Abstract: front page image
(EN)According to one aspect of the present invention there is provided a valve assembly (1) which includes: at least one valve port; at least one fluid inlet (3); and an outlet (4) for connection to a fluid system; characterised in that the valve assembly includes a pressure sensitive member (18) which is connected to the outlet, so that the size of the pressure sensitive member is capable of increasing or decreasing in response to pressure changes within the fluid system, wherein the valve is configured so that said increases or decreases to the size of the pressure sensitive member cause the inlet and valve port to move either into or out of alignment with one another.
(FR)Dans un mode de réalisation, cette invention concerne un système de clapet qui comprend au moins un orifice de clapet, au moins une admission de fluide, et une sortie assurant la connexion à un système de fluide. Cette invention se caractérise en ce que le système de clapet comprend un élément sensible à la pression qui est connecté à la sortie, et dont la taille peut augmenter ou diminuer en réponse à des changements de pression dans le système de fluide. Ce clapet est conçu de manière que les augmentations ou les diminutions de la taille de l'élément sensible à la pression entraînent l'alignement ou le désalignement de l'admission et de l'orifice du clapet.
