Abstract

AMORTIGUADOR DE VIBRACIONES CON FUERZA DE AMORTIGUACION AJUSTABLE, ABARCANDO UN TUBO A PRESION RELLENO DEL MEDIO AMORTIGUADOR, EN DONDE UN EMBOLO CON UN VASTAGO (3) DE EMBOLO MOVIBLE AXIALMENTE DISPONE DE UN ESPACIO DE TRABAJO SUBDIVIDIDO EN UNA ZONA ALEJADA DEL VASTAGO Y UNA ZONA AL LADO DEL VASTAGO. SE DISPONE DE UNA CORRIENTE DEL AGENTE AMORTIGUADOR ENTRE AMBOS ESPACIOS (33,35) DE TRABAJO, DIVIDIDOS EN UNA CORRIENTE PRINCIPAL Y UNA CORRIENTE PROXIMA. ESTA COMPUESTO EL EQUIPO (1) DE VALVULA DE AMORTIGUACION DE UN CUERPO DE VALVULA, CON UNA VALVULA DE ETAPAS PRINCIPAL PARA CADA DIRECCION DE CORRIENTE, QUE ESTA CONFIGURADA A TRAVES DE LOS RESPECTIVOS CUERPOS (21A, 21B) DE VALVULA DE ETAPAS PRINCIPAL, Y UNA VALVULA DE ETAPAS PREVIA, QUE CONTROLA LA VALVULA DE ETAPAS PRINCIPAL, UN ACTUADOR REGULABLE, QUE INFLUYE UNA UNION DE CORRIENTE ENTRE UN ESPACIO (19) DE CONTROL Y UN ESPACIO (33,35) DE TRABAJO. EL ESPACIO (19) DE CONTROL ESTA LIMITADO AXIALMENTE A PARTIR DEL PRIMER Y EL SEGUNDO CUERPO (21A, 21B) DE VALVULA DE ETAPAS PRINCIPAL IMPULSADOS MEDIANTE FUERZA ELASTICA. EL PRIMER CUERPO DE ETAPAS DE VALVULA PRINCIPAL SE MUEVE EN LA AFLUENCIA A PARTIR DEL AJUSTE DE VALVULA CERRADO EN UNA POSICION DE ABERTURA EN EL ESPACIO (19) DE CONTROL SOBRE EL SEGUNDO CUERPO DE VALVULA DE ETAPAS PRINCIPAL, QUE ESTA MANTENIDO A PARTIR DEL MEDIO DE AMORTIGUACION EN EL AJUSTE DE VALVULA CERRADO Y MEDIANTE DIRECCION DE CORRIENTE DE INVERSION DEL SEGUNDO CUERPO DE VALVULA DE ETAPAS PRINCIPAL SE MUEVE A PARTIR DE UN AJUSTE DE VALVULA CERRADO EN UNA POSICION DE ABERTURA EN DIRECCION AXIAL QUE SE ENCUENTRA EN LA REGULACION DE VALVULA CERRADA DEL PRIMER CUERPO DE ETAPAS PRINCIPAL.
