Description

La présente invention concerne un pistolet pour la distribution de liquides volatiles à température ambiante, tels que l'essence ou analogues, qui permet de capter, éloigner et abattre les dégagements.The present invention relates to a gun for dispensing volatile liquids at room temperature, such as petrol or the like, which makes it possible to capture, distance and suppress the clearances.

Il est connu que de nombreuses substances liquides ont tendance à passer, rapidement et à la température ambiante, à l'état gazeux; parmi ces substances, on compte l'essence et de nombreux autres dérivés des hydrocarbures tels que les alcools, les ethers, les esters, les dérivés halogénés, etc.It is known that many liquid substances tend to pass, quickly and at room temperature, in the gaseous state; these substances include gasoline and many other derivatives of hydrocarbons such as alcohols, ethers, esters, halogenated derivatives, etc.

Il est également connu que les dégagements ou vapeurs de ces substances sont fortement toxiques et pour cette raison nocif pour l'organisme humain, autant au contact que, et par dessus tout par ingestion.It is also known that the releases or vapors of these substances are highly toxic and for this reason harmful to the human organism, as much in contact as, and above all by ingestion.

Il est de même connu que les pistolets employés actuellement pour la distribution des carburants et autres liquides volatiles toxiques, ne permettent pas la captation et l'abattage des dégagements.It is also known that the guns currently used for the distribution of fuels and other toxic volatile liquids do not allow capture and slaughter of the clearances.

Il apparait donc d'une grande importance et utilité, de pouvoir disposer d'un pistolet de distribution apte à capter, éloigner et abattre les dégagements de substances liquides toxiques.It therefore appears to be of great importance and usefulness, to be able to have a dispensing gun capable of capturing, removing and killing the release of toxic liquid substances.

Le but de la présente invention est de munir les pistoles de distribution de l'essence et d'autres hydrocarbures volatiles, de moyens appropriés à la captation, à l'écoulement et à l'abattage des dega- gements.The object of the present invention is to provide the pistols for distributing petrol and other volatile hydrocarbons with means suitable for capturing, flowing and slaughtering clearances.

Ce résultat est atteint en conformité avec l' invention en pourvoyant le tube de distribution du pistolet d'un embout externe et concentrique au tube, et lequel est ouvert à l'extrémité tournée vers l'embouchure du tube, l'autre extrémité étant reliée une chambre annulaire prévue à proximité de l'extrémité du tuyau flexible d'amenée du liquide et dans laquelle est engendrée une dépression.This result is achieved in accordance with the invention by providing the dispensing tube of the pistol with an external end concentric with the tube, which is open at the end facing the mouth of the tube, the other end being connected. an annular chamber provided near the end of the flexible liquid supply pipe and in which a vacuum is generated.

Les avantages obtenus grâce à l'invention consistent dans le fait que les dégagements sont captés tout autour du tube du pistolet de distribtu- tion, qu' il est possible d'abattre, c'est dire de condenser et de récupérer, les dégagements; qu' un pistolet ainsi réalisé est de construction simple, de manipulation facile, de fonctionnement sûr et de fiabilité très élevée. même après une longue période de fonctionnement sans interruption.The advantages obtained thanks to the invention consist in the fact that the clearances are captured all around the tube of the dispensing gun, which it is possible to knock down, that is to say to condense and recover, the clearances; that a pistol thus produced is of simple construction, easy handling, safe operation and very high reliability. even after a long period of uninterrupted operation.

