Abstract

SON CONOCIDOS DISPOSITIVOS PARA LA INYECCION DE UNA MEZCLA COMBUSTIBLE-GAS CON UN MANGUITO DE CERCADO DE GAS EN FORMA DE OLLA. EN UN SISTEMA DE INYECCION DE ESTE TIPO LA PIEZA DEL CILINDRO DEL MANGUITO DE CERCADO DE GAS CON SU PARED INTERNA DESCANSA EN EL PERIMETRO DE LA VALVULA DE INYECCION DEL COMBUSTIBLE Y EN LA PARED INTERIOR DISPONE DE CANALES DE CONDUCCION DE GAS EN FORMA DE RANURA. UN MANGUITO O CASQUILLO DE CERCADO DE GAS DE ESTE TIPO MUESTRA O PRESENTA UN MONTAJE COSTOSO Y ALTOS COSTE DE FABRICACION PARA CONSEGUIR UN CENTRADO EXACTO DEL MANGUITO CONTRA LA VALVULA DE INYECCION DEL COMBUSTIBLE PARA EL CUMPLIMIENTO DE TOLERANCIAS DE FABRICACION MUY ESTRECHAS. POR EL CONTRARIO EL NUEVO DISPOSITIVO TIENE LA VENTAJA DE UNA FABRICACION SENCILLA Y DE COSTE ADECUADO PARA CONSEGUIR UN CENTRADO MUY EXACTO DEL MANGUITO (1) CONTRA LA VALVULA (7) DE INYECCION DEL COMBUSTIBLE. LOS LISTONES (55) GUIA EN DIRECCION RADIAL HACIA EL INTERIOR DESCANSAN CON SU CARA FRONTAL (57) EN EL PERIMETRO DE LA VALVULA (7) DE INYECCION DE INCOMBUSTIBLE Y CENTRAN DE UNA FORMA SENCILLA EL MANGUITO (1) CONTRA LA VALVULA (7) DE INYECCION DEL COMBUSTIBLE. EL DISPOSITIVO PROPUESTO PARA LA INYECCION DE UNA MEZCLA COMBUSTIBLE-GAS ES APROPIADO ESPECIALMENTE PARA UN SISTEMA DE INYECCION EN UNA TUBERIA DE ASPIRACION DE UNA MAQUINA DE COMBUSTION INTERNA CON ENCENDIDO EXTERIOR DE UNA MEZCLA PRECOMPRIMIDA.
