DISPOSITIF DE TRANSPORT DE CARBURANT POUR UN MOTEUR À COMBUSTION INTERNE AINSI QUE PROCÉDÉ POUR LE TRANSPORT DE CARBURANT DANS UN DISPOSITIF DE TRANSPORT DE CARBURANT

摘要

The invention relates to a fuel-pumping device (1) for a fuel injection device of an internal combustion engine with a large high-pressure pump (16) and a small high-pressure pump (14) arranged in parallel, wherein fuel can be pumped by the large high-pressure pump (16) and by the small high-pressure pump (14) from a low-pressure region (13) into a high-pressure region (18). The high-pressure region (18) is connected to at least one injector (21). A control device (30) is provided, which can be used to conduct the entire pump output of the large high-pressure pump (16) or the small high-pressure pump (14) into the low-pressure region (13) via a discharge line (15).
