摘要： In a feed pump (2), guide vanes (9) fastened on a driven impeller (7) project into a recess (11) of a molding (8) annularly surrounding the impeller (7). The guide vanes (9) are located with a slight clearance opposite the wall of the recess (11). The guide vanes (9) can thereby have a particularly large surface. Moreover, a depositing of dirt in the radially outer region of the impeller (7) is avoided.

摘要： An electric motor for a fuel pump wherein fuel flows through the pump, includes spring elements provided for holding magnetic shells in the stator have a face which points toward a rotor and is flush with the magnetic shells. Turbulence in the flow of the fuel within the electric motor are thereby kept particularly low. The pressure loss during the flow through the electric motor thus becomes lower. The pump according to the invention consequently has high efficiency.

摘要： In a feed pump designed as a side-channel pump, an impeller is held so as to be slightly pivotable with respect to a shaft about an axis running transversely to the shaft. The impeller is thereby adaptable to tolerances of a casing. Rubbing of the impeller on the casing is also prevented as a result. The feed pump consequently generates a particularly low level of noise.

摘要： A feed pump designed as side-channel pump has a shaft for a rotationally fixed connection to an impeller. Two flattenings are arranged on the shaft so that they are nonparallel to one another. The impeller is thereby mountable on the shaft only in an intended position so that the impeller is rotated in an intended direction of rotation in a casing. The feed pump may therefore be assembled in a particularly simple way.
