Abstract
Hybrid-Gasgenerator mit einem Anzündelement (23), einer aus einem reaktiven Flüssiggas (11) bestehenden anzündbaren gaserzeugenden Ladung, die in einem durch ein erstes Schließelement (12) verschlossenen Behälter (10) enthalten ist, und einer ein Druckgas enthaltenden Speicherkammer (13), die durch ein weiteres Schließelement (17) verschlossen ist, und einem von dem Anzündelement (23) angetriebenen Masseteil (25) zum Zerstören des ersten Schließelements (12) zur Ermöglichung des Austritts des Flüssiggases (11) aus dem Behälter (10), dadurch gekennzeichnet, dass die Schließelemente (17, 12) von Speicherkammer (13) und Behälter (10) in Bewegungsrichtung des Masseteils (25) hintereinander angeordnet sind und von dem Masseteil (25) nacheinander durchdrungen werden.Hybrid gas generator with a lighting element (23), one of a reactive liquid gas (11) existing flammable gas generating charge, which in a through a first closing element (12) sealed container (10), and a storage chamber containing a compressed gas (13) closed by a further closing element (17) is, and one of the ignition element (23) driven mass part (25) for destroying the first closing element (12) to enable the exit of the liquefied gas (11) from the container (10), characterized in that the closing elements (17, 12) of storage chamber (13) and containers (10) in the direction of movement of the mass part (25) arranged one behind the other are and are penetrated by the mass portion (25) successively.
Description
Die Erfindung betrifft einen Hybrid-Gasgenerator nach dem Oberbegriff des einigen Anspruches.The The invention relates to a hybrid gas generator according to the preamble of some claim.
Aus
Ein
Hybrid-Gasgenerator, von dem der Oberbegriff des Patentanspruchs
1 ausgeht, ist beschrieben in
Der Erfindung liegt die Aufgabe zugrunde, einen Hybrid-Gasgenerator mit verbessertem Auslöseverhalten zu schaffen.Of the Invention is based on the object, a hybrid gas generator with improved triggering behavior to accomplish.
Der erfindungsgemäße Hybrid-Gasgenerator ist durch den Patentanspruch 1 definiert. Er ist dadurch gekennzeichnet, dass die Schließelemente von Speicherkammer und Behälter in Bewegungsrichtung des Masseteils hintereinander angeordnet sind und von dem Masseteil nacheinander durchdrungen werden.Of the inventive hybrid gas generator is defined by the patent claim 1. He is characterized that the closing elements of Storage chamber and container are arranged one behind the other in the direction of movement of the mass part and be penetrated by the mass part successively.
Erfindungsgemäß durchschlägt das Masseteil die beiden hintereinander angeordneten Schließelemente, so dass diese von demselben Masseteil nacheinander geöffnet werden.According to the invention, the mass fraction penetrates the two successively arranged closing elements, so that these from the same mass part are opened in succession.
Ein Vorteil besteht darin, dass der Behälter und die Speicherkammer von dem Masseteil nahezu zeitgleich bzw. mit geringer Verzögerung, zur Mischkammer hin geöffnet werden, und dass nicht erst nach dem Öffnen des ersten Schließelements ein Druck aufgebaut werden muss, der dann das zweite Schließelement öffnet.One Advantage is that the container and the storage chamber from the mass part almost at the same time or with a slight delay, opened to the mixing chamber be, and that not only after opening the first closing element a pressure must be built, which then opens the second closing element.
Im folgenden wird unter Bezugnahme auf die Zeichnungen ein Ausführungsbeispiel der Erfindung näher erläutert.in the The following will be an embodiment with reference to the drawings closer to the invention explained.
