Abstract

Valve d'expiration. Elle comprend un logement de valve possédant une entrée pour la liaison avec la sortie d'expiration d'un appareil de ventilation et une sortie, un siège de valve disposé à l'intérieur du logement, un disque de valve rappelé dans une direction amont pour engager ledit siège de valve et une chambre d'amortissement contenant un fluide visqueux et agencée de façon que le mouvement du disque de valve à l'intérieur du logement provoque le mouvement du fluide visqueux à l'intérieur de la chambre d'amortissement, ce qui a pour effet d'amortir les vibrations. Application aux appareils respiratoires.
