Description
La présente invention concerne les dispositifs électromécaniques comportant une bobine et un élément mobile sous l’effet du champ magnétique de la bobine, et plus particulièrement mais non exclusivement les électrovannes dites de purge canister utilisées dans le domaine automobile intégrant un dispositif de récupération des bavures de soudure.The present invention relates to electromechanical devices comprising a coil and a movable element under the effect of the magnetic field of the coil, and more particularly but not exclusively the so-called canister purge solenoid valves used in the automotive field integrating a device for recovering burrs from welding.
Le réservoir des véhicules à moteur thermique est muni d’un filtre à charbon actif appelé canister qui absorbe et retient les vapeurs de carburant provenant du réservoir.The tank of combustion engine vehicles is equipped with an activated carbon filter called a canister which absorbs and retains the fuel vapors coming from the tank.
Le canister est relié à l’admission du moteur via une électrovanne de purge qui est fermée lorsque le moteur est à l’arrêt et qui s’ouvre de façon à permettre la purge du filtre lorsque le moteur est en fonctionnement.The canister is connected to the engine intake via a purge solenoid valve which is closed when the engine is stopped and which opens to allow the filter to be purged when the engine is running.
De façon conventionnelle, le dispositif électromagnétique comporte un noyau fixe creux en un matériau ferromagnétique s’étendant selon un axe, une bobine montée autour du noyau fixe et un élément d’obturation, mobile selon l’axe du noyau fixe sous l’effet du champ magnétique généré par la bobine. L’ensemble de ces éléments est disposé dans un corps fermé par un couvercle.Conventionally, the electromagnetic device comprises a hollow fixed core made of a ferromagnetic material extending along an axis, a coil mounted around the fixed core and a shutter element, movable along the axis of the fixed core under the effect of the magnetic field generated by the coil. All of these elements are placed in a body closed by a lid.
Afin d’assurer l’étanchéité, nécessaire au fonctionnement du dispositif électromagnétique, dans le corps, le couvercle est soudé au corps.In order to ensure the tightness, necessary for the operation of the electromagnetic device, in the body, the cover is welded to the body.
Un inconvénient de la soudure provient de la formation des bavures qui sont susceptibles de se répandre dans toutes les cavités du dispositif électromagnétique et l’endommager.A disadvantage of welding comes from the formation of burrs which are likely to spread into all the cavities of the electromagnetic device and damage it.
La présente invention a donc pour objet de pallier un ou plusieurs des inconvénients des dispositifs de l’art antérieur en proposant un dispositif électromécanique permettant d’éviter aux bavures de se répandre à l’intérieur du dispositif.The object of the present invention is therefore to overcome one or more of the drawbacks of the devices of the prior art by proposing an electromechanical device making it possible to prevent burrs from spreading inside the device.
Pour cela, la présente invention propose un dispositif électromécanique (1) comportant un corps dans lequel est disposé un système électromagnétique, et comportant une pièce 83 de fermeture du corps, la pièce de fermeture étant fixée au corps par soudure et le dispositif comportant un élément de récupération qui permet de récupérer les bavures de soudure:For this, the present invention proposes an electromechanical device (1) comprising a body in which an electromagnetic system is arranged, and comprising a part 83 for closing the body, the closing part being fixed to the body by welding and the device comprising an element recovery which allows to recover welding burrs:
De cette façon les bavures ne se répandent pas à l’intérieur du corps du dispositif électromagnétique.In this way, the burrs do not spread inside the body of the electromagnetic device.
Selon un mode de réalisation de l’invention, l’élément de récupération est formé par un canal disposé dans la partie du corps en contact avec la pièce de fermeture.According to one embodiment of the invention, the recovery element is formed by a channel arranged in the part of the body in contact with the closure part.
Selon un mode de réalisation de l’invention, l’élément de récupération est formé à l’intérieur du corps.According to one embodiment of the invention, the recovery element is formed inside the body.
Selon un mode de réalisation de l’invention, l’élément de récupération est formé sur une partie du pourtour du corps.According to one embodiment of the invention, the recovery element is formed on a part of the circumference of the body.
Selon une variante de réalisation de l’invention, l’élément de récupération est formé par une pièce disposée dans le canal.According to a variant embodiment of the invention, the recovery element is formed by a part placed in the channel.
Selon un mode de réalisation de l’invention, le pourtour intérieur du canal comporte une languette permettant la fixation de l’élément de fermeture sur le corps du dispositif électromagnétique.According to one embodiment of the invention, the inner periphery of the channel comprises a tongue allowing the fixing of the closure element on the body of the electromagnetic device.
