Description

La présente invention concerne un distributeur d'allumage pour moteur à combustion interne du type comportant, dans leur ordre successif de montage ; un boitier fixé directement sur le carter du moteur ; une membrane d'étanchéité coiffant le boitier ; un rotor de distribution dont l'embase traverse la membrane et le fond du boitier pour se monter en bout de villebrequin ou d'arbre à came ; une tête de distribution formant le boitier en pinçant la membrane.The present invention relates to an ignition distributor for an internal combustion engine of the type comprising, in their successive assembly order; a housing fixed directly to the motor housing; a waterproofing membrane covering the case; a distribution rotor, the base of which crosses the membrane and the bottom of the housing to be mounted at the end of the crankshaft or camshaft; a dispensing head forming the housing by pinching the membrane.

Dans les distributeurs connus de ce type l'inconvénient majeur Iréside dans l'obligation de devoir stocker le distributeur en pièces détachées et l'assembler sur le véhicule proprement dit, cela du fait de la présence de la membrane dont le montage sur le boitier doit s'effectuer nécessairement avant le montage du rotor qui la traverse. Or la présence de la membrane est d'autant plus indispensable, lors d'un montage en bout de villebrequin, que son rôle n'est plus seulement de protéger contre la poussière, mais également de constituer un écran aux échanges thermiques entre une chambre froide constituée par la tête soumise aux intempéries et une chambre chaude constituée par le boitier et subissant l'influence de la température du moteur par conduction. Ces échanges de températures favoriseraient la condensation à l'intérieur de la tête, ce qui serait néfaste au bon fonctionnement de l'allumage. La présente invention a pour but de remédier à ces inconvénients et concerne à cet effet un distributeur d'allumage pour moteur à combustion interne du type comportant un boitier fixé directement sur le carter du moteur ; une membrane d'étanchéité coiffant le boitier ; un rotor de distribution dont l'embase traverse la membrane et le fond du boitier pour se monter en bout de villebrequin ou d'arbre à came ; une tête de distribution fermant le boitier en pinçant la membrane caractérisé en ce que la membrane d'étanchéité est constituée par un diaphragme pincé entre le boitier et la tête préalablement assemblés et composés d'une pluralité de lamelles élastiquement déformables qui issuent d'une collerette circulaire, convergent vers l'axe XX' du distributeur et s'escamottent au passage du rotor préalablement monté en bout d'arbre à came ou de villebrequin pour se reformer ensuite autour de l'embase dudit rotor.In known distributors of this type, the major drawback I resides in the obligation to have to store the distributor in spare parts and assemble it on the vehicle proper, this due to the presence of the membrane, the mounting of which on the housing must necessarily be done before mounting the rotor passing through it. However, the presence of the membrane is all the more essential, during assembly at the end of the crankshaft, since its role is no longer only to protect against dust, but also to constitute a screen for heat exchanges between a cold room. constituted by the head subjected to bad weather and a hot chamber constituted by the case and undergoing the influence of the temperature of the engine by conduction. These temperature exchanges would promote condensation inside the head, which would be detrimental to the proper functioning of the ignition. The object of the present invention is to remedy these drawbacks and to this end relates to an ignition distributor for an internal combustion engine of the type comprising a box fixed directly to the engine casing; a waterproofing membrane covering the case; a distribution rotor, the base of which crosses the membrane and the bottom of the housing to be mounted at the end of the crankshaft or camshaft; a dispensing head closing the housing by pinching the membrane characterized in that the sealing membrane is constituted by a diaphragm pinched between the housing and the head previously assembled and composed of a plurality of elastically deformable lamellae which emit from a flange circular, converge towards the XX 'axis of the distributor and retract with the passage of the rotor previously mounted at the end of the camshaft or of the crankshaft to then reform around of the base of said rotor.

Le distributeur.d'allumage pour moteur a combustion interne représenté sur les figures comporte dans leur ordre successif de montage : un boitier 1 fixé directement sur le carter 2 du moteur par l'intermédiaire de vis de fixation 3 traversant des pattes 4 obtenues de moulage avec le corps dudit boitier 1 dont le fond 5 comporte une ouverture 6 permettant lors du montage le passage de l'extrémité 7 de l'arbre à came 8 ; une membrane d'étanchéité 9 coiffant le boitier 1 ; un rotor de distribution 10 dont l'embase 11 traverse la membrane 9 et l'ouverture 6 dù fond 5 du boitier 1 pour venir coiffer l'extrémité 7 de l'arbre à came 8 avec lequel il est solidarisé en rotation et positionné grâce à une clavette 12 obtenue de moulage dans l'alésage 13 de l'embase 11 du rotor 10 et se logeant dans un logement correspondant 14 ménagé sur l'arbre 8 ; une tête de distribution 15 fermant le boitier 1, en pinçant la membrane 9, par l'intermédiaire de vis de fixation 16 traversant des pattes 17 obtenues de moulage avec la tête 15 et se revissant dans les trous filetés 18 de deux pattes 19 obtenues de moulage avec le boitier 1.The ignition distributor for an internal combustion engine shown in the figures comprises in their successive assembly order: a box 1 fixed directly to the casing 2 of the engine by means of fixing screws 3 passing through lugs 4 obtained by molding with the body of said case 1, the bottom 5 of which has an opening 6 allowing the passage of the end 7 of the camshaft 8 during assembly; a sealing membrane 9 covering the case 1; a distribution rotor 10, the base 11 of which crosses the membrane 9 and the opening 6 of the bottom 5 of the housing 1 to cover the end 7 of the camshaft 8 with which it is secured in rotation and positioned thanks to a key 12 obtained by molding in the bore 13 of the base 11 of the rotor 10 and being housed in a corresponding housing 14 formed on the shaft 8; a dispensing head 15 closing the housing 1, by pinching the membrane 9, by means of fixing screws 16 passing through lugs 17 obtained by molding with the head 15 and screwing back into the threaded holes 18 of two lugs 19 obtained from molding with the box 1.

