- the surface opening for the passage of the fluid, as and when the flap is rotated, is thus determined not only by the opening angle and the distance between the flap and the wall being vis-à-vis -vis but also by the length of the opening clearance E, that we can choose according to the progressivity of flow that we want to give to the valve.
- the length of the game E follows one or both of the following laws:
- the wall 62 comprises, for example, a first portion 62a in contact with which the flap is, at the mounting clearances, between its open position and its closed position, and a second portion 62b extending, according to the direction of the axis of articulation of the flap, from said first portion 62a.
- Said second portion has a lower concavity than that of said first portion so as to define said opening clearance E.
- Said first portion 62a and said second portion 62b are provided on either side of a connecting line 63, of curved shape, for example elliptical. In this way we obtain the rules of progression of the game E defined above.
- the axis of rotation 16 of the flap is, for example, eccentric and the flap 1 is oriented in a plane tangential to a cylinder centered on said axis.
- Said first portion 62a has, in particular, a profile in a cylinder whose axis is the axis of rotation of the flap. And said cylinder has a radius given by the distance between said hinge axis 16 of the flap and a distal edge or stop 63 of the flap 1, parallel to the hinge axis 16 of the flap.
- the wall 62 is provided, for example at the auxiliary duct 32 and the opening clearance E is located between the stop 63 of the flap and said wall 62, at its portion 62b.
- Said stop 33 is, for example, straight and the wall 62 of the auxiliary duct is configured to define said set E.
- the auxiliary duct 32 forms a bend in the direction of the orifice 35 and the portion 62a of the wall 62, preventing the passage of fluid, is provided on the opposite side to the direction taken by the elbow, for limit losses.
- Other configurations are of course conceivable depending on the direction given to the auxiliary conduit 32, including configurations where the portion 62a of the wall 62 preventing the passage of the fluid is in several parts.
- the shutter 1 is provided, for example, with a first wing 3 and a second wing 4.
- Said first wing 3, called shutter wing closes the window 33 of the body, when the shutter 1 is in position closure, and said second wing 4, said other wing, to close at least partially said first conduit 31, when the flap is in the open position.
- Said stop 33, movable vis-à-vis the wall 62 defining the game E is provided, for example, at the level of said shutter wing 3.
- the opening clearance E is zero and the stop 33 is in contact with the wall 62 over the entire length of said stop 33.
- the opening clearance is provided, for example, all along said stop 33. In other words there is fluid flow between the shutter 1 and the wall 62 at the entire length of the stop 33. In an intermediate position, the flow takes place only at a portion of said stop 33 (see Figure 3).
- Said body 30 may be made in two parts 30a, 30b, each part defining one of said ducts 31, 32, and having a corresponding opening to define said window 33.
- said two parts of the body 30 are distinct, subject to each other.
- Said two parts 30a, 30b are, for example, from foundry.
- said portions 62a, 62b are provided at one and the same part, in this case the portion 30b of the valve and the connection line 63 mentioned above is a dummy line.
- a seal 2 is provided, for example, between said two parts at said window 33 to play a sealing role between said two parts 30a, 30b vis-à-vis the outside of the valve.
- Said seal 2 has an opening 5 for the passage of the fluid from the conduit 31 to the other 32.
- Said opening 5 of the seal is provided, in particular, vis-à-vis the window 33 of the body 30.

- said shutter wing has a dimension y extending on both sides beyond the dimension y 'according to which extends the intermediate zone 6, at least at a junction zone between said intermediate zone and said shutter wing.
- the bearing surface 10 of the sealing wing 3 may thus have a contact zone 17, in the form of an angular portion of a ring, with the seal 2, on a first part of the periphery of the opening 5 of the seal, one side of said seal, while the bearing surface 12 of the other wing 4 has, on the other side of the seal, a zone of contact 18, on a complementary portion of the periphery of the opening 5 of the seal.
- the contact zone 17 provided by the shutter wing 3 also extends, for example, to the right of the intermediate zone 6, at the zones 7, 7 '. This reinforces the sealing and could have an intermediate zone 6 which does not flush the contour of the opening 5 of the seal.
- the opening 5 of the flap has a substantially rectangular contour, as well as the shutter 3. And the contact area 17 of said shutter wing 3 extends along three sides of said opening. As for the contact zone 18, it extends along the last side. Said intermediate zone 6 is provided vis-à-vis the contour of said opening 5 on a part of two of its opposite sides. Said other component 4 may also be rectangular.
- the seal 2 has, for example, a peripheral portion 39 and said planar zone 8 is set back from the peripheral portion. Such a seal is obtained, for example, by stamping.
- Said peripheral portion 39 may have extensions 40 forming a fastening flange on the body 30.
- Said body 30 further comprises, for example, a housing 37 for an actuating motor of the flap.
- said valve may comprise a transmission system, not shown, between an output shaft of the motor and the hinge shaft 21 of the flap.
- the valve is configured so that the shutter 1, in particular the other wing 4 is heat shield for the actuating motor.
