Abstract

Le dispositif qui sert à stériliser les liquides à l'aide de lumière ultraviolette, comprend un cadre (1) dans lequel on place une conduite d'admission (2) du liquide et une conduite d'émission (3) du liquide ainsi qu'une lampe à lumière ultraviolette (4). Les dispositifs similaires actuels sont compliqués et difficiles à réparer. Dans le dispositif décrit de la présente invention, des espaces pour la circulation (5) sont ménagés dans le cadre à l'endroit de la conduite d'admission et de la conduite d'émission, le diamètre desdits espaces étant supérieur au diamètre du centre (6) du cadre qui est situé entre eux.
