Definitions
- the invention relates to a side channel pump, which is provided in particular for delivering fuel in a motor vehicle, with an impeller rotating in a pump housing, with a collar arranged in an end face of the impeller and with a collar arranged opposite the collar in the housing, from an inlet to an outlet extending partially annular channel.
- a disadvantage of the known side channel pump is that, seen from the axis of rotation of the impeller, the flow between the impeller and the housing can penetrate in the radially outer region.
- the residual dirt in the medium leads to wear on the axial sealing surfaces located radially outside the delivery chamber and thus to a reduction in efficiency. This effect is further intensified, in particular, by heavily contaminated medium to be conveyed.
- the invention is based on the problem of designing a side channel pump of the type mentioned at the outset in such a way that it avoids wear on the axial sealing surfaces of the delivery chamber.
- This problem is solved according to the invention in that the outer boundary of the part-annular channel has a larger diameter than the outer boundary of the ring of the blade chambers.
- the side channel pump according to the invention is structurally particularly simple if the partially annular channel and the blade chambers each have the same width and if the radius R1 from the axis of rotation of the impeller to the partially annular channel has the radius R2 of the ring of the blade chambers by 0.1-1.5 mm exceeds.
- This design protects the axial sealing surfaces of the blade chambers and the part-ring-shaped channel from wear.
- the invention permits numerous embodiments. To further clarify its basic principle, one of these is shown in the drawing and is described below.
- the fuel pump has a side channel pump 2 according to the invention, driven by an electric motor 1.
- the side channel pump 2 has a housing 3 with two housing parts 4, 5, between which an impeller 6 driven by the electric motor 1 is rotatably arranged.
- An inlet 7 and an outlet 8 are arranged in the housing 3.
- the impeller 6 has on its end faces two rings of vane chambers 10 delimited by guide vanes 9.
- Shovel chambers 10 which are opposite one another are connected to one another.
- the rings of the vane chambers 10 are arranged in the form of partially annular channels 11.
- the partially annular channels 11 extend from the inlet 7 to the outlet 8 and, together with the vane chambers 10, form a delivery chamber for delivering fuel.
- the side channel pump 2 is therefore flowed through axially by the fuel to be delivered.
- circulation flows occur in the delivery chamber, which are accelerated away from the axis of rotation of the impeller 6 in the blade chambers 10.
- the flows of the fuel are marked with arrows in the drawing.
