Abstract

Arrêt automatique du passage d'un liquide dans une chambre en présence de gaz. Le liquide arrive par 2 dans la chambre 1 et sort de celle-ci par 3. S'il renferme des bulles gazeuses, ces dernières s'accumulent dans la partie haute lc en provoquant la descente du flotteur 4, lequel vient finalement porter de façon étanche contre la paroi de la partie inférieure tronconique 1b de la chambre en formant clapet d'obturation. Application aux appareils médicaux dans lesquels on fait circuler du sang ou solution aqueuse injecté ou ré-injecté dans le sujet.
