Abstract

The invention relates to a ventilation device according to one of claims 1 to 4 of the main patent, in which the shut-off valve 4 comprises a flap 15 returned against a seat by a spring 6 and comprising a pusher 5 subjected to the action of the filling nozzle. The device according to the invention is characterised in that a cage 16 equipped with a seal 17 interacting with a seat 21 of the ventilation pipe 3 is mounted so as to slide on the said flap 15 and contains a ball 18 lodged by gravity on inclined planes 20 of the said flap 15. Application to the automotive industry.

Description

La présente addition concerne un perfectionnement au dispositif de ventilation selon l'une des revendications 1 à 4 du brevet principal. Elle a trait à des moyens d'obturation du circuit de ventilation en cas de retournement du véhicule.The present addition relates to an improvement to the ventilation device according to one of claims 1 to 4 of the main patent. It relates to means for closing the ventilation circuit in the event of the vehicle overturning.

A cet effet, le dispositif selon la présente addition, dans lequel la valve d'obturation comprend un clapet rappelé contre un siège par~ un ressort et comportant un poussoir soumis à l'action du pistolet de remplissage, est caractérisé par le fait qu'une cage munie d'une garniture d'étanchéité coopérant avec un siège de la tubulure de ventilation est montée coulissante sur ledit clapet et contient une bille logée par gravité sur des plans inclinés dudit clapet.To this end, the device according to the present addition, in which the shutter valve comprises a valve biased against a seat by ~ a spring and comprising a plunger subjected to the action of the filling gun, is characterized in that a cage provided with a seal fitting cooperating with a seat of the ventilation pipe is slidably mounted on said valve and contains a ball housed by gravity on inclined planes of said valve.

Lorsque le véhicule est vertical, la bille appuie par gravité sur la cage coulissante et écarte le joint d'étanché- ité qu'elle porte du siège de la tubulure d'étanchéité qui est ainsi ouverte. En cas de renversement du vehicule, la bille glisse contre l'un ou l'autre des plans inclinés du clapet et deplace la cage dont le joint d'etanchéité vient s'appliquer contre le siège de la tubulure qui est ainsi obturée.When the vehicle is vertical, the ball presses by gravity on the sliding cage and separates the seal it carries from the seat of the sealing tube which is thus opened. In the event of the vehicle overturning, the ball slides against one or other of the inclined planes of the valve and moves the cage, the seal of which comes to bear against the seat of the tube which is thus closed.

L'invention sera bien comprise à la lecture de la description suivante faite en se référant au dessin annexé dans lequel: - la figure 1 est une vue schématique en coupe du dispositif d'obturation pour un véhicule en position verticale, et - la figure 2 est analogue à la figure 1 pour le véhicule en position inclinée.The invention will be clearly understood on reading the following description made with reference to the accompanying drawing in which: - Figure 1 is a schematic sectional view of the shutter device for a vehicle in a vertical position, and - Figure 2 is similar to FIG. 1 for the vehicle in an inclined position.

Dans la position de fonctionnement normal de la figure 1 le ressort 6 plaque le joint d'étanchéité 14, solidaire du corps de clapet 15 dont dépasse le poussoir 5, contre son siège, ce qui assure l'étanchéité de la tubulure de remplissage 7.In the normal operating position of FIG. 1, the spring 6 presses the seal 14, integral with the valve body 15 of which protrudes the pusher 5, against its seat, which seals the filling nozzle 7.

Une cage 16, portant un joint d'étanchéité 17, est montée libre sur le corps de clapet 15 et contient une bille 18. A cage 16, carrying a seal 17, is freely mounted on the valve body 15 and contains a ball 18.

Au repos, la bille 18 repose sur le fond 19 de la cage 16 et est maintenue latéralement par deux plans inclinés 20 solidaires du corps 15. Le poids de la bille 18 appuie la cage 16 contre le corps de clapet 15 et le joint d'etanchéité 17 est écarté de son siège 21 sur l'entrée de la tubulure 3. (figure 1).At rest, the ball 18 rests on the bottom 19 of the cage 16 and is held laterally by two inclined planes 20 integral with the body 15. The weight of the ball 18 presses the cage 16 against the valve body 15 and the gasket. sealing 17 is spaced from its seat 21 on the inlet of the tubing 3. (Figure 1).

En cas de renversement du véhicule (figure 2), la bille 18 roule sur l'un des plans inclinés 20 en écartant la cage 16 du corps de clapet 15, de sorte que le joint d'étanchéité 17 vient se plaquer sur son siège 21 et obturer la tubulure de ventilation 3.. L'étanchéité avec la tubulure de remplissage reste assurée par l'action du ressort 6 sur le corps de clapet 15. In the event of the vehicle overturning (FIG. 2), the ball 18 rolls on one of the inclined planes 20 by moving the cage 16 away from the valve body 15, so that the seal 17 is pressed against its seat 21 and close the ventilation pipe 3 .. The tightness with the filling pipe remains ensured by the action of the spring 6 on the valve body 15.
