Abstract

LA INVENCION SE REFIERE A UN AMORTIGUADOR DE OSCILACION CON FUERZA DE AMORTIGUACION AJUSTABLE, ABARCANDO UN CILINDRO EN EL QUE SE GUIA CON MOVIMIENTO AXIAL UN EMBOLO CON UN VASTAGO DE EMBOLO. EL EMBOLO SUBDIVIDE EL CILINDRO EN UN PRIMER Y EN SEGUNDO ESPACIO DE TRABAJO, CON AL MENOS UNA VALVULA DE AMORTIGUACION, QUE ESTA DISPUESTA EN UNA UNION DE CORRIENTE ENTRE AMBOS ESPACIOS DE TRABAJO Y ES INFLUENCIABLE A TRAVES DEL MEDIO DE AJUSTE, QUE SE APLICA SEGUN LA LINEA CARACTERISTICA DE LA FUERZA DE AMORTIGUACION, DE FORMA QUE LA VALVULA DE AMORTIGUACION SE COMPONE DE VALVULAS INDIVIDUALES, CUYOS EFECTOS SE SOLAPAN DE TAL MODO, QUE UNA PRIMERA VALVULA INDIVIDUAL SE COMPONE DE UN ESTRANGULADOR DE SECCION TRANSVERSAL REDUCIDA Y UNA SEGUNDA VALVULA INDIVIDUAL ABARCA AL MENOS UN DISCO DE VALVULA QUE SE ENCUENTRA BAJO CARGA ELASTICA Y DONDE LA PRIMERA Y LA SEGUNDA VALVULA INDIVIDUALES SON AJUSTABLE INDIVIDUALMENTE A TRAVES DEL MEDIO DE AJUSTE EN SU EFECTO. LAS VALVULAS INDIVIDUALES ESTAN DISPUESTAS PARA AL MENOS UNA DIRECCION DE CORRIENTE DE PASO DE UN BLOQUE DE VALVULAS, QUE SE ENCUENTRA EN UNION A TRAVES DE AL MENOS UNA UNION DE FLUIDO CON EL CILINDRO, DONDE EL TUBO DE RECIPIENTE ESTA EJECUTADO EN DOS RAMALES Y EXTENDIENDOSE DE FORMA RESPECTIVA DENTRO Y FUERA DEL BLOQUE DE VALVULAS.
