Abstract (en)
[origin: WO03004865A1] The invention relates to a fuel supply device comprising a housing (1), in which a plunger-shaped component (5) is situated whereby being able to be longitudinally displaced inside a boring (3). Said boring is guided inside the boring (3) in a sealing manner with a guiding section (105) . The guiding section (105) borders, at one end, on a first fuel-filled space (19) and, at the other end, on a second fuel-filled space (15). At least one recess (30), which extends in an at least approximately peripheral direction, is provided inside the guide section (105) of the plunger-shaped component (5). Said recess extends at least over a portion of the periphery of the plunger-shaped component (5) and, when viewed in the longitudinal direction of the plunger-shaped component (5), has an asymmetrical cross-section.
