Abstract: A fuel injection device having an injection valve on which an atomizing grid is arranged. The disk-shaped atomizing grid is arranged downstream of a valve seat face and is equipped with an atomizing structure which at least partially possesses variations in cross section in the axial direction, over the thickness of the atomizing grid. As a result of the geometry of the atomizing grid, the fuel is atomized particularly finely into very small droplets without auxiliary energy. The fuel injection device is particularly suitable for use in fuel injection systems of mixture-compressing spark-ignition internal combustion engines.

Abstract: In a liquid pump of the side channel type, particularly an electric fuel pump, comprising a suction cover (11) having an inlet aperture (12), an intermediate casing (13) having an outlet aperture (14), and a pump impeller (15) enclosed therebetween, and also comprising concentric side channels (21, 22) which are formed in mutually oppositely situated surfaces (111, 131) of the suction cover (11) and intermediate casing (13) and into which lead an inlet opening (12) and an outlet opening (14) respectively, the geometry of the outlet opening (14) is selected, for the purpose of reducing noise and achieving greater smoothness of running, such that its aperture wall (141) bounding the end of the side channel (22) in the intermediate casing (13) extends outward with a concave curvature, at least in the side channel region, from the inner surface (131) of the intermediate casing (13) onward, and that on the other hand the geometry of the end of the side channel in the suction cover (11) has a configuration such tha
