Abstract

Un sistema de control de combustible para suministrar combustible con presión baja de combustible desde un depósito de suministro (11) a una entrada (12) de una bomba de combustible (13) y combustible con una presión alta de combustible desde una salida (22) de la bomba de combustible (13) a un motor (19) que comprende una válvula de dosificación de orificio variable (15) que tiene una entrada (22) para recibir combustible a alta presión desde la salida (22) de la bomba de combustible y una salida (24) para suministrar combustible al motor (19) a una presión intermedia entre las presiones alta y baja de combustible, y una válvula de derivación de combustible (23) para desviar selectivamente combustible desde la salida (22) de la bomba de combustible (13) de vuelta a la entrada (12) de la bomba de combustible (13) para mantener sustancialmente constante una diferencia de presión de combustible entre la entrada (22) y la salida (24) de la válvula de dosificación (15).