Selon un mode de réalisation de l’invention, le dispositif est une électrovanne de purge canister.According to one embodiment of the invention, the device is a canister purge solenoid valve.

La pièce 30 de fermeture est un couvercle. L’embout de sortie 11 conduit comporte à sa base une tuyère. Cette tuyère forme un conduit interne 111 qui sert à optimiser le flux et le débit des vapeurs de carburant évacuées. C’est donc la tuyère 111 qui se prolonge sous la forme de l’embout 11 de sortie des vapeurs de carburant.According to one embodiment of the invention, the solenoid valve is connected to inlet and outlet ducts, not shown, by means of respective outlet 11 and inlet 12 endpieces. According to one embodiment, the endpiece 12 is molded with the body 20 of the solenoid valve, made of plastic material, and the end piece 11 with a closure piece 30 which is attached to the body 20 and closes it. The closing part 30 is a lid. The conduit outlet end piece 11 has a nozzle at its base. This nozzle forms an internal duct 111 which serves to optimize the flow and the flow rate of the fuel vapors evacuated. It is therefore the nozzle 111 which is extended in the form of the nozzle 11 for the fuel vapor outlet.
Selon un mode de réalisation de l’invention, l’électrovanne 1 comporte un connecteur 21 pour son raccordement électrique.According to one embodiment of the invention, the solenoid valve 1 comprises a connector 21 for its electrical connection.
L’électrovanne 1 est, dans l’exemple considéré, fermée au repos, et s’ouvre lorsqu’elle est alimentée électriquement, par exemple à une tension DC comprise entre 10 et 15V. Les matériaux de l’électrovanne sont choisis pour résister aux vapeurs d’hydrocarbures, notamment d’essence.The solenoid valve 1 is, in the example considered, closed at rest, and opens when it is electrically powered, for example at a DC voltage of between 10 and 15V. The materials of the solenoid valve are chosen to resist hydrocarbon vapors, especially gasoline.
Selon un mode de réalisation de l’invention, le corps 20 de l’électrovanne 1 comprend intérieurement un système électromagnétique disposé dans le corps. Ce système électromagnétique comporte, un noyau fixe 41, tubulaire d’axe X, réalisé en un matériau ferromagnétique doux tel que par exemple du fer ou un acier ferromagnétique.According to one embodiment of the invention, the body 20 of the solenoid valve 1 internally comprises an electromagnetic system arranged in the body.

La pièce 82 est un récipient.According to a variant embodiment of the invention, the recovery element 80 is formed by a part 82 placed in the channel 81. The part 82 is a container.
Dans le cadre de l’invention, le pourtour 211 intérieur du canal 81 dépasse du pourtour 212 extérieur de façon à former une languette 90. L’extrémité 91 de cette languette est écrasée contre la pièce 30 de fermeture lors de la soudure et permet ainsi la fixation de la pièce 30 de fermeture sur le corps 20 du dispositif 1 électromagnétique.In the context of the invention, the inner periphery 211 of the channel 81 protrudes from the outer periphery 212 so as to form a tongue 90. The end 91 of this tongue is crushed against the closing part 30 during welding and thus allows fixing the closure piece 30 on the body 20 of the electromagnetic device 1.
Selon un mode de réalisation de l’invention, la face interne 92 de la languette 90 repose contre un rebord 31 de la pièce 30 de fermeture. La face interne 92 de la languette 90 est la face orientée vers l’intérieur du corps 20 du dispositif. L’intérieur du corps correspond à la cavité 22 formée par le corps dans laquelle est disposé le système électromagnétique. Ainsi lorsque l’extrémité 91 est écrasée pendant la soudure, les bavures ne peuvent pas tomber à l’intérieur du corps 20 du dispositif 1 électromagnétique.According to one embodiment of the invention, the inner face 92 of the tab 90 rests against a rim 31 of the part 30 of closure. The internal face 92 of the tab 90 is the face facing the inside of the body 20 of the device. The interior of the body corresponds to the cavity 22 formed by the body in which the electromagnetic system is arranged. Thus when the end 91 is crushed during welding, the burrs cannot fall inside the body 20 of the electromagnetic device 1.
La portée de la présente invention ne se limite pas aux détails donnés ci-dessus et permet des modes de réalisation sous de nombreuses autres formes spécifiques sans s'éloigner du domaine d'application de l'invention. Par conséquent, les présents modes de réalisation doivent être considérés à titre d'illustration, et peuvent être modifiés sans toutefois sortir de la portée définie par les revendications.The scope of the present invention is not limited to the details given above and allows embodiments in many other specific forms without departing from the scope of the invention. Therefore, the present embodiments should be considered by way of illustration, and can be modified without departing from the scope defined by the claims.
