Abstract

AMORTIGUADOR, PARA COMPENSACION DECARGA, PARA SUSPENSION DE VEHICULO AUTOMOVIL DEL TIPO QUE COMPORTA UN CILINDRO (2) QUE CONTIENE UN LIQUIDO HIDRAULICO, UN PISTON (1) ACCIONADO POR BARRA (3), DEFINIENDO EN EL CILINDRO UNA PRIMERA CAMARA (2A) Y UNA SEGUNDA CAMARA (2B). ESTA SEGUNDA CAMARA CONTIENE LA BARRA, UN DEPOSITO DE LIQUIDO HIDRAULICO (11) QUE PUEDE COMUNICARSE CON LA PRIMERA CAMARA (2A) POR MEDIO DE UNA RESTRICCION (23) EN EL MOMENTO DE UN MOVIMIENTO DE COMPRESION RAPIDA. UNA VALVULA DE MANDO (30) ES CAPAZ DE ABRIR UN PASO DE LIQUIDO ENTRE LA PRIMERA (2A) Y LA SEGUNDA CAMARA (2B), DICHA VALVULA DE MANDO (30) ESTA SOMETIDA, DE UNA PARTE, A LA PRESION DEL LIQUIDO HIDRAULICO QUE SE ENCUENTRA EN LA PRIMERA CAMARA (2A) TENDIENDO A ABRIR LA VALVULA, Y DE OTRA PARTE A LA ACCION, TENDIENDO A CERRAR LA VALVULA, DE UN RESORTE DE LLAMADA (35) Y DE LA PRESION SENSIBLEMENTE CONSTANTE DE UN FLUIDO CONTENIDO EN UNA CAMARA DE REFERENCIA (28) EN LA CUAL UNA PARED ES MOVIL CON LA VALVULA DE MANDO. UNA ENVUELTA EXTERNA DE COMPENSACION (46) ESTA UNA A LA BARRA (3) Y ENCIERRA EL AMORTIGUADOR; DICHA ENVUELTA DE COMPENSACION ESTA LIGADA POR UN CONDUCTO (52,44,51) A UNA FUENTE DE PRESION VARIABLE EXTERIOR.
