Abstract

UN APARATO DE SUMINISTRO DE COMBUSTIBLE PARA SUMINISTRAR COMBUSTIBLE A UN MOTOR DE IGNICION A COMPRESION QUE CONSTA DE UN MIEMBRO DE DISTRIBUCION ROTATORIO (11) QUE TIENE UN RECORRIDO DE DISTRIBUCION (13) QUE PUEDE REGISTRAR A CAMBIO CON PUERTAS DE SALIDA (14) CONECTADAS A LAS TOBERAS DE INYECCION DEL MOTOR. EL COMBUSTIBLE SE SUMINISTRA AL RECORRIDO DE DISTRIBUCION DESDE UN ACUMULADOR (20) BAJO EL CONTROL DE UNA VALVULA (18). EL ACUMULADOR ESTA CARGADO CON COMBUSTIBLE POR MEDIO DE UNA BOMBA A ALTA PRESION (8) QUE ES UNA BOMBA ACCIONADA POR LEVA Y EL COMBUSTIBLE SE SUMINISTRA A LA BOMBA DE ALTA PRESION A TRAVES DE UNA BOMBA A BAJA PRESION (31). SE SUMINISTRA UNA VALVULA (34) PARA CONTROLAR LA PRESION DE SALIDA DE LA BOMBA DE BAJA PRESION DE MODO QUE LA CANTIDAD DE COMBUSTIBLE SUMINISTRADO A LA COMBA DE ALTA PRESION PUEDA VARIARSE CON EL PROPOSITO DE CONTROLAR LA PRESION DEL COMBUSTIBLE DENTRO DEL ACUMULADOR. ESTA PRESION SE PERCIBE A TRAVES DE UN TRANSDUCTOR (35) QUE SUMINISTRA UNA SEÑAL A UN SISTEMA DE CONTROL (22) QUE CONTROLA EL FLUJO DE LA CORRIENTE ELECTRICA EN LA VALVULA (34).
