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).
Claims14
A delivery unit, with a baffle, with a fuel pump arranged therein and with a radial-onflow filter which is arranged on an underside of a bottom of the baffle and which is formed by shaped elements projecting axially from the underside of the bottom of the baffle, so that an axially running gap is formed in each case between two adjacent shaped elements, and which surrounds an inlet port arranged in the bottom of the baffle, characterized in that at least one region (12) for throughflow is arranged perpendicularly to the gaps (11, 11a, 11b) and perpendicularly to the throughflow direction, and in that the at least one region (12) connects at least two adjacent gaps (11, 11a, 11b) and wherein the at least one region (12) and gaps (11, 11a, 11b) define a fuel filter media.
