Claims (6)

  1. Elément de soupape (3, 6, 10) comprenant un corps, au moins un orifice d'entrée, au moins un orifice de sortie, un passage reliant l'orlflce d'entrée et l'orifice de sortie, au moins un disque de rupture (13, 35, 63) ou équivalent, qui, quand il n'est pas cassé, ferme le passage de l'orifice d'entrée à l'orifice de sortie, et un élément de piston (15, 36, 65) pourvu d'un élément de perçage ou autre pour percer le disque de rupture, caractérisé en ce que la tige de piston (16, 38, 66) de l'élément de piston est montée de manière étanche contre la paroi de l'espace du vérin, en ce que l'élément de piston (15, 36, 65) est pourvu d'un passage (17, 39, 67) pour un agent de pression, ledit passage s'étendant axialement à travers l'élément de piston depuis un premier côté jusqu'à un second côté, lequel passage passant à travers le piston forme une partie du passage de l'agent de pression après que le disque de rupture (13, 35, 63) a été percé, et en ce que section de la tige de piston est Inférieure à la surface du piston.
  2. Elément de soupape selon la revendication 1, caractérisé en ce que l'élément de perçage (14, 37, 64) est pourvu d'au moins une ouverture (18, 40, 68) s'étendant depuis la surface extérieure de l'élément de piston vers le passage (17, 39, 67) passant à travers l'élément de piston.
  3. Elément de soupape selon la revendication 1 ou 2, caractérisé en ce que le dispositif comprend des moyens (105, 106) pour actionner l'élément de piston.
  4. Elément de soupape selon l'une quelconque des revendications 1 - 3, caractérisé en ce que l'élément de soupape comprend en outre des moyens manuels (106) et/ou automatiques (105) pour actionner l'élément de piston,
  5. Elément de soupape selon l'une quelconque des revendications 1 - 4, caractérisé en ce que l'élément de soupape (10) est une soupape de déclenchement pour le déclenchement d'un système d'agent de pression.
  6. Elément de soupape selon l'une quelconque des revendications 1 - 4, caractérisé en ce que l'élément de soupape (3) est la soupape de fermeture d'une seconde source de pression et en ce qu'elle est ouverte par une impulsion de pression reçue depuis une première source de pression.
