Abstract

EL DISPOSITIVO DE VELOCIDAD REGULABLE 1 DE TEMPORIZACION SE INSTALA EN EL ARBOL A A TRAVES DEL CUBO 2, ADAPTADO A SUJETARSE MEDIANTE UN ACOPLAMIENTO ROSCADO SOBRE EL EXTREMO DEL ARBOL A. EL CONJUNTO DEL CUBO 2 Y DEL EMBOLO O BUZO 5 SE RODEA POR UNA ENVUELTA, SUSTANCIALMENTE FORMADA POR UNA MORTAJA 8 CILINDRICA, QUE ENVUELVE AL EMBOLO 5, Y DE UNA CUBIERTA TERMINAL O CASQUETE 9, QUE CIERRA LA MORTAJA 8 SOBRE LO OPUESTO DESDE EL ARBOL A, Y RECIBE, DENTRO DE UN ORIFICIO 9A CIEGO AXIAL RESPECTIVO, EL EXTREMO LIBRE DEL CUBO 2, EN TANTO QUE TAMBIEN LIMITA, CON RESPECTO AL EXTREMO HOMOLOGO DEL EMBOLO 5, UNA CAMARA 21 ANULAR A LA CUAL SE ABREN LOS CONDUCTOS 4. ESTE ENFOQUE CONSTRUCCIONAL, ADICIONALMENTE PARA EVITAR TODO DESLIZAMIENTO AXIAL DE LA ENVUELTA 8, 9 RESPECTO AL CUBO 2, PUEDE PROPORCIONAR SEGURIDAD TOTAL DE QUE LA ENVUELTA DEL DISPOSITIVO DE VELOCIDAD REGULABLE ESTA TOTALMENTE CERRADA HERMETICAMENTE DEL COMBUSTIBLE (SERVOMEDIO) QUE SE SUMINISTRA AL INTERIOR DE LA CAMARA 21, SIN NECESIDAD DEL USO DE DISPOSITIVOS DE ESTANQUEIDAD. EL CASQUETE SE CONECTA A LA MORTAJA 8 PARA FORMAR UNA CONSTRUCCION UNITARIA TIPICAMENTE MEDIANTE UNA SOLDADURA LASERICA, A LO LARGO DE LA PATA 89 HACIA FUERA DE UNA SUPERFICIE DE CONEXION TOROIDAL, QUE TIENE UN PERFIL ESCALONADO, DEFINIDO POR SOPORTES COMPLEMENTARIOS RESPECTIVOS.
