Abstract

EN UNA CARCASA (10) DEL DISPOSITIVO AMPLIFICADOR SE DISPONE DE DOS CAMARAS (12,14) SEPARADAS POR MEDIO DE UNA PARED (16) MOVIL QUE ESTA CONECTADA AL ALOJAMIENTO (22) DE LA VALVULA. ESTA ULTIMA CONTIENE UN MIEMBRO (60) DE SELLADO MOVIL EN EL QUE ESTA LOCALIZADO UN PRIMER ASIENTO (24) DE VALVULA FORMADO EN EL ALOJAMIENTO (22) DE VALVULA Y UN SEGUNDO ASIENTO DE VALVULA FORMADO SOBRE UN CUERPO (30) DE VALVULA MOVIL. EL CUERPO DE VALVULA SE MUEVE AXIALMENTE SOBRE UN PISTON (42) Y FORMA LA ARMADURA DE UN ELECTROIMAN (40) DISPUESTO DENTRO DEL ALOJAMIENTO DE LA VALVULA DE TAL MODO, QUE CUANDO SE EXCITA MUEVE EL CUERPO (30) DE VALVULA HACIA AFUERA A PARTIR DE MIEMBRO (60) DE SELLADO CONTRA LA FUERZA DE UN RESORTE (38) DE VALVULA. EL PISTON (42) SE MUEVE AXIALMENTE EN EL ALOJAMIENTO (2) DE VALVULA Y TRANSMITE LAS FUERZAS ACTUANTES A PARTIR DE UN MIEMBRO (44) DE ACTUACION A UN MIEMBRO (50) DE TRANSMISION DE FUERZA. SOBRE EL PISTON SE DISPONE DE UN ELEMENTO (52) DE PARADA QUE SE EXTIENDE HACIA AFUERA CON TOLERANCIA AXIAL A TRAVES DE CAVIDADES (34,36) RADIALES EN EL CUERPO (30) DE VALVULA Y EL ALOJAMIENTO (22) DE VALVULA Y, CUANDO EL MIEMBRO (44) DE ACTUACION NO ESTA ACTUADO, SE DEFINE UNA POSICION INOPERATIVA COMPARTIDA DEL CUERPO (30) DE VALVULA Y DEL PISTON (42) MEDIANTE EL CONTACTADO DE UN TOPE (54) SOBRE LA CARCASA (10) DEL AMPLIFICADOR NEUMATICO. EN ESTA POSICION INOPERATIVA EL RESORTE (38) DE VALVULA SUJETA EL CUERPO (30) DE VALVULA CONTRA EL ELEMENTO (52) DE TOPE Y, AL MISMO TIEMPO, EL SEGUNDO ASIENTO DE VALVULA (32) CONTRA EL MIEMBRO (60) DE SELLADO.
