caes,on pourra avoir un seul ou deux arbres de distribution (fig 1 et 2).Ces arbres sont perçés perpendiculaire:nent à leur axe longitudinal,ce qui permet le passage des gaz.Ces arbres peuvent être entrainés par chaine, courroie ou une cascade de pignons. Fairy tale for caes, we can have only one or two distribution trees (fig 1 and 2). These trees are drilled perpendicular: lead to their longitudinal axis, which allows the passage of gases. These trees can be driven by chain, belt or cascade of sprockets.

Vu la proximité de la chambre de combustion et donc de la température élevée qui y règne,ces soupapes rotatives devront être réalisées dans un matériau capable de supporter ces tempéra- tures et conservant ses caractéristiques mécaniques à hautes températures.rlles pourront être moulées avec obtention directe des trous de passage des gaz ou être totalement usinées. Given the proximity of the combustion chamber and therefore the high temperature prevailing there, these rotary valves must be made of a material capable of withstanding these temperatures and retaining its mechanical characteristics at high temperatures. They can be molded with direct production gas passage holes or be fully machined.

Selon une variante,le guidage en rotation du dispositif sera réalisé soit dans des paliers lisses entre la culasse S) et le cache culasse (4) représenté fig 2 ,soit par des roulements à billes logés dans la culasse (3) représenté fig 3
Selon une fore de réalisation préférentielle,les trous servant au passage des gaz seront ronds,rectangulaires ou autre et d'une section variant suivant la cylindrée spécifique des cylindres.Alternatively, the device will be guided in rotation either in smooth bearings between the cylinder head S) and the cylinder head cover (4) shown in fig 2, or by ball bearings housed in the cylinder head (3) shown in fig 3
According to a preferred embodiment, the holes used for the passage of gases will be round, rectangular or other and of a section varying according to the specific displacement of the cylinders.

Le diamètre des arbres de distribution sera de l'ordre de 3 à 6 centimètres suivant les trous de passage des gaz,et leur longueur variera suivant le nombre de cylindres à alimenter. The diameter of the distribution shafts will be of the order of 3 to 6 centimeters depending on the gas passage holes, and their length will vary according to the number of cylinders to be supplied.

Selon une forme de réalisation préférentielle,les arbres auront une forme cylindrique continue (fig 4) ou une forme cylindrique échancrée (fig 5). According to a preferred embodiment, the shafts will have a continuous cylindrical shape (fig 4) or a scalloped cylindrical shape (fig 5).

Selon les dimentions de l'arbre et des trous de passage des gaz,on pourra modifier le diagramme de distribution du moteur. Depending on the dimensions of the shaft and the gas passage holes, the engine distribution diagram can be modified.

Selon une fore de réalisation préférentielle,on pourra avoir un seul trou de passage des gaz ou plusieurs par cylindre et par arbre.  According to a preferred embodiment, there may be a single gas passage hole or more per cylinder and per shaft.
