Definitions

  • the cam (51) rotates about its axis along with the shaft (52) and rests on the upper surface (48) of the piston (43), being shown in Figure 7 at the obturation position of the first hermetic seal, ie with the registration closed.
  • a plug (112) is coupled coaxially, which at its upper end and surroundings (110) has a complementary conical step ( 113) said frusto-conical portion (110).
  • the outward displacement of the rod (107) by turning on an inner threaded portion of (112) or the same drill (103), determining an endstop for the rod and defining a hermetic seal seat between the rod and the body of the register by complementary seating (110) against (113).

Abstract

L'invention comprend un corps pouvant être accouplé à un contenant, au moins un premier passage faisant communiquer l'intérieur du contenant avec l'extérieur. Dans ledit passage se trouve une tige à déplacement axial dont l'extrémité intérieure fait face à un premier siège définissant un registre. Au niveau de l'extrémité amont, par rapport au premier siège, ledit passage possède un second élément d'obturation, devant lequel, en amont, se trouve un corps d'obturation de géométrie complémentaire, sollicité en permanence dans un sens d'éloignement par un moyen élastique étalonné, la base du corps d'obturation communiquant avec l'entrée dans le corps du registre. Les parties complémentaires dudit corps d'obturation et son siège en position séparée, forment un passage de fluide déterminant un effet Venturi qui définit une dépression capable de surmonter la sollicitation contraire du moyen élastique, de manière que soit formée une valve de sécurité à blocage absolu en cas de débit excessif, disposée à l'intérieur du contenant. La tige possède, en aval du premier siège, une partie tronconique, ledit corps possédant un siège complémentaire qui constitue une butée de fin de course et qui définit un siège à joint étanche entre la tige et le corps du registre, en translation aval. Ladite tige s'étend axialement sur une longueur telle que, lorsqu'elle est en position d'obturation sur le premier siège, elle exerce une sollicitation de poussée sur un moyen d'obturation, de manière que la pression de l'intérieur du récipient soit ajustée sur la pression à l'intérieur du premier passage, en amont du premier siège.
