Abstract

The invention relates to a device which enables the vapours given off when filling a hydrocarbon tank to be evacuated. It consists of a head (1) comprising a housing (2) at its centre surmounted by a delivery lug (3) with air intake, two lateral discharge (evacuation) orifices (4) connected to two bent suction pipes (5). A helical spring (6) fixed to the head (1) holds the latter on the end of the nozzle (8). As the tank is being filled, a contact seal (7) ensures the temporary leaktightness of the device. The hydrocarbon vapours are then absorbed by the two lateral orifices (4) connected to the two bent suction pipes (5) which link up with an air extractor. By virtue of the housing (2), which has a bevelled internal edge, the head (1) can pivot in all directions. The device according to the invention is particularly designed for hydrocarbon pump nozzles in service stations.

Description

La présente invention concerne un dispositif anti-vapeur pour pistolet de pompe à hydrocarbure permettant, une fois relié par tuyaux à un extracteur d'air à colonnes, d'évacuer toute vapeur dégagée lors du remplissage d'un réservoir, évitant ainsi à l'usager de respirer des vapeurs nocives. The present invention relates to an anti-vapor device for a hydrocarbon pump gun allowing, once connected by pipes to an air extractor with columns, to evacuate any vapor released during the filling of a tank, thus avoiding the user to breathe noxious fumes.

Les dispositifs anti-vapeur existants sont indirects et donc placés dans un contexte global. Généralement, il s'agit, en intérieur, d'installer des extracteurs d'air chargés d'évacuer les vapeurs en renouvelant l'atmosphère ambiante. En extérieur, la ventilation des vapeurs dégagées lors du remplissage d'un réservoir est laissée au bon gré des conditions climatiques. Or, en été et en l'absence de vent, force est de constater que les vapeurs d'hydrocarbures augmentent et sont la cause de nombreuses nuisances pour l'usager des pompes. The existing anti-vapor devices are indirect and therefore placed in a global context. Generally, it involves, indoors, installing air extractors responsible for evacuating the vapors by renewing the ambient atmosphere. Outside, the ventilation of the vapors released during the filling of a tank is left according to the climatic conditions. However, in summer and in the absence of wind, it is clear that the hydrocarbon vapors increase and are the cause of many nuisances for the user of the pumps.

Le dispositif, selon l'invention, permet de remédier à cet inconvénient. Il comporte en effet, selon une première caractéristique, une tête plate, de forme circulaire, comprenant un logement central surmonte d'un oeilleton de refoulement, deux orifices latéraux d'évacuation reliés à deux tuyaux d'aspiration coudés dirigés vers I'extérieur et raccordés à un extracteur sHair à colonne montante. Lorsque la tête, à travers son logement central, est enfoncée sur le bec verseur d'un pistolet de pompe à hydracarbure, les vapeurs nocives sont évacuées par les deux orifices grâce au refoulement d'air provoqué par l'oeilleton. Un joint de contact circulaire, placé sur le bord intérieur de la tête, assure une étanchéité momentanée lors du remplissage d'un réservoir. The device according to the invention overcomes this drawback. It has in fact, according to a first characteristic, a flat head, of circular shape, comprising a central housing surmounted by a discharge eyelet, two lateral discharge orifices connected to two bent suction pipes directed towards the outside and connected to a sHair riser extractor. When the head, through its central housing, is pressed onto the pouring spout of a hydrocarbon pump gun, the harmful vapors are evacuated by the two orifices thanks to the air discharge caused by the eyecup. A circular contact seal, placed on the inner edge of the head, provides a temporary seal when filling a tank.

Le dispositif comporte, selon une seconde caractéristique, un logement central au chant intérieur biseauté comprenant un léger espace autour du pistolet pour permettre à la tête de pivoter dans tous les sens, offrant à l'usager, dans le cas du remplissage d'un réservoir mobile, un confort d'utilisation égal à celui apporté par un pistolet dépourvu d'un tel dispositif anti-vapeur. Un ressort hélicoïdal fixé sur la face extérieure de la tête du dispositif assure le maintien de celle-ci sur le bec verseur du pistolet. The device comprises, according to a second characteristic, a central housing with a bevelled inner edge comprising a slight space around the gun to allow the head to pivot in all directions, offering the user, in the case of filling a reservoir. mobile, comfort of use equal to that provided by a pistol devoid of such an anti-vapor device. A helical spring fixed on the external face of the head of the device ensures the maintenance of this one on the pouring spout of the gun.

Le dispositif comporte, selon l'invention, une troisième caractéristique, un oeilleton placé au-dessus du logement central de la tête permettant à l'usager, sans rompre l'étanchéité momentanée du dispositif, lors du remplissage d'un réservoir, de visualiser la montée du liquide dans celui-ci afin d'éviter tout débordement. The device comprises, according to the invention, a third characteristic, an eyecup placed above the central housing of the head allowing the user, without breaking the momentary tightness of the device, when filling a tank, to view the rise of the liquid in it in order to avoid any overflow.

Les dessins annexés illustrent l'invention
La figure 1 représente en vue de face le dispositif selon l'invention.The accompanying drawings illustrate the invention
Figure 1 shows a front view of the device according to the invention.

La figure 2 représente en coupe ce même dispositif. Figure 2 shows in section this same device.

En référence à ces dessins, le dispositif comporte une tête (1) plate de forme circulaire, comprenant en son centre un logement (2) surmonté d'un oeilleton de refoulement (3) assurant une prise d'air, deux orifices latéraux d'évacuation (4) reliés à deux tuyaux d'aspiration coudés (5). With reference to these drawings, the device comprises a flat head (1) of circular shape, comprising in its center a housing (2) surmounted by a discharge eyelet (3) ensuring an air intake, two lateral orifices of outlet (4) connected to two bent suction pipes (5).

Un ressort hélicoïdal (6) fixé à sa plus grande extrémité sur la face extérieure de la tête (1) maintient celle-ci sur le bec verseur du pistolet (8). Lors du remplissage d'un réservoir, un joint de contact (7) fixé sur la face intérieure de la tête (1) assure momentanément l'étan- chéité du dispositif. Les vapeurs d'hydrocarbure dégagées sont alors absorbées par les deux orifices latéraux d'évacuation (4) reliés aux deux tuyaux d'aspiration coudés (5) dirigés vers l'extérieur de la tête (1) et raccordés à un extracteur d'air à colonne montante (non représenté).A helical spring (6) fixed at its largest end on the outer face of the head (1) maintains the latter on the spout of the gun (8). When filling a tank, a contact seal (7) fixed on the inside of the head (1) temporarily seals the device. The released hydrocarbon vapors are then absorbed by the two lateral evacuation orifices (4) connected to the two bent suction pipes (5) directed towards the outside of the head (1) and connected to an air extractor riser (not shown).

Par l'entremise du logement (2), dont le chant intérieur est biseaute, laissant un léger espace autour du pistolet (8), la tête (1) peut pivoter dans tous les sens, facilitant en cas de remplissage d'un réservoir mobile, une utilisation appropriée dans de multiples positions.Through the housing (2), whose inner edge is beveled, leaving a slight space around the gun (8), the head (1) can pivot in all directions, making it easier to fill a mobile tank , suitable use in multiple positions.

Le dispositif, selon l'invention, est particulièrement destine à équiper sans modification préalable les pistolets de pompes à hydrocarbure des stations-services.  The device according to the invention is particularly intended to equip, without prior modification, the pistols of hydrocarbon pumps of service stations.