La membrane d'étanchéité 9 est constituée par un diaphragme pincé entre le boitier 1 et la tête 15 et composé d'une pluralité de lamelles 20 élastiquement déformables dont leur base 21 se confond avec une collerette circulaire 22 et ont une souplesse suffi - santé pour qu'elles puissent s'escamoter au passage du rotor 10 préalablement monté en bout d'arbre à came 8 pour se reformer ensuite autour de l'embase 11 dudit rotor 10, ceci afin de permettre le préassemblage de l'ensemble tête-membrane- boitier.The sealing membrane 9 is constituted by a diaphragm pinched between the housing 1 and the head 15 and composed of a plurality of elastically deformable strips 20, their base 21 merges with a circular collar 22 and have sufficient flexibility - health for that they can be retracted on passage of the rotor 10 previously mounted at the end of the camshaft 8 in order to then reform around the base 11 of said rotor 10, this in order to allow the preassembly of the head-membrane-housing assembly.

Selon un mode préférentiel de réalisation, la membrane 9 est obtenue par moulage de matière plastique et les lamelles 20 constituant le diaphragme sont des secteurs dont les axes OY convergent vers l'axe XX' du distributeur et se confondent avec les génératrices d'un cône formant un α angle avec le plan de la collerette 22.According to a preferred embodiment, the membrane 9 is obtained by molding of plastic material and the strips 20 constituting the diaphragm are sectors whose axes OY converge towards the axis XX 'of the distributor and merge with the generatrices of a cone forming an angle α with the plane of the collar 22.

Les bords latéraux 23 des lamelles 20 en forme de secteur sont approximativement jointifs si on néglige le jeu 24 permettant la séparation des secteurs qui peut également être effectuée par découpe ultérieure.The lateral edges 23 of the sector-shaped strips 20 are approximately contiguous if one neglects the clearance 24 allowing the separation of the sectors which can also be carried out by subsequent cutting.

La membrane 9 comporte également un évidement 25 pratiqué sur sa collerette 22 permettant le logement d'un ergot de centrage 27 de la tête 15 permettant le positionnement de cette dernière par rapport au boitier 1.The membrane 9 also includes a recess 25 formed on its flange 22 allowing the housing of a centering lug 27 of the head 15 allowing the positioning of the latter relative to the housing 1.

En outre la partie inférieure de la collerette 22 comporte un rebord annulaire 28 se logeant élastiquement dans l'alésage 29 du boitier 1 pour assurer l'étanchéité et son maintien en cours de montage.In addition, the lower part of the flange 22 has an annular rim 28 which is resiliently housed in the bore 29 of the housing 1 to seal and maintain it during assembly.

Le mode de réalisation de la membrane 30 représenté aux figures 5 et 6 différe essentiellement du précédent en ce que le diaphragme la constituant est. composé de lamelles 31 en forme de secteur se chevauchant partiellement.The embodiment of the membrane 30 shown in Figures 5 and 6 differs essentially from the previous in that the diaphragm constituting it. composed of lamellae 31 in the form of a partially overlapping sector.

Pour obtenir ce résultat on réalise d'abord une membrane 30 dont les bords latéraux 32 des lamelles 31 A en forme de secteur fictivement représentées, sont dans un premier temps jointifs comme précédemment mais dont l'ongle β formé avec le plan de la collerette 33 est plus grand que l'angle α à obtenir d'où un angle au sommet du cône engendré par les axes OZ des secteurs 31, plus petit que précédemment .To obtain this result, a membrane 30 is first produced, the lateral edges 32 of the lamellas 31 A in the form of a fictitiously represented sector, are initially joined as previously but whose nail β formed with the plane of the collar 33 is greater than the angle α to be obtained, hence an angle at the top of the cone generated by the axes OZ of the sectors 31, smaller than previously.

De cela il en résulte, pour une même longueur L que précédemment, une largeur plus importante de l'extrémité libre 31a des secteurs 31. Cela impliquera nécessairement un recouvrement partiel des lamelles 31 entre elles lors de leur mise en forme définitive, suivant l'angle α, par conformation à chaud ultérieure.This results, for the same length L as previously, a greater width of the free end 31a of the sectors 31. This will necessarily imply a partial overlap of the strips 31 between them during their final shaping, according to the angle α, by subsequent hot conformation.

L'angle initial/adonné aux lamelles 31 A par rapport au plan de.b collerette 33 peut bien entendu être plus important et tendre vers la perpendicularité.The initial angle / given to the slats 31 A with respect to the plane of the collar 33 can of course be greater and tend towards perpendicularity.

Dans ce cos les lamelles 31 B fictivement représentées ne sont plus initialement jointives mais positivement écartées les unes des outres mais elles se chevaucheront de la même manière lors de leur conformation à chaud ultérieure suivant l'angle α à obtenir.In this cos the lamellas 31 B fictitiously represented are no longer initially contiguous but positively separated from each other wineskins but they will overlap in the same way during their subsequent hot conformation according to the angle α to be obtained.
