Abstract (en)
[origin: WO2012076241A1] The invention relates to a fuel delivery system (16) of an internal combustion engine, comprising a rotary pump (22) that pumps fuel from a low-pressure region (17) into a high-pressure region (25), said rotary pump (22) having at least one inlet section (42) on the low-pressure side and at least one outlet section (44, 46) on the high-pressure side. The system also comprises a controllable valve device (32) that lies between the inlet section (42) on the low-pressure side and the low-pressure region (17) for controlling the delivered fuel flow. The rotary pump (22) comprises at least two outlet sections (44, 46) which lie one behind the other when seen in the direction of rotation and which are separate from each other, and at least one front outlet section (44), when seen in the direction of rotation, can be hydraulically connected or disconnected.
