Title (EN) GAS GENERATOR
(FR) GÉNÉRATEUR DE GAZ
(JA) ガス発生器
Abstract:
(EN) This gas generator has a plurality of gas ejection holes that are arranged along a circumferential direction in a peripheral wall section (22) so as not to overlap with each other, wherein the plurality of gas ejection holes consist of first to third gas ejection hole groups, each comprising one or more gas ejection hole sets. The gas ejection holes belonging to each of the first to third gas ejection hole groups have the same release pressure; the gas ejection holes (23b) belonging to the second gas ejection hole group each have a release pressure higher than that of the gas ejection holes (23a) belonging to the first gas ejection hole group, whereas the gas ejection holes (23c) belonging to the third gas ejection hole group each have a release pressure higher than that of the gas ejection holes (23b) belonging to the second gas ejection hole group. Every set of the gas ejection holes belonging to the respective gas ejection hole groups is arranged evenly so as to be rotationally symmetrical with an angle of not more than 120°.
(FR) Générateur de gaz comportant une pluralité de trous d'éjection de gaz qui sont agencés le long d'une direction circonférentielle dans une section paroi périphérique (22) de manière à ne pas se chevaucher, la pluralité de trous d'éjection de gaz étant constitués de premier à troisième groupes de trous d'éjection de gaz, comprenant chacun un ou plusieurs ensembles de trous d'éjection de gaz. Les trous d'éjection de gaz appartenant à chacun des premier à troisième groupes de trous d'éjection de gaz ont la même pression de libération; les trous d'éjection de gaz (23b) appartenant au deuxième groupe de trous d'éjection de gaz ont chacun une pression de libération supérieure à celle des trous d'éjection de gaz (23a) appartenant au premier groupe de trous d'éjection de gaz, alors que les trous d'éjection de gaz (23c) appartenant au troisième groupe de trous d'éjection de gaz ont chacun une pression de libération supérieure à celle des trous d'éjection de gaz (23b) appartenant au deuxième groupe de trous d'éjection de gaz. Tous les ensembles des trous d'éjection de gaz appartenant aux groupes de trous d'éjection de gaz respectifs sont agencés de façon régulière de manière à être symétriques en rotation selon un angle de pas plus 120 °.
(JA) ガス発生器は、周壁部(22)に周方向に沿って互いに重ならないように配置された複数個のガス噴出口を有し、複数個のガス噴出口は、それぞれが1組または2組以上からなる第1ないし第3ガス噴出口群のみにて構成される。第1ないし第3ガス噴出口群の各々に含まれるガス噴出口同士は、互いに同一の開放圧を有し、第2ガス噴出口群に含まれるガス噴出口(23b)は、第1ガス噴出口群に含まれるガス噴出口(23a)よりも開放圧が高く、第3ガス噴出口群に含まれるガス噴出口(23c)は、第2ガス噴出口群に含まれるガス噴出口(23b)よりも開放圧が高い。1組のガス噴出口群の各々に含まれるガス噴出口は、いずれも120°以下の角度をもって回転対称性を有するように均等に配置される。
