Abstract

The invention relates to a fuel pump (1), which in particular serves as a pump arrangement for fuel-injection systems of air-compressing, self-igniting internal combustion engines, comprising at least one housing part (3), a first toothed wheel (15) and a second toothed wheel (16). The toothed wheels (15, 16) are arranged in the housing part (3). Furthermore, the toothed wheels (15, 16) intermesh in order to form a gear pump (17). The invention further relates to an inlet or return (35, 36) for the gear pump (17), which inlet or return (35, 36) is provided in the housing part (3).