Ces avantages et caractéristiques ainsi que d' autres, seront mieux compris de l'homme de l'art à la lumière de la description _qui va suivre et en référence aux dessins annexés, donnés à titre d' exemplification pratique de l'invention, mais à ne pas considérer au sens limitatif; et dans lesquels: la Fig. 1 représente la vue en plan d'un pistolet réalisé en conformité avec l'invention; la Fig. 2 représente la vue de coté du pistolet de la Fig. 1; la Fig. 3 est une vue en coupe suivant la ligne A-A de la Fig. 1; la Fig. 4 représente la vue d'ensemble d'un distributeur d'essence pour gare routière, équipé pour le pistolet de la Fig. 1.These advantages and characteristics, as well as others, will be better understood by those skilled in the art in the light of the description which follows and with reference to the appended drawings, given by way of practical exemplification of the invention, but not to be considered in the limiting sense; and in which: FIG. 1 shows the plan view of a pistol produced in accordance with the invention; Fig. 2 shows the side view of the pistol in FIG. 1; Fig. 3 is a sectional view along line A-A of FIG. 1; Fig. 4 represents the overall view of a petrol dispenser for a bus station, equipped for the gun of FIG. 1.

Réduit sa structure essentielle et en référence aux dessins annexés, un pistolet pour la distribution de l'essence avec captation des dégagements ou vapeurs selon l'invention, comprend un corps 1 comportant une poignée et une manette 2 de commande de la distribution du liquide à travers un conduit 11, une extrémité dudit corps 1 étant pourvue d'un tube métallique 3 de raccordement au tube 4 d'amenée du liquide à partir du distributeur D et l'autre extrémité étant pourvue d'un tube 5 à introduire dans l'embouchure du réservoir du véhicule automobile ravitailler. Autour et concentrique la base dudit tube 5, un embout ou ajutage 6 est relié, au moyen d'un petit tube 7 à une chambre annulaire 8, ménagée autour du tube métallique 3 précité et reliée à son tour, au moyen d'un tuyau flexible 9, à un ventilateur aspirant V asservi un moteur éléctrique M et dont la décharge 10 dans l'atmosphère est disposée à une distance convenable du distributeur D. En conformité avec l'inventon, il est également prévu que le dispositif d'écoulement 10 soit pourvu d'un filtre ou condensateur ou autre moyen connu, pour obtenir l'abattage des substances toxiques et émetre ainsi dans l'atmosphère, de l'air propre. La mise en oeuvre du moteur électrique M est contrôlée et régulée, avec des moyens éiéctriques connus en soi, par le distributeur D lui-même pour la durée de la distribution de l'essence.Reduces its essential structure and with reference to the accompanying drawings, a pistol for the distribution of petrol with capture of the releases or vapors according to the invention, comprises a body 1 comprising a handle and a handle 2 for controlling the distribution of the liquid to through a conduit 11, one end of said body 1 being provided with a metal tube 3 for connection to the tube 4 for supplying the liquid from the distributor D and the other end being provided with a tube 5 to be introduced into the motor vehicle tank mouth refuel. Around and concentric the base of said tube 5, a nozzle or nozzle 6 is connected, by means of a small tube 7 to an annular chamber 8, formed around the aforementioned metal tube 3 and connected in turn, by means of a pipe flexible 9, to a suction fan V controlled by an electric motor M and the discharge 10 of which into the atmosphere is arranged at a suitable distance from the distributor D. In accordance with the invention, provision is also made for the flow device 10 either provided with a filter or condenser or other known means, to obtain the slaughter of toxic substances and thus emit into the atmosphere, clean air. The implementation of the electric motor M is controlled and regulated, with electric means known per se, by the distributor D itself for the duration of the distribution of the petrol.

Le fonctionnement est le suivant. En décrochant le pistolet du distributeur D, l'éieciroventilateur V entre en action, de sorte que, à peine actionnée la manette, pendant que l'essence sort du tube 5, l'air externe qui se trouve autour du tube 5 est aspiré dans l'embout 6, captant ainsi les vapeurs d'essence, lesquelles sont abattues par l'épurateur F, déchargeant ainsi dans l'atmosphère de l'air propre à travers le tube d'écoulement 10.The operation is as follows. By unhooking the gun from the distributor D, the fan V comes into action, so that, barely actuated the lever, while the petrol leaves the tube 5, the external air which is around the tube 5 is drawn into the nozzle 6, thus capturing the gasoline vapors, which are shot down by the purifier F, thus discharging clean air into the atmosphere through the flow tube 10.
