Abstract
The invention relates to a delivery unit (2) comprising a swirl pot (5), a fuel pump (6) placed therein, and a filter, which is placed on the bottom (7) of the swirl pot (5) and which is radially flowed against. This filter is formed by shaped elements axially protruding from the bottom (7) of the swirl pot (5) whereby forming an axially extending gap (11, 11a, 11b) between every two adjacent shaped elements (10), and the filter surrounds an inlet opening (13) located in the bottom (7) of the swirl pot (5). At least one flow-through area (12) is situated perpendicular to the gaps (11, 11a, 11b) and perpendicular to the flow-through direction, this at least one area (12) connecting at least two adjacent gaps (11, 11a, 11b).
