Abstract

Amortiguador de vibraciones (1) con fuerza de amortiguación ajustable, que comprende un cilindro (7) en el que va guiado con movilidad axial un pistón (5) con un vástago de pistón (3), subdividiendo el pistón al cilindro en una primera y una segunda cámaras de trabajo (9; 11), y al menos una válvula de amortiguación (39; 41; 43) cuyas válvulas individuales (39; 41; 43) están dispuestas en un bloque de válvulas (21) en unión de flujo entre las dos cámaras de trabajo y pueden ser influenciadas en su característica de la fuerza de amortiguación a través de medios de ajuste exteriores (51; 55; 37), estando unido el bloque de válvulas (21) con el cilindro (7) a través de al menos una unión de flujo (19) y estando dividido en dos partes un tubo recipiente (13, 13a) que envuelve al cilindro (7) y que se extiende, respectivamente, por encima y por debajo del bloque de válvulas (21), caracterizado porque una tapa (25) está unida con el cilindro (7) en el lado de salida del vástago de pistón y una unión roscada (27) en la tapa (25) y/o una unión roscada (27a) entre el cilindro (7) y la parte inferior (13a) del recipiente proporcionan una serie de afianzamientos entre la tapa (25), la parte superior (13) del tubo recipiente, el bloque de válvulas (21) y la parte inferior (13a) del tubo recipiente, de modo que el bloque de válvulas (21) puede ser girado hasta cualquier posición antes del atornillamiento definitivo de la unión o uniones roscadas.
