Abstract

UN APARATO DE DESAGUE DE INYECCION DE COMBUSTIBLE PARA SUMINISTRAR COMBUSTIBLE A UN MOTOR DE COMBUSTION INTERNA TIENE UNA BOMBA DE INYECCION 10 A LA QUE SE SUMINISTRA COMBUSTIBLE MEDIANTE UNA BOMBA DE ALIMENTACION DE BAJA PRESION 14 A TRAVES DE UN REGULADOR AJUSTABLE 16. UN PISTON 12 QUE FUNCIONA POR LA PRESION DEL FLUIDO SE MUEVE CONTRA LA ACCION DE UN MUELLE 13 PARA CONTROLAR LA SINCRONIZACION DE DISTRIBUCION DE COMBUSTIBLE MEDIANTE LA BOMBA DE INYECCION. SE APLICA COMBUSTIBLE BAJO PRESION AL PISTON A TRAVES DE UN PRIMER ORIFICIO FIJO 20 DE LA BOMBA DE ALIMENTACION. UN SEGUNDO ORIFICIO FIJO 22 Y UN ORIFICIO VARIABLE 23 ESTAN CONECTADOS EN SERIE ENTRE UN DRENAJE Y EL LADO CORRIENTE ABAJO DEL PRIMER ORIFICIO FIJO. EN PARALELO CON EL PRIMER ORIFICIO FIJO HAY UNA VALVULA DE CAIDA DE PRESION CONSTANTE QUE MANTIENE LA CAIDA DE PRESION A TRAVES DEL PRIMER ORIFICIO FIJO SUSTANCIALMENTE CONSTANTE CUANDO LA CAIDA DE PRESION SE HA ELEVADO A UN VALOR PREDETERMINADO.
