Title (EN) HYGROSTATIC CONTROL DEVICE
(FR) DISPOSITIF HYGROSTATIQUE DE COMMANDE
Abstract:
(EN) A hygrostatic control device characterized in that, firstly, on said mobile assembly (14), is fixed a second resilient member (15) such as at least one spring, which is less powerful than the first resilient member (12) and which forces at least one element of the mobile assembly (14) in a direction contrary to the action of the first resilient member (12), and secondly in that a means (20, 21) is provided in the device which, in at least one of the characteristic positions of the mobile assembly (14), gives at least priority to the action of only one of the resilient members (12, 15).
(FR) L'invention se rapporte à un dispositif hygrostatique de commande. Il est caractérisé en ce que: d'une part, sur ledit ensemble mobile (14), est intercalé un second organe élastique (15), tel au moins un ressort dont la force est inférieure à celle du premier organe élastique (12) et qui sollicite au moins une pièce de l'ensemble mobile (14) dans une direction opposée à celle où s'exerce l'action du premier organe élastique (12) et, d'autre part, dans le dispositif, on prévoit des moyens (20, 21) qui, dans au moins une position caractéristique de l'ensemble mobile (14), donnent au moins priorité à l'action de l'un seulement des organes élastiques (12, 15).
