Abstract

L'invention concerne un appareil de réduction active des vibrations verticales d'une masse Elle se rapporte à un appareil qui comprend, entre la masse vibrante 1 et un organe élastique de base 21, un transformateur 2 d'accélération qui commande, par l'intermédiaire d'un amplificateur 3, l'ouverture et la fermeturc de soupapes 14, 15 permettant le passage d'air comprimé vers l'ensemble élastique 5 ou à partir de celui-ci, dans un sens qui réduit les vibrations. Application à la suspension de parties de véhicules ou de sièges.
