Abstract

UN SISTEMA DE COMBUSTIBLE PARA UTILIZAR EN EL SUMINISTRO DE COMBUSTIBLE A UNA TOBERA DE INYECCION. EL SISTEMA CONSTA DE UNA BOMBA DE COMBUSTIBLE (15) DISPUESTA PARA CARGAR UN PRIMER Y SEGUNDO ACUMULADOR (10,13) Y MECANISMOS DE VALVULA DE CONTROL (29,30) OPERABLES PARA SELECCIONAR CUAL DE LOS ACUMULADORES SE UTILIZAN PARA SUMINISTRAR EL COMBUSTIBLE A LA TOBERA. EL SISTEMA INCLUYE ADEMAS UN MECANISMO DE VALVULA (24) INTERPUESTO ENTRE LA BOMBA DE COMBUSTIBLE Y EL SEGUNDO ACUMULADOR, SIENDO EL MECANISMO DE VALVULA (24) OPERABLE PARA PERMITIR QUE EL COMBUSTIBLE FLUYA DESDE LA BOMBA DE COMBUSTIBLE (15) AL SEGUNDO ACUMULADOR (11) UNA VEZ QUE LA PRESION DEL COMBUSTIBLE DENTRO DEL PRIMER ACUMULADOR (10) HAYA CONSEGUIDO UN VALOR PREDETERMINADO.
