Abstract

SE PRESENTA UN CONTROLADOR DE FLUJO DESLIZANTE PARA CONTROLAR EL FLUJO A TRAVES DE UN SEGMENTO DE BOMBEADO (10) UTILIZADO EN UN SISTEMA DE SUMINISTRO DE FLUIDO. EL CONTROLADOR DE FLUJO INCLUYE UNA CORREDERA (18) QUE SE MUEVE A LO LARGO DE UN CANAL DEFINIDO POR UNA MEMBRANA ELASTOMERICA (12) Y UNA RANURA DE TAMAÑO VARIABLE (60) FORMADA EN UN COMPONENTE RIGIDO. LA CORREDERA INCLUYE UNA BOLA PROYECTANTE (20) QUE PRESIONA LA MEMBRANA (12) CONTRA LA RANURA (60). EN UN EXTREMO, LA RANURA TIENE UN AREA DE SECCION DE CORTE MAXIMA PARA UNA POSICION DE FLUJO MAXIMO Y EN EL OTRO EXTREMO, LA RANURA (60) NO TIENE AREA DE SECCION DE CORTE PARA UNA POSICION DE DETECCION DEL FLUJO. LA CORREDERA Y EL SEGMENTO DE BOMBEADO TIENEN TOPES RESPECTIVOS (80, 314) PARA IMPARTIR UNA SEÑAL SENSORIAL AL OPERADOR CUANDO SE ACCIONA MANUALMENTE. SE DISPONE UNA IDENTACION INCLINADA PARA EL PULGAR (79) SOBRE EL EXTERIOR DE LA CORREDERA PARA FACILITAR EL MOVIMIENTO DESLIZANTE.
