Abstract

SE ACUERDO CON UN EJEMPLO ILUSTRATIVO DE LA INVENCION SE SUMINISTRA UN AMORTIGUADOR DE OSCILACIONES (10) CON UN BYPASS QUE INTERCONECTA DOS CAMARAS DE FLUIDO (18A, 18B, 20). SE SUMINISTRA UNA VALVULA PRINCIPAL (26) DENTRO DE ESTE BYPASS (24) PARA PERMITIR LA VARIACION DEL COMPORTAMIENTO DE AMORTIGUACION DEL AMORTIGUADOR DE OSCILACION (10). SE UTILIZA UNA VALVULA ELECTROMAGNETICA (22) PARA CONTROLAR LA PRESION HIDRAULICA QUE ACTUA SOBRE LA VALVULA PRINCIPAL. LA VALVULA ELECTROMAGNETICA ES EMPUJADA HACIA UNA POSICION DE EMERGENCIA. LA FUERZA DE DESVIACION PARA ESTE EMPUJE SE OBTIENE MEDIANTE DOS MUELLES QUE ACTUAN EN PARALELO (133A, 133B). EL PRIMERO DE ESTOS MUELLES ES RELATIVAMENTE DEBIL, DE FORMA QUE LA VALVULA PUEDA SER TRANSFERIDA MEDIANTE UNA BAJA CORRIENTE ELECTRICA EN UNA BOBINA MAGNETICA (22) EN CONTRA DE LA ACCION DEL MUELLE DEBIL (133A) HASTA UNA PRIMERA POSICION OPERACIONAL PARA SER USADA DURANTE LA MAYOR PARTE DEL TIEMPO DE FUNCIONAMIENTO DEL AMORTIGUADOR DE OSCILACION (10). MEDIANTE EL INCREMENTO CONSIDERABLE DE LA CORRIENTE ELECTRICA, LA VALVULA (26) PUEDE TRANSFERIRSE ADICIONALMENTE AL INTERIOR DE UNA POSICION DE FUNCIONAMIENTO ADICIONAL QUE SE DESEA SOLAMENTE EN SITUACIONES EXCEPCIONALES. SE NECESITA TAL CONSUMO BAJO DE ENERGIA ELECTRICA PARA EL CONTROL DE LA VALVULA ELECTROMAGNETICA. LA CONDICION DE FUNCIONAMIENTO NORMAL DE LA VALVULA ELECTROMAGNETICA SE ESTABILIZA MEDIANTE UN SEGUNDO MUELLE (133) DE MAYOR DUREZA.
