Abstract

SE TRATA DE UN DISPOSITIVO PARA MEDIR EL FLUJO REFRIGERANTE, PARA SU UTILIZACION EN UN SISTEMA DE REFRIGERACION, QUE LLEVA UN CUERPO (20) CON UN PASO DE FLUJO QUE SE EXTIENDE A TRAVES DEL MISMO. UN PISTON (62) CON UN PUERTO DE MEDICION DE FLUJO (80) QUE SE EXTIENDE A TRAVES DEL MISMO, DISPUESTO DE FORMA MOVIL DENTRO DEL PASO DE FLUJO. UN MIEMBRO ALARGADO (60) SE EXTIENDE HASTA EL PUERTO DE MEDICION (80) DEL PISTON (62) Y COOPERA CON EL PUERTO PARA DEFINIR UN PASO DE MEDICION DE FLUJO (81) ENTRE AMBOS. EL MIEMBRO ALARGADO (60) ESTA CONFIGURADO DE MANERA QUE HAGA VARIAR LA SECCION TRANSVERSAL DEL PASO DE MEDICION DEL FLUJO (81) EN FUNCION DE LA POSICION DEL MIEMBRO CON RESPECTO AL PUERTO DE MEDICION. LLEVA MEDIOS (70, 72) DE SOPORTE DEL MIEMBRO ALARGADO (60) DENTRO DE LA ESTRUCTURA Y MEDIOS DE CONTROL DE LA POSICION AXIAL RELATIVA DEL MIEMBRO ALARGADO (60) Y EL PISTON (62) UNO CON RELACION AL OTRO, EN FUNCION DE LA PRESION DIFERENCIAL QUE PASA POR EL PISTON (62). EL DISPOSITIVO DE EXPANSION DEL REFRIGERANTE PERMITE LA RESPUESTA A CIERTAS CONDICIONES DE PRESION Y FLUJO DENTRO DEL SISTEMA DE REFRIGERACION, PARA SUMINISTRAR AREAS DE EXPANSION OPTIMAS DENTRO DEL DISPOSITIVO A UNAS CONDICIONES DE PRESION Y FLUJO DADAS.
