Abstract

UN INYECTOR PARA EL SUMINISTRO DE COMBUSTIBLE LIQUIDO A UN COLECTOR DE ADMISION DE AIRE EN UN MOTOR DE ENCENDIDO POR CHISPA TIENE UNA SALIDA (15) DEFINIDA EN UN TUBO (31). EL COMBUSTIBLE PENETRA A TRAVES DE UN ORIFICIO (30) FORMADO EN UN ASIENTO DE VALVULA (27). EL TUBO VA MONTADO EN UNA PARTE TUBULAR (32) DEL CUERPO DEL INYECTOR Y SEPARADO DEL ASIENTO DE VALVULA. ENTRE ESA PARTE Y EL TUBO VA DEFINIDO UN CONDUCTO DE CIRCULACION DE AIRE (34) Y EL PULVERIZADO DE COMBUSTIBLE QUE PASA POR EL ORIFICIO DE SALIDA ARRASTRA AIRE A TRAVES DEL CONDUCTO PARA MINIMIZAR EL GOTEO DE COMBUSTIBLE DESDE EL INYECTOR.
