Definitions
- the invention relates to a wet-running DC motor for fuel pumps according to the Preamble of claim 1.
- Such fuel pumps are required for internal combustion engines in vehicles be used.
- Fig. 1 shows a cross section through a wet-running DC motor 1 for a fuel pump for internal combustion engines, with a commutator 2 and carbon brushes 3.
- the carbon brushes 3 are each loaded by a spring 4 against the commutator 2.
- the DC motor 1 and a pump, not shown, are in one, not shown Housing arranged and flowed through by fuel.
- the commutator 2 is formed from carbon lamellae 5 and the carbon brushes 3 have a brush running surface 6 corrugated in the direction of rotation.
- the brush running surface 6 has a radial center offset 8 directed against the direction of rotation (arrow) (FIG. 3), as a result of which the carbon brush 3 can lie against the commutator 2 with a full surface 6 within a carbon guide 9 despite an inclined position.
- the corrugation of the brush running surface 6 is achieved by ribs 10 arranged in parallel (FIG. 2), which have a triangular cross-sectional surface 11 (FIG. 4), the triangular tip 12 of which ends in the region of the brush running surface 6.
- a special embodiment provides that the ribs 10 a distance 13 from each other about 0.5 mm and have a tip height 11 of about 0.2 mm, the radius center offset 8 is about 0.5 mm.
