Abstract

UNA VALVULA (1) DE REGULACION DE NIVEL PARA MANTENIMIENTO CONSTANTE AUTOMATICO DE LA ALTURA DE VEHICULO DE UN VEHICULO INDUSTRIAL CON SUSPENSION NEUMATICA ESTA PROVISTA CON UN CUERPO (17) DE VALVULA DOBLE CARGADA ELASTICAMENTE, CON UN ASIENTO DE ENTRADA Y UN ASIENTO (19) DE SALIDA PARA EL EMPUJADOR (20) DE VALVULA O HUECO QUE PORTA EL CUERPO (17) DE VALVULA DOBLE Y ES DESPLAZABLE DE MANERA ESTANCA. LA POSICION DEL EMPUJADOR (20) DE VALVULA ES RELATIVA CON RESPECTO A LA CARCASA (2) DE LA VALVULA (1) DE REGULACION DE NIVEL A TRAVES DE UN ACCIONAMIENTO (6) DE AJUSTE QUE DISTANCIA LA ALTURA DE VEHICULO CON UNA PIEZA (27) DE GUIA Y LEVAS (10) DE EXCENTRICA DE FORMA MODIFICABLE. A TRAVES DEL ACCIONAMIENTO (6) DE AJUSTE ES CONTROLABLE DE FORMA CORRESPONDIENTE UNA POSICION DE CIERRE EN UNA PRIMERA ALTURA DEL VEHICULO. LA VALVULA (1) DE REGULACION DE NIVEL MUESTRA ADEMAS UN EMBOLO (28) DE CONTROL IMPULSABLE DE FORMA ALINEADA CON EL EMPUJADOR (10) DE VALVULA Y PROVISTO A ELECCION PARA EL CONTROL DE UNA SEGUNDA ALTURA DEL VEHICULO EN UNA CAMARA (31) DE CONTROL. LA CAMARA (31) DE CONTROL ESTA DISPUESTA EN LA PIEZA (27) DE GUIA DEL ACCIONAMIENTO (6) DE AJUSTE. EL EMBOLO (18) DE CONTROL ESTA APOYADO DE FORMA ESTANCA CON LA PIEZA (27) DE GUIA Y DESPLAZABLE DE FORMA LIMITADA, DE TAL MODO QUE MEDIANTE CONTROL TAMBIEN DE LA SEGUNDA ALTURA DE VEHICULO LA LEVA (10) EXCENTRICA DEL ACCIONAMIENTO (6) DE AJUSTE PERMANECE NO CARGADA POR LA FUERZA DE AJUSTE EJERCIDA A TRAVES DEL EMBOLO (28) DE CONTROL. EL EMPUJADOR (20) DE VALVULA ESTA APOYADO EN EL EMBOLO (28) DE CONTROL.
