Abstract

Dans un système de buse d'amortissement destiné à un fluide hydraulique sous pression, un corps de buse est disposé dans un canal à fluide sous pression. Ce corps de buse comprend un alésage axial partant d'un côté frontal, cet alésage ne traversant pas complètement le corps de buse. Le corps de buse comprend également un alésage radial qui relie l'alésage axial à un espace annulaire formé entre le corps de buse et le canal à fluide sous pression. Entre cet espace annulaire et le canal à fluide sous pression sont disposées deux buses de section rectangulaire qui déterminent l'effet d'étranglement du système de buse d'amortissement. L'invention concerne un système de buse d'amortissement qui peut être produit facilement même si l'effet d'étranglement recherché est important. A la place des deux buses de section rectangulaire, on utilise pour le diamètre extérieur du corps de buse et pour le diamètre intérieur du canal à fluide sous pression qui l'entoure des dimensions telles qu'un interstice annulaire délimité dans le sens axial soit formé entre le corps de buse et le canal à fluide sous pression, le corps de buse étant fermement maintenu dans le canal à fluide sous pression. Ce type de système de buse est employé pour amortir des systèmes hydrauliques enclins aux vibrations.
