Abstract

UN APARATO DE BOMBEO DE COMBUSTIBLE, QUE CONSTA DE UN CUERPO (10) QUE DEFINE UN PRIMER ORIFICIO (11) DENTRO DEL CUAL SE ENCUENTRA UN EMBOLO DE BOMBEO (12) RECIPROCANTE. EL PRIMER ORIFICIO (11) SE COMUNICA CON UNA VALVULA DE DERRAME (14). UN PISTON GUIA (30) SE MUEVE DENTRO DE UNA GALERIA GUIA BAJO LA INFLUENCIA DE LA PRESION DENTRO DEL PRIMER ORIFICIO (11). UN ELEMENTO DE PISTON (33) SE DESLIZA DENTRO DE UNA PERFORACION CIEGA (32) DISPUESTA EN EL PISTON GUIA (30), DE MANERA QUE CON EL MOVIMIENTO DEL MISMO (30), EL COMBUSTIBLE DENTRO DE LA PERFORACION CIEGA (32) SE PRESURIZA A UNA PRESION MAYOR QUE LA DEL COMBUSTIBLE DENTRO DEL PRIMER ORIFICIO (11). UN MECANISMO DE PASO (37,38) CONECTA LA PERFORACION (32) CON UNA TOBERA DE INYECCION DE COMBUSTIBLE (20).
