Definitions
- the present invention relates to the field of fuel drawing assemblies for motor vehicles.
- the present invention applies in particular to drawing assemblies comprising an electric pump immersed in the tank of the motor vehicle.
- damping components comprising a deformable membrane, dampers based on Helmholtz resonators or of hydraulic capacity, or else dampers formed of hollow bodies with thin walls of flexible and elastic material and containing a compressible gas (see for example documents FR-A-2 709 791 and US-A-5 122 039).
- the present invention now aims to provide a new pulsation damper adapted to be integrated into a fuel pumping assembly.
- a pumping assembly comprising on the outlet of the pump a damper formed by a sleeve made of compressible material.
- the present invention also relates to tanks equipped with such a pumping assembly.
- FIG. 1 represents a schematic view partially in section of a pumping assembly in accordance with the present invention
- - Figure 2 shows a longitudinal sectional view of a damping sleeve according to the present invention.
- a pumping assembly 10 of conventional general structure comprising a plate 12 adapted to be fixed on the upper wall of a fuel tank, a support body 14 connected to this plate 12 and which houses an electric pump 20, the inlet of which is provided with a filter 22 and the outlet of which is formed by a tubular end piece 24.
- the plate 12 carries electrical contacts 30 and several tubes, including one tube 32 which projects downwards from the plate 12 to receive the tubular end piece 24.
- annular seal 40 is interposed between the external surface of the tubular end piece 24 and the internal surface of the tubing 32.
- This annular seal 40 can be the subject of numerous variant embodiments. It is preferably a double lip seal as illustrated in FIG. 1, resting respectively on the external surface of the tubular end piece 24 and on the internal surface of the tubing 32, which lips are connected together by a radial partition in the shape of a crown, at one of their axial ends.
- a metal cup 34 for example made of stainless steel, is fixed, for example driven, to the base of the tube 32 to hold the seal 40 and the damping sleeve 42.
- a damping sleeve 42 is placed inside the tube 32.
- the sleeve 42 is thus placed in the fuel line connecting the outlet of the pump 20 and the outlet of the plate 12 designed to be connected to the site of use (carburetor or injector rail), in contact with the fuel.
- the sleeve 42 is preferably formed from a sealed closed cell foam material, for example based on PVC-Nitrile or fluorosilicone. michell, -. michelle, - 98/28536
- the sleeve 42 is advantageously made of a material of low density, typically of the order of 250 kg / m3.
- the material making up the sleeve 42 has a Young's modulus of between 0.4 and 0.8 MPa.
- the length of the sleeve 42 is of the order of 26mm, its internal diameter is of the order of 10mm and its external diameter is of the order of 18mm.
- This sleeve 42 makes it possible to damp the pulsations by compensating for the variations in volume generated by these pulsations. It will be noted that the integration of the damping device 42 according to the present invention, in the assembly ensuring the connection of the pump 20 / mechanical support 12 allows simple installation without requiring a specific mechanical fixing system.
- the present invention thus allows effective damping of pulsating noises, at low cost and without increasing the size of the known pumping assemblies.
