Description

DISPOSITIF REGULATEURREGULATOR DEVICE

DESTINE AUX PETITS MOTEURS THERMIQUES  INTENDED FOR SMALL THERMAL ENGINES

La présente invention se rapporte au domaine de la mécani-5 que et plus particulièrement aux engins de motorisation.  The present invention relates to the field of mechanics and more particularly to motorization machines.

Elle a plus particulièrement pour objet un dispositif régulateur destiné aux petits moteurs thermiques à 2 ou 4 temps.  It relates more particularly to a regulator device for small thermal engines 2 or 4 times.

Elle a spécifiquement pour objet un dispositif de régulation destiné à l'ensemble des petits moteurs thermiques, utilisés principalement sur des matériels de jardinage, tels que tondeuses à gazon, motoculteurs, pompes à eau, groupes électrogènes, etc...  It specifically relates to a control device for all small heat engines, used mainly on gardening equipment, such as lawn mowers, tillers, water pumps, generators, etc ...

L'invention a donc pour objet un dispositif de régulation du régime du moteur qui consiste en ce que l'on modifie la tension du ressort de régulation au moyen d'une patte de tension que l'on plie vers l'intérieur ou vers l'extérieur, sous l'influence d'un moyen de basculement monté rotatif autour d'un axe de rotation et entraînant le ressort de tension autour d'une position médiane entre une position de tension et une position de détente du ressort.  The subject of the invention is therefore a device for regulating the speed of the engine, which consists of modifying the tension of the regulation spring by means of a tension tab which is folded inwards or towards the inside. outside, under the influence of a tilting means rotatably mounted about an axis of rotation and driving the tension spring about a median position between a tension position and a spring expansion position.

Le système de régulation selon l'invention comporte, en outre, un dispositif de protection du type carter, constitué par une plaque empêchant la collision de tous les points du système de régulation par des objets étrangers, pour cacher le système aux yeux de l'utilisateur, afin que celui-ce ne soit pas tenté d'en modifier le réglage, et ainsi de le dérégler, et de rendre ainsi très difficile toute opération de modification du réglage du régime mo- teur sans disposer d'un outillage approprié.  The control system according to the invention further comprises a protection device of the housing type, consisting of a plate preventing the collision of all the points of the control system by foreign objects, to hide the system in the eyes of the the user, so that it is not tempted to modify the setting, and thus to disrupt it, and thus make it very difficult any operation to change the engine speed adjustment without having appropriate tools.

La patte de tension se présente sous la forme d'une plaque métallique rigide, terminée par un bras déformable où vient se fixer le ressort de tension. Le ressort de tension est assujetti à l'autre extrémité au levier de basculement commandé par l'axe régulateur sortant du cylindre moteur.  The tension tab is in the form of a rigid metal plate, terminated by a deformable arm where is fixed the tension spring. The tension spring is secured at the other end to the tilting lever controlled by the regulating pin exiting the engine cylinder.

A la différence de la très grande majorité des systèmes de régulation mécaniques centrifuges, dans lesquels le réglage du régime du moteur est obtenu par modification de la tension du ressort de régulation, et qui peut se dérégler, le présent dispositif assure l'augmentation ou la diminution de la tension du ressort de régulation et, par voie de conséquence, le régime du moteur par pliage d'une patte qui agit sur la tension du ressort de régulation.  Unlike the vast majority of centrifugal mechanical control systems, in which the adjustment of the engine speed is obtained by changing the tension of the control spring, and which may be out of adjustment, the present device ensures the increase or decrease of decreasing the tension of the control spring and, consequently, the speed of the motor by folding a tab which acts on the tension of the control spring.

Le dispositif selon l'invention a donc pour but de simplifier la commande d'accélérateur ainsi que le réglage du régime maximum du moteur, de réduire de manière importante les coûts de fabrication, d'améliorer la précision du réglage du régime moteur pour un meilleur respect de la norme bruit du matériel de jardinage sur lequel ledit moteur est appliqué et, en même temps, d'améliorer la protection de l'ensemble de façon à empêcher, voire même interdire, à l'utilisateur non averti d'apporter toute modification éventuelle aussi bien provoquée par une cause accidentelle que résultant d'une manière volontaire de l'intervention de l'utilisateur.  The device according to the invention therefore aims to simplify the throttle control and the adjustment of the maximum speed of the engine, significantly reduce manufacturing costs, improve the accuracy of the engine speed adjustment for better respecting the noise standard of the gardening equipment on which the motor is applied and, at the same time, improving the protection of the assembly so as to prevent or even prohibit the unsuspecting user from making any modifications possibly caused by an accidental cause as a result of a voluntary intervention of the user.

Le dispositif selon l'invention est destinée à être utilisé sur des petits moteurs thermiques culbutés (OHV) ou à arbre à cames en tête (OHC). On réalise ainsi une application particulière, à savoir le maintient d'un régime fixe sur moteur OHV et sur moteur OHC.  The device according to the invention is intended to be used on small thermal engines tumbled (OHV) or overhead camshaft (OHC). A particular application is thus carried out, namely the maintenance of a fixed speed on an OHV motor and on an OHC motor.

La figure unique montre en plan le dispositif de régulation se- lon l'invention. Il comporte les pièces suivantes, vue par au-dessus. On voit, en A, la plaque de fixation du levier de régulation, en (C) le levier de régulation, en (D), le ressort de régulation et en (E) l'axe de régulation monté rotatif permettant le basculement du levier de régulation (C). Le ressort (D) est fixé à l'extrémité de la plaque (C) De cette façon, tout déplacement du levier (C) autour de l'axe (E) se transmet au ressort (D).  The single figure shows in plan the regulating device according to the invention. It comprises the following parts, seen from above. We can see, at A, the fixing plate of the regulation lever, in (C) the regulating lever, in (D), the regulation spring and in (E) the rotatably mounted regulating axis allowing the lever to tilt. regulation (C). The spring (D) is fixed to the end of the plate (C). In this way, any movement of the lever (C) around the axis (E) is transmitted to the spring (D).

Avec un tel dispositif, la régulation du régime du moteur (3000 t /min) est effectuée par déformation appliquée au point (G) du levier d'ajustement. En augmentant la tension du ressort vers la position (G'), le régime maximum augmente. Si l'on diminue la tension du ressort en l'amenant en position (G"), le régime maximum du moteur diminue.  With such a device, the regulation of the engine speed (3000 rpm) is effected by deformation applied to the point (G) of the adjustment lever. By increasing the tension of the spring towards the position (G '), the maximum speed increases. If the tension of the spring is decreased by bringing it into position (G "), the maximum engine speed decreases.

De cette façon, on peut régler d'une manière permanente le régime du moteur et on peut opérer, selon les besoins, à un régime de moteur constant approprié pour le travail demandé et homologué.  In this way, it is possible to permanently adjust the engine speed and it is possible to operate, as required, at a constant engine speed suitable for the requested and approved work.

L'ensemble du dispositif de régulation est protégé des chocs extérieurs par les protections (H) et (H'). Le levier de basculement (C) est commandé par un ou des leviers verticaux de régulation (F) et (F").  The entire control device is protected from external shocks by the protections (H) and (H '). The tilting lever (C) is controlled by one or more vertical control levers (F) and (F ").

L'invention ainsi décrite ne se limite pas au mode de réalisation présenté à la figure. Elle englobe, sans limitation, les équivalents mécaniques de même structure ou de même fonction.  The invention thus described is not limited to the embodiment shown in the figure. It includes, without limitation, mechanical equivalents of the same structure or function.
