Abstract

At the edge of the distributor housing is secured a cap, held by two springs, whose one end section is bent. The springs are fitted in a depression of the housing, radially swivellably in a distributor shaft plane secured against loosening. The depression is formed by an annular groove in the housing wall. After the spring insertion, pref. a protrusion is provided in one edge, partic. by upsetting. The protrusion is formed on the spring sides over its width. One end section of the spring may be bent to form a sleeve, while the annular groove may be of rectangular cross section. The end section of the sleeve abuts the groove flank, adjacent the housing edge, the protrusions being formed in the groove flank opposite the edge.

Description

Distributeur d'allumage pour moteurs à combustion
interne ".
Ignition distributor for combustion engines
internal ".

L'invention concerne un distributeur d'allumage pour moteurs à combustion interne avec un boîtier et avec un capot susceptible d'être fixé sur le bord de ce boitier au moyen d'au moins deux ressorts de retenue, une extrémité des ressorts étant repliée et disposee de façon imperdable dans un logement du boîtier avec pivotement dans un plan radial par rapport à l'arbre du distributeur d'allumage. Un tel distributeur d'allumage est connu par le document DE GM 19 62 301, distributeur dans lequel une patte faisant saillie hors du boîtier constitue avec un voile médian et un appendice, le logement de l'étrier de retenue. Les deux pattes compliquent l'outillage de moulage sous pression du bottier et augmentent le déchet lors de la coulée du boîtier. The invention relates to an ignition distributor for internal combustion engines with a housing and with a cover capable of being fixed to the edge of this housing by means of at least two retaining springs, one end of the springs being folded back and arranged captively in a housing of the housing with pivoting in a radial plane relative to the shaft of the ignition distributor. Such an ignition distributor is known from the document DE GM 19 62 301, a distributor in which a tab protruding from the housing constitutes, with a median web and an appendage, the housing of the retaining stirrup. The two tabs complicate the die-casting tool of the shoemaker and increase the waste when the casing is poured.

La présente invention a pour objet un distributeur d'allumage pour moteurs à combustion interne caractérisé en ce que le logement (rainure annulaire) dans la paroi du boîtier est évidé, tandis qu'après l'insertion du ressort de retenue dans le logement il est formé, de préférence sur un seul des bords de ce logement, une saillie de chaque côté du ressort de retenue ainsi qu'une saillie sur le côté large de ce ressort, notamment par matage. The present invention relates to an ignition distributor for internal combustion engines characterized in that the housing (annular groove) in the wall of the housing is hollowed out, while after the insertion of the retaining spring in the housing it is formed, preferably on only one of the edges of this housing, a projection on each side of the retaining spring as well as a projection on the wide side of this spring, in particular by stamping.

Cette disposition permet-un outillage simple de moulage sous pression du boîtier et un déchet réduit. En outre, grâce au matage, le montage du ressort de retenue dans le boîtier peut être automatisé. This arrangement allows a simple tool for die-casting of the housing and reduced waste. In addition, thanks to the matting, the mounting of the retaining spring in the housing can be automated.

Des perfectionnements avantageux de l'invention sont décrits dans la suite. Conformément à l'invention, une rainure annulaire dans la paroi du boîtier constitue les deux logements. Ainsi, l'outillage de moulage sous pression présente de façon souhaitable une symétrie de révolution au voisinage des ressorts de retenue et ces ressorts de retenue peuvent être fixés sur la totalité de la péripfrérie du boîtier. La configuration simple de la douille réalisable par roulage et de la section transversale de la rainure, simplifie davantage encore le processus de réalisation. Une fixation sûre et facile à réaliser des ressorts de retenue est obtenue par le fait que la zone d'extrémité de la douille s'applique sur le flanc voisin du bord du boîtier, de la rainure annulaire, tandis que les saillies sont disposées sur le bord du flanc opposé de la rainure. Advantageous improvements of the invention are described below. According to the invention, an annular groove in the wall of the housing constitutes the two housings. Thus, the die-casting tool desirably has a symmetry of revolution in the vicinity of the retaining springs and these retaining springs can be fixed to the entire periphery of the housing. The simple configuration of the rollable socket and the cross section of the groove further simplifies the production process. A secure and easy fixing of retaining springs is obtained by the fact that the end zone of the sleeve is applied to the flank near the edge of the housing, of the annular groove, while the projections are arranged on the edge of the opposite flank of the groove.

