Abrégé
(EN)
A pressure relief valve (14, 14A) has a reciprocable valve member (34, 34A) for seating on an annular seat face (66, 66A) of a nozzle assembly (38, 38A). The nozzle assembly (38, 38A) has an inner seat ring (40, 40A), a radially outer anchor ring (42, 42A), and a flexible connecting member (44, 44A) extending in a generally radial direction between the outer peripheral surface (64) of the seat ring (40, 40A) and the inner peripheral surface of the anchor ring (42, 42A). Upon seating or reseating of the valve member (34, 34A), seal face (36, 36A) contacts the seat face (66, 66A) of seat ring (40, 40A) and flexible connecting member (44, 44A) flexes upon relative movement of the seat ring (40, 40A) after initial contact of the valve member (34, 34A) against the seat ring (40, 40A) thereby to act as a shock absorber for absorbing impact forces.
(FR)
L'invention se rapporte à une soupape de surpression (14, 14A), qui comprend un élément de soupape à mouvement alternatif (34, 34A) venant se fermer sur une face de siège annulaire (66, 66A) d'un ensemble à ajutage (38, 38A). L'ensemble à ajutage (38, 38A) comporte un anneau de siège interne (40, 40A), un anneau d'ancrage radialement externe (42, 42A), et un raccord flexible (44, 44A) s'étendant dans une direction généralement radiale entre la surface périphérique externe (64) de l'anneau de siège (40, 40A) et la surface périphérique interne de l'anneau d'ancrage (42, 42A). Lors de la fermeture ou de la refermeture de l'élément de soupape (34, 34A), la face d'étanchéité (36, 36A) entre en contact avec la face de siège (66, 66A) de l'anneau de siège (40, 40A) et le raccord flexible (44, 44A) subit une flexion sous l'effet du mouvement relatif de l'anneau de siège (40, 40A), après contact initial de l'élément de soupape (34, 34A) contre l'anneau de siège (40, 40A), de façon à servir d'amortisseur absorbant les forces de choc.
