Definitions
- the present invention relates to the field of electrical equipment for motor vehicles. It applies in particular, but not exclusively, to systems for pumping fuel, for example petrol, into a tank of a motor vehicle.
- the present invention relates to a filtering device against electrical and / or electromagnetic disturbances, for such equipment, in particular against the disturbances conveyed on the supply wires of such equipment.
- FIG. 1 The structure of a conventional fuel pumping equipment provided with a known filtering device has been shown diagrammatically in attached FIG. 1.
- a pump 10 actuated by a direct current electric motor whose inlet strainer 12 is placed near the bottom of a fuel tank 14.
- the fuel outlet of the pump 10 is referenced 13.
- the pump 10 is supplied electrically, from a battery 20, by two lines 22, 24. And these lines 22, 24 are associated with a filter 30.
- the filter 30 comprises two inductors of shock 32, 34 placed respectively on the lines 22, 24 and a capacitor 36 placed between the lines 22, 24, on the battery side 20.
- the ground line 24 is connected by an auxiliary electrical line 25, to the metal housing 11 of the pump 10.
- Many types of equipment illustrated in Figure 1 have been installed in the past on motor vehicles.
- the object of the present invention is to propose new means making it possible to reduce the level of electrical and / or electromagnetic disturbance, compared with known filtering devices.
- FIG. 1 previously described diagrammatically represents a known system conforming to the state of the art
- FIG. 3 represents a system in accordance with the present invention
- - Figure 4 shows a more detailed view of a pumping device according to a preferred embodiment of the present invention.
- an equipment comprising in a fuel tank 14 a pump 10 with casing 11 at least partially conductive comprising an inlet strainer 12 located near the bottom of the tank 14 and a fuel outlet 13.
- the pump 10 is actuated by a direct current electric motor, by two lines 22, 24, from a battery 20.
- the two lines 22, 24 are associated with a filter 30.
- This comprises two shock inductors 32, 34 placed respectively on the lines 22, 24, and a capacitor 36 placed between the lines 22 and 24 on the battery side 20.
- the line 24, in its section located between the shock inductor 34 and the battery 20, is connected to the electrically conductive casing 11 of the pump 10, by a component 40 of selfic nature. More precisely still, preferably, within the framework of the present invention, this component 40 is formed of a bar or a ferrite core, or even a ferrite ring. However, in the context of the invention the component 40 can also be formed from a coil.
- any increase in the high frequency response is suppressed, whereas this was the case in I with a setting to the direct mass of the filter, and that there is no intermediate peak as in III without grounding.
- the filter 30 can be fixed by any suitable means to the pump body 10 itself.
- the filter 30 can be clipped onto the pump 10 in the upper part thereof.
- FIG. 4 shows a preferred variant for installing the filter 30 in the upper part of the pump 10.
- this additional box 50 preferably made of metal, and forming a Faraday cage, must be mechanically and electrically connected to the metal casing 11 of the pump 10. It is also connected via the component 40 to the line. mass 24.
- This housing 50 forming Faraday cage is preferably composed of: '' a cylindrical sleeve 52 of coaxial vertical axis of the pump body 10 closed at the top by a transverse partition 54 perforated only to allow the passage of the fluid outlet 13 and the passage of the electrical connections to the filter 30 suitable for ensuring the DC motor supply. It has been found that the addition of such a box 50 forming a Faraday cage makes it possible to significantly reduce the radiated electromagnetic disturbances, in particular on the frequency band 30 MHz to 1000 MHz.
- the Faraday 50 cage housing can be the subject of numerous embodiments. In particular, it is conceivable that according to certain variants, this box 50 is not circular in revolution.
- the housing 50 is made of a copper alloy, for example a Cupro Nickel or a bronze alloy, for example CuSn3Zn9.
