Abstract

La présente invention est du domaine des techniques de la régulation et elle a pour objet une vanne hygrostatique destinée à l'horticulture. Une vanne hygrostatique ou humidostat selon l'invention est principalement caractérisée par un organe de compression 5 en forme de doigt sollicité en déplacement de façon antagoniste par un ressort 7 d'une part et par un élément hygrosensible 8 d'autre part; le ressort tendant à provoquer un deplacement du doigt 5 produisant un effet de compression et d'obturation d'une partie souple 6 d'un conduit, l'élément hygrosensible tendant à produire l'effet inverse; une ossature 1 permet l'assemblage des différents éléments constitutifs de la vanne et lui donne sa forme générale allongée. Application à la culture des plantes en pot et en pleine terre.
