Definitions
- TITLE SET COMPRISING AN AIR FILTER AND AN AIR METERING VALVE
- the present invention relates to the field of the air intake line of an internal combustion engine. More particularly, the subject of the invention is an assembly comprising an air filter and an air metering valve.
- Document FR3069892 discloses a heat engine air filter comprising a hollow body and a cover closing the hollow body.
- the cover is removable to allow replacement of the filter cartridge housed inside the body.
- the filter includes a seal interposed between the filtered air outlet on the cover and a throttle body inlet.
- the cartridge maintenance operation requires the removal of the cover and this seal.
- Several factors such as thermal shocks, vibrations and pressure impact the shape of the seal and these deformations make it difficult to use this same seal without obtaining an air leak between the throttle body and the cover, or perfect filtration and sufficient air flow on an engine are essential conditions for its longevity, for normal energy consumption.
- an air filter comprising a cover, this cover comprising an opening, - an air metering valve comprising a filtered air inlet,
- the indexing means comprise a male part cooperating with a female part.
- the male part is a tab projecting from the seal.
- the tongue extends radially with respect to the plane of the seal.
- the female part comprises a notch.
- the notch is carried by a rib surrounding the seal.
- the rib is carried by the air metering valve or by the cover.
- the air filter comprises a filter cartridge with a seal positioned along a circumference of the filter cartridge, the cover further comprising a rib bearing against the seal.
- the invention also relates to an internal combustion engine, characterized in that it comprises an assembly according to any one of the previously described variants.
- FIG 1 is a perspective view of an air filter for an intake line of a heat engine according to the present invention.
- FIG 2 is a longitudinal sectional view of the air filter of Figure 1.
- Figures 1 and 2 show assembly 1 comprising an air filter 2 for an intake line of an internal combustion engine.
- an engine can equip a motor vehicle.
- the air filter 2 can be attached to the body of the vehicle or to a part of the engine, such as for example a cylinder head cover or an oil separator.
- Set 1 includes another air metering valve 3 still conventionally referred to as the butterfly housing.
- the air filter 2 comprises a hollow body 4 in which is housed a filter cartridge 5, for example of substantially parallelepipedal shape.
- the hollow body 4 of the air filter 2 comprises, on one of its side faces, a fixing device 6 with the corresponding engine part, of the quarter-turn locking device type.
- a lid 7 closes the hollow body 4 removably to allow replacement of the filter cartridge 5.
- the lid 7 is made in a single part.
- the hollow body 4 and the cover 7 are for example made of a rigid plastic material, in particular of polyamide.
- the cover 7 is intended to close a first opening 8 of the body 4 extending in a substantially horizontal plane P1 and a second opening 9 of the hollow body 4 extending in a plane P2 substantially orthogonal to the plane P1, in other words, vertical.
- the lid 7 is fixed to the hollow body 4 using at least one fixing device, the dismantling of which can be carried out manually without tools, such as an interlocking hinge 10.
- the filter cartridge 5 delimits with the hollow body 4 an upstream dirty air chamber 11 into which an air inlet 12 opens, intended to be in communication with the front facade of the vehicle for the air intake.
- a clean air downstream chamber 13 is also delimited by the filter cartridge 5 and the cover 7.
- a seal 14 is interposed between the hollow body 4 of the air filter 2 and the cover 7. This seal 14 is positioned along a circumference of the filter cartridge 5. This seal 14 of rectangular shape extends along the horizontal plane P1. This seal 14 is for example made of a material based on polyurethane foam.
- Another seal 15 is interposed between the downstream air chamber 13 of the cover 7 of the air filter 2 and a filtered air inlet of the valve 3 for air metering.
- This seal 15 is located around the second opening 9.
- This ring-shaped seal 15 extends along the vertical plane P2.
- This seal 15 provides a seal between the filter 2 and the valve 3 air metering.
- This seal 15 is advantageously a lip seal but could alternatively be of another type, such as an O-ring for example.
- indexing means are provided for indexing the gasket 15 with respect to the cover 7.
- indexing means here consist of a male part in the form of a tab 16 projecting from the gasket 15.
- the tongue 16 is provided to be housed in a female part in the form of a notch 17.
- the tongue 15 extends radially with respect to the joint plane.
- this notch 17 is provided on the air metering valve 3 and carried by a rib 18. This rib at least partially surrounds the seal 15.
- the rib 18 and the notch 17 could be carried by the cover.
- ribs 19, 19' are arranged so as to bear against the sides forming the width of the seal 14 of the filter cartridge 5, in order to prevent the displacement of the filter cartridge 5 and prevent the passage of unfiltered air.
- Indexing allows the air filter seal to return to its initial position after disassembly/assembly and after each maintenance operation.
- the invention makes it possible to avoid replacing the seal during each cartridge maintenance operation. It is a reusable seal thanks to its indexer, which means fewer After-Sales parts to store and manage.
- the invention allows a longer life of the cartridge thanks to its regular maintenance, accessibility, ergonomics disassembly/assembly.
