Abstract

Amortiguador oscilante, que comprende: - una carcasa (12) que define una cámara (14) llena de un fluido amortiguador magneto-reológico o electro-reológico; - una placa oscilante (22), que puede moverse en el interior de dicha cámara (14) y está dispuesta de tal forma que divide la cámara (14) en dos partes de volumen variable (24, 26); y - por lo menos un orificio de paso (28) creado en la placa oscilante (22) para permitir que el fluido pase de una a otra parte cuando dicha placa (22) se mueve; caracterizado porque se proporciona un dispositivo excitador (30) eléctricamente controlada en correspondencia con dicho orificio de paso (28) para controlar la resistencia efluente del fluido que circula a través de dicho orificio de paso (28).
