Abstract

EN UNA CARCASA (10) DE AMPLIFICADOR, DOS CAMARAS (12,14) SEPARADAS UNA DE OTRA POR MEDIO DE UNA PARED (16) MOVIL PUEDEN SER UNIDAS UNA CON OTRA A TRAVES DE UNA VALVULA (20) DE CONTROL, QUE MUESTRA UNA CARCASA (22) DE VALVULA CONJUNTA MOVIL AXIALMENTE CON LA PARED (16) CON UN PRIMER ASIENTO (24) DE VALVULA ASI COMO UN CUERPO (60) DE JUNTA SUJETADO PREVIAMENTE CON RESPECTO AL PRIMER ASIENTO DE VALVULA, MOVIL AXIALMENTE EN LA CARCASA DE VALVULA Y UN CUERPO (30) DE VALVULA. EL CUERPO (30) DE VALVULA MUESTRA UN SEGUNDO ASIENTO (32) DE VALVULA Y ESTA SUJETO PREVIAMENTE HACIA ADENTRO EN DIRECCION HACIA EL CUERPO (60) DE JUNTA, SIENDO MOVIL POR MEDIO DE UN EMBOLO (42) QUE PUEDE MOVERSE POR MEDIO DE UN MIEMBRO (44) DE ACCIONAMIENTO EN LA DIRECCION DEL CUERPO (60) DE JUNTA EN ARRASTRE HACIA EL EXTERIOR, Y POR MEDIO DE UN ELECTROIMAN (40) TAMBIEN INDEPENDIENTE DEL EMBOLO (42). EN EL EMBOLO (42) SE CONFIGURA UN TERCER ASIENTO (72) DE VALVULA QUE TIENEN UNA DISTANCIA (B) CON RESPECTO AL CUERPO (60) DE JUNTA, CUANDO EL CUERPO (30) DE VALVULA Y EL EMBOLO (42) SE ENCUENTRAN EN LA POSICION DE REPOSO, HACIENDO CONTACTO SIN EMBARGO EN EL CUERPO (60) DE JUNTA Y EVITANDO CON ELLO LA CORRIENTE DE ENTRADA DE AIRE EN LA PRIMERA CAMARA (12), CUANDO EL MIEMBRO (44) DE ACCIONAMIENTO QUEDA LIBRE, MIENTRAS QUE EL CUERPO (30) DE VALVULA ESTA SOPORTADO DEL ELECTROIMAN (40) EN UNA POSICION ALEJADA DEL CUERPO (60) DE JUNTA.
