Definitions
- the invention relates to a displacement pump designed as a G-rotor pump for delivering fuel in a motor vehicle with a driven G-rotor arranged between a base and a cover of a pump housing and with a spacer arranged between the base and the cover.
- G rotor pumps are usually assembled with an electric motor to form a delivery unit and are known in practice.
- the known G rotor pump has an inlet channel in the cover and an outlet channel in the bottom facing the electric motor. This flows axially through the G rotor pump.
- the spacer is essentially ring-shaped, surrounds the G-rotor and holds the lid at a designated distance from the floor. So that the bottom and the lid can be braced against each other. The lid that
- the base and the spacer are made of ceramic with a particularly high surface quality.
- the high surface quality ensures that an overflow of the delivered fuel from the area of the outlet to the area of the inlet is avoided.
- a disadvantage of the known G rotor pump is that the pump housing is designed to be very complex and thus has components which are cost-intensive to manufacture.
- the invention is based on the problem of designing a G rotor pump of the type mentioned at the outset in such a way that it can be manufactured particularly cost-effectively.
- this problem is solved in that the base and / or the cover are / are made of plastic.
- the pump housing can be assembled from components that can be manufactured particularly cost-effectively.
- the G rotor pump according to the invention can thereby be manufactured particularly cost-effectively.
- Another advantage of the G-rotor pump according to the invention is that noises of the G-rotor are particularly strongly dampened by the plastic components of the pump housing.
- the high surface quality required for the reliable operation of the G-rotor pump according to the invention could be achieved, for example, by coating the bottom and / or the cover. It contributes to a further reduction in the manufacturing costs of the G-rotor pump according to the invention [however, if the base and / or the cover are / are lobed on their side opposite the G-rotor. To simplify the assembly of the G-rotor pump according to the invention, it helps if the spacer is made in one piece with the cover arranged on the side of the G-rotor facing away from an electric drive. As a result, the base arranged on the side of the G rotor facing an electric drive can be designed to be flat. This contributes to a further reduction in the manufacturing costs of the G rotor pump according to the invention.
- this shows a longitudinal section through a fuel demand unit 1 with a device according to the invention
- the fuel delivery unit 1 has a housing 3 for accommodating an electric motor 4 and the G-rotor pump 2.
- the G-rotor pump 2 has a base 5 and a cover 7, which is kept at a predetermined distance from the base 5 via a spacer 6.
- the spacer 6 and the cover 7 are made in one piece here.
- a G rotor 9, which is fastened on a shaft 8 of the electric motor 4, is arranged between the cover 7 and the base 5.
- the shaft 8 has a flattened portion 10 for the rotationally fixed entrainment of the G rotor 9.
- the shaft 8 also has a shoulder 11 in the region of the G rotor 9. As a result, the G rotor 9 can only be connected to the shaft 8 in the position shown.
- the cover 7 has an inlet 12 and the base 5 has an outlet 13 of the G rotor pump 2.
- fuel is drawn in via the cover 7 and the G-rotor pump 2 flows axially.
- the housing 3 of the fuel delivery unit 1 has a connecting piece 14 for connecting a line, not shown. For clarity, the flows of the fuel are marked with arrows in the drawing.
- the cover 7 and the base 5 are made of plastic and lapped on their side facing the G rotor 9. As a result, the cover 7 and the base 5 have a particularly high surface quality and are able to reliably dampen noise.
- the G-rotor pump 2 has two screws 15 which pretension the cover 7 against the base 5.
- the cover 7 is biased against the floor 5 via the housing 3 of the fuel delivery unit. The use of the screws 15 can thus be dispensed with.
