Description

Réservoir pour gaz sous pressionReservoir for pressurized gas

L’invention concerne un réservoir pour gaz sous pression, tel de l’hydrogène, du GNV ou du GNC.The invention relates to a tank for gas under pressure, such as hydrogen, CNG or CNG.

Un tel réservoir comprend, selon un mode de réalisation classique, une structure pouvant être réalisée en composite par enroulement filamentaire autour d’un axe. Aussi la structure, et donc le réservoir, présente une forme de révolution autour dudit axe, cette forme étant le plus souvent cylindrique, terminée à chacune de ses deux extrémités par une calotte hémisphérique. La structure comprend au moins une ouverture, avantageusement sur l’axe, au centre d’une calotte hémisphérique, accueillant une embase.Such a tank comprises, according to a conventional embodiment, a structure that can be made of composite by filament winding around an axis. Also the structure, and therefore the tank, has a shape of revolution around said axis, this shape being most often cylindrical, terminated at each of its two ends by a hemispherical cap. The structure comprises at least one opening, advantageously on the axis, in the center of a hemispherical cap, accommodating a base.

L’embase, classiquement métallique est traversante relativement à la structure et comprend un perçage fileté apte à accueillir un accessoire, typiquement une vanne de remplissage/puisage et ses sécurités.The base, conventionally metallic, passes through the structure and includes a threaded hole suitable for accommodating an accessory, typically a filling/drawing valve and its safety devices.

Le réservoir comprend encore une enveloppe (ou « liner »), recouvrant toute la surface interne de la structure, assurant une étanchéité au gaz. Cette enveloppe est interfacée de manière étanche avec l’embase.The reservoir further comprises an envelope (or "liner"), covering the entire internal surface of the structure, ensuring gas tightness. This casing is interfaced in a leaktight manner with the base.

Dans les réservoirs de l’art antérieur, l’embase déborde nettement du profil de la structure. Ce débordement est problématique en ce qu’il peut gêner ou empêcher le passage d’un outil réalisant l’enroulement filamentaire, principalement à proximité de l’ouverture.In the tanks of the prior art, the base clearly overflows the profile of the structure. This overflow is problematic in that it can hinder or prevent the passage of a tool carrying out the filament winding, mainly near the opening.

Ce débordement de l’embase hors du profil de la structure permet encore, typiquement par serrage de la partie débordante de maintenir l’embase en rotation, pour que, le vissage de l’accessoire dans le perçage fileté de l’embase n’occasionne pas de couple ente l’embase et la structure, un tel couple risquant d’endommager l’interface entre l’enveloppe et l’embase.This overflow of the base out of the profile of the structure still allows, typically by tightening the overhanging part, to maintain the base in rotation, so that the screwing of the accessory in the threaded hole of the base does not cause no torque between the base and the structure, such a torque risking damaging the interface between the casing and the base.

Aussi, il est recherché un réservoir ne présentant sensiblement pas d’excroissance hors du profil du réservoir pendant la réalisation de la structure par enroulement filamentaire et permettant d’immobiliser l’embase en rotation durant l’étape ultérieure de vissage de l’accessoire.Also, a reservoir is sought that does not have substantially any protrusion outside the profile of the reservoir during the construction of the structure by filament winding and that makes it possible to immobilize the base in rotation during the subsequent step of screwing the accessory.

Une idée de l’invention est de réaliser une embase « raccourcie » de manière à ne pas déborder du profil du réservoir. Cependant, une telle embase raccourcie ne permet plus un serrage par un outil de maintien empêchant la rotation de l’embase pendant le vissage de l’accessoire.One idea of the invention is to make a "shortened" base so as not to overflow the profile of the tank. However, such a shortened base no longer allows tightening by a holding tool preventing the rotation of the base during the screwing of the accessory.

Aussi, l’invention propose un réservoir pour gaz sous pression, comprenant une structure et une embase, la structure étant sensiblement de révolution autour d’un premier axe, comprenant selon le premier axe une ouverture accueillant l’embase, l’embase étant sensiblement de révolution autour du premier axe, traversante et comprenant un perçage fileté apte à accueillir un accessoire, où l’embase est conformée pour être sensiblement inscrite dans le profil de la structure et comprend un premier dispositif anti-rotation autour du premier axe et le réservoir comprend encore une douille, sensiblement de révolution autour d’un deuxième axe, comprenant un deuxième dispositif anti-rotation apte à s’embrayer avec le premier dispositif anti-rotation, de manière à empêcher une rotation de l’embase relativement à la douille autour du premier axe et du deuxième axe alignés.Also, the invention proposes a tank for pressurized gas, comprising a structure and a base, the structure being substantially of revolution around a first axis, comprising along the first axis an opening receiving the base, the base being substantially of revolution around the first axis, traversing and comprising a threaded hole capable of receiving an accessory, where the base is shaped to be substantially inscribed in the profile of the structure and comprises a first anti-rotation device around the first axis and the reservoir further comprises a sleeve, substantially of revolution around a second axis, comprising a second anti-rotation device adapted to engage with the first anti-rotation device, so as to prevent rotation of the base relative to the sleeve around of the first axis and the second axis aligned.
