Description
DISPOSITIF DE FERMETURE ET DE SECURITE POUR TOUS RECIPIENTS
DESTINES A LA CUISSON SOUS PRESSION, DITS AUTOCUISEURS
La présente invention a pour objet des perfectionnements auxrécipients ou cocottes, connues sous le nom d'autocuiseurs dans lesquels la cuisson s'effectue sous-pression.CLOSING AND SECURITY DEVICE FOR ALL CONTAINERS
FOR PRESSURE COOKING, SAID COOKERS
The present invention relates to improvements to receptacles or casseroles, known as pressure cookers in which cooking is carried out under pressure.
1) Au brevet principal, on a décrit un dispositif dans lequel la retenue du couvercle s'opérait en même temps que l'étanchéité, en fonction de la pression qui s'élève à l'intérieur de l'appareil, en bloquant le joint en néoprène alimentaire, dont les caractéristiques en font la pièce maitresse du système, contre le rebord de la collerette de la cuve conçue et usinée en conséquence. 1) In the main patent, a device has been described in which the retention of the cover takes place at the same time as the sealing, as a function of the pressure which rises inside the device, by blocking the seal made of food neoprene, whose characteristics make it the centerpiece of the system, against the rim of the flange of the tank designed and machined accordingly.
L'expérience et les essais en laboratoire ont démontré qu'un risque de fluage du joint, en position permanente de cisaillement sous l'effet d'une très forte pression, pourrait effectivement se produire au cours de manipulations intempestives contre indiquées dans l'utilisation de ce matériel. Experience and laboratory tests have shown that a risk of creep of the joint, in a permanent shear position under the effect of very high pressure, could actually occur during untimely handling, contraindicated in use. of this material.
Pour pallier à ce risque, la présente addition montre une nouvelle forme de réalisation de l'invention parfaitement sécurisante. To overcome this risk, the present addition shows a new embodiment of the invention which is perfectly secure.
Il s'agit de l'adjonction sur la cuve d'une couronne formant étrier annulaire amovible, munie de poignées de manoeuvre, coiffant intégralement le tore du joint lorsque la pression de fonctionnement de l'appareil est atteinte. Eludant ainsi tout risque de fluage entre le haut de la génératrice du couvercle et le rebord de la couronne-étrier en raison de l'infime espace qui subsiste entre les deux éléments en plein fonctionnement. It is the addition to the tank of a crown forming a removable annular stirrup, provided with operating handles, fully covering the torus of the joint when the operating pressure of the device is reached. Eluding any risk of creep between the top of the generator of the cover and the rim of the caliper ring due to the tiny space that remains between the two elements in full operation.
On peut atteindre ainsi aisément et sans risque des pressions permettant à l'appareil ainsi conçu des températures propres à la stérilisation ou la conserverie. Pressures can thus be reached easily and safely allowing the device thus designed temperatures suitable for sterilization or canning.
2) Les autres éléments de régulation et de fonctionnement du brevet principal restant indentiques, avec les encoches de sécurité pratiquées cette fois sur la couronne-étrier permettant la déformation du joint, et le pointeau régulateur statique, muni de son déflecteur, qui détermine la température de cuisson. 2) The other regulatory and operating elements of the main patent remain identical, with the safety notches made this time on the stirrup ring allowing the deformation of the seal, and the static regulating needle, fitted with its deflector, which determines the temperature Cooking.
Au dessous du couvercle, on disposera de la crépine anti-bouchage habituelle. Below the lid, there will be the usual anti-clogging strainer.
Le positionnement du couvercle s'effectuera de façon identique au brevet principal, et la mise en place de la couronne-étrier se fera à l'aide d'une rampe de baionnettes d'un système courant. The positioning of the cover will be carried out in the same way as the main patent, and the installation of the stirrup crown will be done using a ramp of bayonets of a current system.
Par contre, le joint ne comportera plu3d'extension de préhension, celleci n'étant plus nécessaire à sa pose ou sa dépose une fois la couronne-étrier enlevée. On the other hand, the joint will no longer have a gripping extension, this being no longer necessary for its installation or its removal once the crown-caliper has been removed.
Au dessin
La Figure I représente le plan de la couronne-étrier (20) vue du dessus comportant 2 encoches (3) et les 4 baïonnettes internes (21) de liaison avec la cuve. Les deux poignées (6) de manoeuvre permettant la pose et le dépose de cette couronne-étrier sur la cuve-récipient (1).In the drawing
Figure I shows the plan of the caliper ring (20) seen from above comprising 2 notches (3) and the 4 internal bayonets (21) for connection with the tank. The two maneuvering handles (6) allowing the fitting and removal of this stirrup ring on the vessel-container (1).
La Figure II représente les baionnettes saillantes (21) venues de fonderie sur le haut du corps de la cuve (1). Figure II shows the protruding bayonets (21) from the foundry on the upper body of the tank (1).
La Figure III représente une coupe de l'assemblage de la couronne-étrier (20) sur la cuve (1) au moyen des baionnettes (21). Le couvercle (2) reposant sur son repos avec le joint (17) mis en place prêt à fonctionner. En pointillé est figuré la coupe de l'appareil en pression avec le couvercle comprimant le joint et ne laissant qu'un infime passage entre couronne-étrier et couvercle et interdisant ainsi tout fluage du joint. Figure III shows a section of the assembly of the caliper ring (20) on the tank (1) by means of the bayonets (21). The cover (2) resting on its rest with the seal (17) in place ready to operate. In dotted line is shown the section of the device under pressure with the cover compressing the seal and leaving only a tiny passage between crown-caliper and cover and thus preventing any creep of the seal.
La figure IV représente l'appareil en état de fonctionnement, avant mise en pression. La coupe fait apparaître la couronne-étrier (20) munie de ses poignées (6) et engagée dans les baionnettes (21) de la cuve (1). Figure IV shows the device in working condition, before pressurization. The cut reveals the crown-stirrup (20) provided with its handles (6) and engaged in the bayonets (21) of the tank (1).
Le couvercle (2) sur son repos, avec le joint (17) muni de deux boutons de préhension comme sur le brevet principal, avec son pointeau statique de fonctionnement (13-15) équipé d'un déflecteur (14) et d'une crépine haute (9) sur laquelle est fixée la crépine inférieure anti-bouchage (11) retenue par un bouton moleté (12) sur le manchon-siège (10) qui complète le système de fonctionnement comme il est dit au brevet principal. The cover (2) on its rest, with the seal (17) provided with two gripping buttons as on the main patent, with its static operating needle (13-15) equipped with a deflector (14) and a high strainer (9) on which is fixed the lower anti-clogging strainer (11) retained by a knurled button (12) on the seat sleeve (10) which completes the operating system as described in the main patent.
La figure V représente la coupe de l'appareil en fonctionnement : le couvercle (2) poussé par la pression interne qui s' exerce dans la cuve (1) plaque le joint (17) contre la couronne-étrier et le comprime en créant une étanchéité parfaite en ne lui laissant aucune possibilité de fluer car aucun espace ne subsiste entre le corps de la cuve et la couronne-étrier en fonctionnement. Figure V shows the section of the device in operation: the cover (2) pushed by the internal pressure which is exerted in the tank (1) presses the seal (17) against the caliper crown and compresses it by creating a perfect tightness by leaving it no possibility of creeping because no space remains between the body of the tank and the crown-caliper in operation.
