Abstract

Mejoras en la formación de tubos capilares para instalaciones de refrigeración, incluyendo refrigerante, caracterizadas porque comprenden las operaciones de formar un largo de tubería, longitudinalmente, a una configuración preseleccionada, de modo que sus extremos libres están dispuestos para conectarse con dicho sistema de refrigeración, incluyendo por lo menos una porción entre dichos extremos que se encuentre en un plano simple; colocando dicha porción de dicha tubería entremedias de dichos extremos libres en un medio formador; conectando por lo menos uno de dichos extremos libres a una fuente de presión constante, a través de un medio de control, teniendo medios para medir dicha presión, que pasa a través de la citada tubería; estrujando dicha porción de la tubería en el medio formador hasta que la tubería alcance una restricción intermedia predeterminada; curvando después dicha porción para procurar una restricción, generalmente en forma de U, teniendo miembros de rama divergentes desde un segmento de vértice arqueado y teniendo segmentos arqueados en la unión de cada uno de dichos miembros de rama con dicha tubería; conectando la citada tubería incluyendo dicha porción en una disposición de flujo de refrigerante en el citado sistema de refrigeración, moviendo por lo menos uno de dichos miembros de rama en relación con el otro para variar el diámetro de por lo menos una de dichas porciones arqueadas hasta que la restricción haga que el refrigerante, que pasa a través de dicha tubería alcance una presión final predeterminada.
