Definitions
- the present invention relates to a device air intake for internal combustion engines multicylinder intended in particular to equip the motor vehicles or road vehicles, and more particularly to an intake manifold adapted to receive a plurality of taps and an air filter.
- the air intake device of the engines internal combustion conventionally includes a collector admission also called dispatcher who has for function to port the filter output air, and the entrance of the various intake ducts in the cylinder head of the engine.
- a collector admission also called dispatcher who has for function to port the filter output air, and the entrance of the various intake ducts in the cylinder head of the engine.
- the intake manifold presents classically a body coming to be fixed on the cylinder head of the engine; this body generally comprises a distribution chamber large capacity also called plenum and several pipes that leave this distribution chamber to supply combustion air to each of the combustion chambers of the engine.
- the intake manifold of a combustion engine internal is usually connected to a number more or less important of depression taken serving to operate organs as diverse as the braking system or Master Vac, the EGR valve, the fuel return valve fitted to the injection rail, systems for adding non-combustible substances or secondary combustible substances crankcase gases, fuel vapors from the canister or recirculated flue gases, as well as the sensor for measuring the manifold pressure.
- Measuring the pressure in the collector admission that is necessary to order injectors is in fact operated classically at means of an absolute pressure sensor connected by a flexible pipe length adapted to a quilting opening in the distribution chamber.
- the measurement sensor of depression collector is usually positioned in the engine compartment outside the engine; such a provision obliges to provide fastening systems adapted and therefore also complicates the operations of engine mounting.
- the present invention therefore aims to remedy to these disadvantages through an admission device adapted including an intake manifold which brings together in a simple and economical way almost all tapping necessary for the operation of the engine and thanks to an air filter serving as a support for Pressure sensor.
- the air intake device according to the invention is defined to the claim 1.
- the filter air is characterized in that it comprises a suitable support to receive the pressure sensor.
- the support integrates means of clipping for easy assembly and disassembly pressure sensor.
- the admission device air shown is intended to equip an engine internal combustion spark ignition not shown in-line four-cylinder type equipping for example a motor vehicle.
- the admission device includes an air filter 1 extending near a collector referenced 2.

- the support 6 is more particularly designed to immobilize in position the sensor 3 by clipping.
- the support 6, adapted to the general rectangular shape of the sensor 3, essentially comprises a bottom wall 18 on which the sensor 3 comes to rest, as well as sidewalls 15 partially surrounding the wall 18 so as to form an open housing on the on the inside of which is positioned the sensor 3.
- the bottom wall 18 extends overhang in the direction intake manifold 2 being supported on three sides by ribs 16, it has a wide opening 19 opening on the free edge making facing the intake manifold 2 to allow passage of the pressure tap 4 connecting the pressure sensor 3 to the intake manifold 2 and allow the in place of the sensor 3 already connected to the pipe 4 in the housing defines by the support 6.
- the side walls 15 facing the two transverse ends of the sensor 3 are provided with lugs 17 able to come and press on the upper face of the sensor 3 and thus immobilize the latter on the support 6.
- the assembly and disassembly of the sensor 3 are operated in a simple way thanks to the elasticity of the side walls of the support 6 resulting from the plastic material used for form the two half-bodies 10 and 11 of the filter housing to air.
- the flexible thermoformed pipe 4 making office pressure setting typically extends between the sensor 3 and a corresponding tap 5 carried by the intake manifold 2 which leads to the right of the distribution chamber of the latter.
- Line 4 is, however, of shape and length adapted to minimize the waves of pressure prevailing in the distribution chamber of the collector.
- the present invention is also applicable for an internal combustion engine with ignition compression, especially in cases where the device air intake comprises a compressor or a flap EGR and where the pressure measurement in the collector intake is useful for the operation of the engine.

- This arrangement of the tails in two groups separate functions is to move sufficiently far taps 8 for the addition of substances to the combustion air taps 7 and 5 used for taking vacuum, in order to prevent any recovery of these substances through the catches of depression.
- each group of respective taps corresponds a single opening respectively 26, 27 opening into the distribution chamber 22.
- the associated opening 26 is shown at the taps 8 (the opening 27 associated with the taps 7 and 5 which extends in the extension of the opening 26 is perfectly similar to the latter with axial dimensions).
- This opening 26 is present in the form of an oblong hole 123 arranged through the wall of the manifold body defining the distribution chamber 22.
- the oblong hole 123 is surrounded by a wall 116 coming from molding with the collector body and projecting above it.
- the edge upper wall 116 forming a joint plane present a peripheral groove 29 adapted to receive a complementary shouldered boss 64 extending under the part 46 of the wafer around the various taps 8.
- the stitching 8 integrates an individual chamber 61 of substantially cylindrical having a flared entrance opening extending in the extension of the orifice 123, this chamber 61 opens with a connection end adapted 60 olive type (or fir type) extending perpendicular to the axis of the chamber 61.
- the connecting end 60 on which is connected the conduit of corresponding non-figured link is a part of the quilting 8.
- connection piece 9 is not directly integrated in the corresponding quilting 406 but clipped on the latter.
- the mouthpiece 9 includes a connection tip itself 80 forming a body with a cap 84 which is fixed removably on the stitching 406 constituted by a 406 adapted tube coming from molding with the wafer.
