Abstract

L'invention concerne une vanne de régulation de fluide possédant une structure équilibrée. Ladite vanne requiert peu de force pour être activée, elle comprend un logement pourvu d'un orifice d'alimentation et d'un orifice de sortie, un siège situé à l'intérieur du boîtier entre les orifices, et une tige creuse dotée d'une extrémité située à l'intérieur du logement et qui fait face au siège et est adjacente à ce dernier, et une extrémité opposée faisant face à l'un des orifices avec lequel elle est alignée. La tige creuse et le siège sont supportés l'un par rapport à l'autre à l'intérieur du logement de telle façon qu'ils soient mobiles l'un par rapport à l'autre : a) afin de provoquer l'espacement entre l'une des extrémités de la tige creuse et le siège, et ainsi ouvrir la vanne au flux de fluide à travers la tige creuse, de l'orifice d'alimentation à l'orifice de sortie ; ou b) afin d'amener une extrémité de la tige creuse en contact ferme avec le siège et ainsi fermer la vanne au flux de liquide, de l'orifice d'alimentation à l'orifice de sortie.
