Definitions
- fuel pump subject of the invention is a fuel pump with Minim ⁇ least a driven, rotating in a pump housing, having in its sides in each case at least one ring of vane chambers defining vanes impeller made of plastic and having arranged on both sides in the region of the guide vanes in the pump housing partially annular ducts which form with the blade chambers for conveying fuel delivery chambers, wherein an inlet channel opens into the one delivery chamber and the other delivery chamber in an outlet channel.
- Such fuel pumps are used for conveying fuel from a fuel tank to an internal combustion engine of a motor vehicle and are thus known.
- the impeller Upon rotation of the impeller, the fuel is sucked in via the inlet channel, brought to a higher pressure level and conveyed via the outlet channel and the electric motor of the fuel pump to a feed line, which conducts the fuel to the internal combustion engine.
- the pump housing is formed by a Pum ⁇ penboden and a pump cover. It is also known to additionally arrange a spacer between the pump bottom and a pump cover.
- the impeller For a rotation of the impeller ⁇ wheel in the pump housing, the impeller must be arranged at a distance from the pump housing parts. This means that there is a gap between one side of the impeller and the opposite part of the pump housing.
- the invention is therefore an object of the invention to provide a fuel ⁇ pump with an impeller made of plastic with high Festig ⁇ speed, which causes no damage to adjacent housing parts or arranged on them protective layers even with narrow gaps.
- the object is achieved with a fuel pump characterized in that the impeller contains carbon fibers embedded in the plastic.
- the impeller contains carbon fibers embedded in the plastic.
- the strength is achieved because the carbon fibers have a good tensile strength when embedded in the plastic matrix.
- the use of the carbon fibers prevents damage to opposite housing parts or protective layers arranged on them, since the carbon fibers tend to break during grinding or lapping so that even fewer fibers can come into contact with opposing components.
- Carbon fiber ends protruding freely from the side surfaces of the impeller are uncritical because carbon fibers are flexible so that they bend when in contact with other components. They thus do not have sufficient resistance that could lead to damage to adjacent components. Due to their material properties, the freely projecting carbon fibers additionally act as a kind of lubricant so that impellers according to the invention have good emergency running properties.
- Plastic is a polyphenylene sulphide or a synthetic resin based on phenolic resin.
- the proportion of admixed carbon fibers is between 15 and 50 percent by weight, depending on how high the desired mechanical strength is to be. This is among others by the
- the length of the carbon fibers can also be varied within wide limits.
- the areas may contain from 0.1 mm to 1 mm rei ⁇ chen. However, it has been found that carbon fibers with a length in the range of 1mm are particularly suitable.
