Definitions

the invention relates to a fuel pump according to the preamble of claim 1.
Such a fuel pump is disclosed, for example, in EP 0 603 524 B1 and already shows measures that can be used to operate the pump on axial walls of the Allow impeller forces to partially cancel out.
the object of the invention is to find measures with which a generic fuel pump even in transition operation without wear and disturbing pump noises can be operated.
Fig. 1 shows a longitudinal section of a fuel pump 1 with a fuel-cooled Electric motor 2 and a side channel pump unit 3, the pump wheel 4 in each axial wall 5, 6 has a blade ring 7, 8, which interacts with one side channel 9, 10, as shown in Figs. 2 and 3, the first in the direction of flow Side channel 9 connected to the second side channel 10 via a connecting channel 11 and the axial walls 5, 6 of the pump wheel 4 surface areas 12, 13 of a certain size have hermetically sealed by housing walls 14, 15 and with those selected in Side channel sections are subjected to prevailing pressures.
each vane chamber 21 has a differently configured one Single chamber 19 is connected, these two chambers 21, 19 approximately one cover the same area, so that the current pressures arising forces, since directed against each other, each individual vane chamber 21 or Cancel single chamber 19.
a ratio of two or more vane chambers can be used 21 to a single chamber 19, the area size of the single chamber then being provided 19 correspondingly twice or several times as large as that of the vane chamber 21 is. It goes without saying that then only one of the blade chambers 21 has a channel 22, which leads into the single chamber 19.
Fig. 1 shows, that the cross section of the individual chambers 19 in the radial direction is carried out constantly, d. H. with increasing radial distance from the center of the pump wheel the depth of the single chamber 21 decreases because the width between the ribs 20 enlarged with increasing radial distance.