Un exemple de réalisation de l'invention est représenté sur les dessins ci-joints et expliqué plus en détail ci-après
- la figure 1 représente en coupe axiale partielle et grandeur nature, un distributeur d'allumage, conforme à l'invention,
- la figure 2 est un détail selon II de la figure 1 à échelle agrandie,
- la figure 3 montre le même détail mais en perspective et sans ressort de retenue,
Le distributeur d'allumage de la figure l comprend un boîtier 10 en métal léger réalisé par un procédé de moulage sous pression, un arbre ll monté sur ce bolier et un capot 12 en matière isolante qui est susceptible d'être fixé sur un bord 14 du boîtier 10 avec interposition d'une calotte 13.Le boltier 10 est fixé sur le moteur à combustion interne 15 (d'une façon non représentée) et l'arbre ll est relié à une pièce d'accouplement, (non représentée) de l'arbre à cames.
An exemplary embodiment of the invention is shown in the accompanying drawings and explained in more detail below
FIG. 1 represents a partial axial section and full size, an ignition distributor, in accordance with the invention,
FIG. 2 is a detail along II of FIG. 1 on an enlarged scale,
- Figure 3 shows the same detail but in perspective and without retaining spring,
The ignition distributor of FIG. 1 comprises a light metal housing 10 produced by a pressure molding process, a shaft 11 mounted on this bolier and a cover 12 made of insulating material which is capable of being fixed on an edge 14 of the housing 10 with the interposition of a cap 13. The bolt bowl 10 is fixed to the internal combustion engine 15 (in a manner not shown) and the shaft ll is connected to a coupling part, (not shown) of the camshaft.

La- fixation amovible du capot 12 sur le boîtier 10 s'effectue par l'intermédiaire de deux ressorts de retenue 16 en bande.d'acier, qui sont susceptibles de pivoter dans un plan radial par rapport à l'axe 18 de l'arbre 11. La- removable fixing of the cover 12 on the housing 10 is effected by means of two retaining springs 16 in strip steel, which are capable of pivoting in a radial plane relative to the axis 18 of the tree 11.

Une des parties d'extrémité des ressorts de retenue 16 est repliée pour former une douille annulaire 17 et est insérée dans une rainure annulaire 19 de la paroi 20 du boîtier 10. L'autre partie d'extrémité 21 s'enclenche dans une gorge 22 du capot 12. Les ressorts de retenue 16 peuvent pivoter selon la flèche 9 à partir de leur position de fixation représentée dans leur position libre.One of the end parts of the retaining springs 16 is folded back to form an annular sleeve 17 and is inserted into an annular groove 19 in the wall 20 of the housing 10. The other end part 21 engages in a groove 22 of the cover 12. The retaining springs 16 can pivot according to arrow 9 from their fixing position shown in their free position.

Les figures 2 et 3 montrent la paroi 20 du boitier 10 dans laquelle est formée la rainure annulaire 19 avec une section transversale carrée. La zone d'extrémité 23 de la douille 17 s'applique sur le flanc 24 de la rainure voisin du bord 14. Après la mise en place du ressort de retenue 16 (figure 2) dans la rainure annulaire 19, on forme sur le bord 27 une saillie 25 de chaque côté du ressort de retenue 16 ainsi qu'une saillie 26 sur le côté large de ce ressort, et ceci de préférence par matage radial dans le flanc 28, opposé au bord 14 du boîtier 10, de la rainure. Figures 2 and 3 show the wall 20 of the housing 10 in which is formed the annular groove 19 with a square cross section. The end region 23 of the sleeve 17 is applied to the side 24 of the groove close to the edge 14. After the positioning of the retaining spring 16 (FIG. 2) in the annular groove 19, the edge is formed 27 a projection 25 on each side of the retaining spring 16 as well as a projection 26 on the wide side of this spring, and this preferably by radial stamping in the sidewall 28, opposite the edge 14 of the housing 10, of the groove.

La fixation imperdable et permettant le pivotement des deux ressorts de retenue 16 dans le boîtier 10 s'effectue sans pièces supplémentaires et peut être réalisée simplement selon un proces-sus de montage complè dément automatisé.  The captive fixing and allowing the pivoting of the two retaining springs 16 in the housing 10 is carried out without additional parts and can be carried out simply according to a completely automated mounting process.
