Abstract

L'invention concerne des contenants frigorifiques présentant un casier destiné à recevoir des produits à réfrigérer ainsi qu'un compartiment à réfrigérant distinct du casier. Pour le remplissage des contenants frigorifiques, on utilise des dispositifs de remplissage, avec lesquels du dioxyde de carbone liquide est injecté à l'état liquéfié dans le compartiment à réfrigérant où il est transformé en partie en dioxyde de carbone gazeux et en partie en dioxyde de carbone solide. Les pistolets de remplissage, utilisés à cet effet, comprennent non seulement une buse de détente mais aussi des moyens d'évacuation du dioxyde de carbone gazeux, des moyens de raccordement électrique et des détecteurs ainsi qu'au moins une soupape de commande destinée à la commande de l'alimentation en dioxyde de carbone liquide. Ces pistolets de remplissage s'avèrent donc très onéreux en termes de construction et, en raison de leur poids propre élevé, leur utilisation implique d'avoir recours à un support par l'intermédiaire d'un système à palan. Selon l'invention, un dispositif de remplissage comprend un pistolet de remplissage, présentant seulement une buse de détente pour l'alimentation en dioxyde de carbone liquide, un orifice de décharge pour l'évacuation du dioxyde de carbone gazeux et éventuellement des éléments détecteurs non électriques. La totalité des soupapes et des composants électriques destinés à la commande du remplissage est affectée à un des pistolets de remplissage et est intégrée à ce dernier par une unité d'alimentation raccordée par des tuyaux flexibles. Le pistolet de remplissage selon l'invention est très léger et peut être utilisé sans nécessiter d'avoir recours à des moyens de retenue mécaniques.
