Abstract

Un mécanisme d'activation de soupape, inversé par la pression d'un fluide de travail (ou un gaz), est présenté. Le mécanisme d'activation de soupape comprend une soupape et un actionneur pneumatique ou hydraulique. Un orifice est défini axialement dans la soupape et l'actionneur qui communique la pression d'un fluide de travail (ou un gaz) agissant sur la face de la soupape sur une chambre d'inversion à l'intérieur du logement de l'actionneur. Le modèle élimine, réduit ou surmonte une force agissant sur une face de la soupape en communiquant une pression de travail commune du fluide (ou du gaz) à un substrat sur l'actionneur avec un vecteur de force résultant opposé à la face de la soupape.
