It is thus ensured a flow regulation in the conduit.
- the regulating element when the regulating element is in one of its extreme positions or in its intermediate position, the regulating element ensures a selective connection of cooled and uncooled channels to the conduit.
- the valve thus ensures a dual function of flow control and selection of the channel connected to the duct.

- the disc 15 extends opposite the flanges 11, 12, 13 and the flange 10.
- the disk 15 is integral with one end of a shaft 17 whose opposite end is integral with a toothed sector 18 rotated by means of an electric motor 19 here in direct current.
- the disc 15 can thus be rotated between two extreme positions, namely: a first extreme position (shown in FIGS. 2 and 3) in which the passage opening 16 extends opposite the collar 11 and therefore the cooled track 5 (the disc 15 then clears the cooled track 5 and closes the uncooled track 6), and - a second extreme position (not shown) in which the through hole 16 is opposite the flange 12 and therefore the uncooled channel 6 (the disk 15 then clears the uncooled channel 6 and closes the cooled channel 5). Between these two extreme positions, the disc 15 has an intermediate position (not shown) in which the passage opening 16 is opposite the flange 13, the disc 15 closing the cooled and uncooled tracks 6. The two positions extremes and the intermediate position are at 120 ° very. This 120 ° arrangement allows for a given space to have the largest passage section.
- the valve 7 comprises a return element of the disc 15 in the intermediate position.
- the return element comprises two torsion springs 20, 21, helical and coaxial with the shaft 17, each having an end connected to the toothed sector 18 and an end connected to the body 8 to exert on the toothed sector 18 and therefore on the Disque 15 opposing return torques.

- the coil 22 is connected to the power supply means electrical not shown such that when the coil 22 is energized, it attracts the plate 23 and moves the shaft 17 and the disk 15 to the applied position of the disk 15.
- the displacement means also comprise a return member 15 of the disc in the unstuck position.
- the return member comprises a helical compression spring 24 which is disposed coaxially with the shaft 17 between the body 8 and a plate 25 fixed in translation and free to rotate relative to the shaft 17.
- the The plate 25 is freely rotatably mounted on a stepped sleeve 26 integral with the shaft 17 and bears axially on the shoulder of the bushing 26 and on the plate 23 by sliding shoes or needle bearings.
- the spring 24 pushes the plate 25 against a stop 27 integral with the body 8.

It is understood that when the disk 15 is in one of its two extreme positions, it ensures a maximum flow rate since the passage hole 16 is completely opposite one of the two channels 5, 6. On the other hand, when the disc 15 is between its intermediate position shutter and one of its positions In extreme cases, the passage opening 16 is only partially facing one of the two tracks so that the disk 15 masks part of this path. The disc 15 thus reduces the flow section of the exhaust gas flow from the channel in question and then allows a flow control.
- the electric motor 19 brings the disc 15 into its intermediate position, the coil 22 is energized and keeps the disc 15 in the applied position.
- the supply of the coil 22 is first cut so that the spring 24 can bring the disk 15 in the unstuck position and the electric motor 19 is powered to move the disc 15 to the desired position.
- the presence of the flanges 11, 12, 13 makes it possible to simplify the realization of a seal between the disc 15 and the seat thereof and to balance the forces exerted on the disc 15 when the latter is in position. applied.

- the return member of the disc 15 in the unstuck position comprises a permanent magnet 27, of circular shape, fixed on the periphery of the plate 23 opposite a magnetic plate 28 fixed in translation and free in rotation with respect to the body 8.
- the magnetic plate 28 is coaxial with the shaft 17 and is fixed to the body 8 by a rotating guide bearing and axial stops with needles.
- the plate 23 is made of magnetic material.
- the permanent magnet 27 has a diameter greater than that of the coil 22.
- the permanent magnet 27 is associated with an armature 29 for circulating the magnetic flux generated by the permanent magnet 27 so that the permanent magnet 27 generates a force of attraction of the magnetic plate 28.
- the armature 29 comprises, in a manner known per se, a saturating section restricting the flux generated by the permanent magnet 27 so as to limit the increase of the attraction force produced by the permanent magnet 27 as the The permanent magnet approaches the plate 28. This facilitates the movement of the disk 15 by the coil 22 when the coil 22 is energized to move the disk 15 in the applied position against the collars. lerettes 11, 12, 13.

- the permanent magnet 27 attracts the plate 28 and drives the disk 15 in the unstuck position.
- the difference in diameter between the permanent magnet 27 and the coil 22 is such that the permanent magnet 27 and the coil 22 are spaced apart from one another so that the permanent magnet 27 is only slightly or not, subject to the magnetic field generated by the coil 22.
- the toothed sector driven by the electric motor 19 is integral with the plate 23.
- the surface of the flange 10 extending on the side of the chamber 9 is smooth and the disk 15 has three protruding flanges (only two flanges are visible in Figure 5): a flange surrounding the orifice of passage 16 and two blind collars.
- the operation of the valve according to this variant is identical to that previously described.
- the regulating element could have a different structure from that described and be constituted for example by a sliding plate.
- channels 5 and 6 can be connected directly to the chamber 9 by means of connectors. nexion arranged externally on the body 8.
- the flanges 11, 12, 13 are optional.
- the valve 7 can be mounted upstream of the cooled and uncooled channels and not downstream as shown in FIG.
- the disk 15 In the recirculation phase, it is possible to bring the disk 15 in the applied position once it has been in the desired angular position connecting one of the channels to the conduit 14 if it is not desired that there is a leak on the other way. In case of modification of the angular position, the disk 15 is detached beforehand and, after pivoting, returned to the applied position.
