Abstract |
AB |
[DE] Die Erfindung bezieht sich auf eine Brennstoffversorgungsvorrichtung für eine Gasturbine mit einem Ölsystem (1) und einem Brennstoffsystem (2), wobei das Brennstoffsystem (2) eine Niederdruck-Brennstoffpumpe (3) und eine nachgeordnete Hochdruck-Brennstoffpumpe (4) umfasst, deren Einlass über eine Rückführleitung (5) mit einer Auslassleitung (6) der Niederdruck-Brennstoffpumpe verbunden ist, dadurch gekennzeichnet, dass über ein mit einem Absperrelement (7) versehene Rückführleitung (8) Brennstoff einer Einlassleitung (9) der Niederdruck-Brennstoffpumpe (4) rückführbar ist.
[EN] The device has a fuel system (2) that comprises a low pressure fuel pump (3) and a subordinate high pressure fuel pump (4). An inlet of the high pressure fuel pump is connected with an outlet pipeline of the low pressure fuel pump by a feedback pipeline. Fuel of an inlet pipeline (9) of the low pressure fuel pump is fed back by another feedback pipeline that is provided with a closing unit. |
