Definitions
- the invention relates to a G-rotor pump, which in particular intended for use as a fuel pump in a motor vehicle is with an external rotor and with a relative to that External rotor movable internal rotor, in the case of a pumping room is limited between the outer rotor and the inner rotor.
- G-rotor pumps are often called tooth pumps or Eccentric pumps are known and are known from practice.
- the external rotor has an internal toothing and the inner rotor one of the internal teeth corresponding external toothing.
- the external toothing has one tooth less than the internal toothing, whereby the funding area is formed.
- the G-rotor pump used as fuel pump often the problem is that dirt particles between the runners advise and their abrasion and thus to a reduced The service life of the G rotor pump. Therefore, the G rotor pump usually a particularly close-meshed filter. Because dirt particles clog the filter quickly can, this design leads to a very cost-intensive Maintenance of the G rotor pump.
- a disadvantage of the known G rotor pump is that it is very sensitive to dirt particles in the flow is.
- the G rotor pump according to the invention also has heavily contaminated liquid to be pumped a particularly long lifespan. Therefore, the G rotor pump does not need one particularly fine-mesh filter. Therefore, the invention G rotor pump especially for use as a fuel pump suitable.
- the dirt particles collect according to another advantageous one Development of the invention through the flow in the Bags on and can stay there if the bags as recesses arranged in the tooth bases of the external rotor are.
- the dirt particles can be advantageous according to another Development of the invention simply by the centrifugal forces out of the pockets when the pockets as depressions arranged in the tooth bases of the inner rotor are trained.
- the G rotor pump according to the invention has a high absorption capacity of dirt particles when the pockets in all Tooth bases of the outer rotor or tooth bases of the inner rotor are arranged.
- Wear of the edges of the inner rotor and the outer rotor can be according to another advantageous development keep the invention particularly low when the bags over the entire height of the outer rotor and / or the inner rotor extend.
- the bags can be made according to another advantageous one Development of the invention is particularly easy to manufacture if they are groove-shaped.
- the bottom of the bags could be acute-angled or angular his.
- the dirt particle carries it according to another advantageous one Further development of the invention when the bags have a radius in their base area. Also will the notch effect of the pockets was kept particularly low.
- G rotor pump helps if the external rotor and / or the inner rotor is made of metal.
- G rotor pump helps if the external rotor and / or the Inner rotor is made of plastic.
- Figure 1 shows a fuel delivery unit 1 with a housing 3 for receiving an electric motor 4 and the G rotor pump 2.
- the G rotor pump 2 has a bottom 5 and one from the floor 5 via a spacer 6 to one provided Spaced lid 7.
- the spacer 6 and the cover 7 are made in one piece here.
- Between the lid 7 and the bottom 5 is a on a shaft 8 of the Electric motor 4 fixed inner rotor 9 arranged.
- the Shaft 8 has a rotationally fixed entrainment of the inner rotor 9 Flattening 10 and a paragraph 11. This is the inner rotor 9 can only be connected to the shaft 8 in the position shown.
- the inner rotor 9 has one shown in Figure 2 External toothing 12, which in an internal toothing 13 of a External rotor 14 engages.
- the lid 7 has an inlet 15 and the bottom 5 one Outlet 16 of the G rotor pump 2. This will make fuel sucked in through the cover 7 and the G-rotor pump 2 axially flows through.
- the housing 3 of the fuel delivery unit 1 has a connecting piece 17 for connecting a not shown Management. For clarification are in the drawing the flows of the fuel are marked with arrows.
- Figure 2 shows a greatly enlarged sectional view through the G-rotor pump 2 of Figure 1 along the line II - II Simplification of the drawing are the housing 3 and the spacer 6 of the G rotor pump 2 not shown.
- the external toothing 12 of the inner rotor 9 has one tooth less than the internal toothing 13 of the external rotor 14 a delivery chamber 18 through which the liquid to be delivered from the inlet 15 shown in FIG. 1 to the outlet 16 is funded.
- tooth bases of the internal toothing 13 of the external rotor 14 pockets 19 are arranged, which over extend the entire height of the outer rotor 14. In these Bags 19 collect in the liquid to be pumped Dirt particles. This prevents the Dirt particles on the flanks of the internal teeth 13 and Rub the external teeth 12 together.
- FIG. 3 shows a sectional view through a further embodiment the G rotor pump 2, which like that from FIG. 2 an inner rotor 20 with an external toothing 21 and one Has outer rotor 22 with an internal toothing 23.
- This embodiment differs from that of FIG. 2 in that that pockets 24 for holding dirt particles in the Tooth bases of the external toothing 21 of the inner rotor 20 are arranged are. Tooth bases of the internal toothing 23 of the external rotor 22, however, are smooth. Through this design dirt particles are transported into the Pockets 24 of the inner rotor 20 are added and by centrifugal forces flung out again.
