    [0001] The technical field of the invention is that of air conditioning air distribution devices for military vehicles comprising a turret. Military vehicles with a turret need to be air conditioned and ventilated in order to ensure satisfactory living conditions for the crew and adequate operating temperatures for on-board equipment. The circulation of air in the box is conventionally provided by a ventilation unit coupled with an air conditioning and a ventilation network comprising ducts conveying air to the occupants and equipment. On the other hand, the ventilation of the turret is very delicate because of the confinement of the turret and its pivoting nature which makes it difficult to connect the ventilation network of the body with a ventilation network of the turret. Patent EP2145786 discloses a vehicle in which the ventilation unit is secured to either the turret or the body, and the vehicle has two air conveying circuits. A first for the distribution of air in the body and a second for the distribution of air in the turret, the two circuits being able to communicate with each other only in a particular angular position of the turret, a position for which an opening of the ventilation network of the turret is next to an opening of the ventilation network of the body. In other positions air no longer circulates directly between the two circuits and the turret ventilation circuit takes air directly into the box through the openings of the turret basket. Such a device does not allow to have a ventilation having the same performance for all the angular positions of the turret relative to the body and in particular if the turret enchaine several turns.
    [0002] The invention aims to solve this problem of non-permanence ventilation flows between box and turret. Thus, the invention relates to an air conditioning air distribution device for a turret of a vehicle rotatably mounted relative to a vehicle body, characterized in that it comprises at least one annular chute coaxial with the axis rotation of the turret and comprising at least a first flow orifice, chute having an annular opening which is concentric with it, the chute receiving a shutter ring which closes the opening of the chute, ring rotatable relative to the chute, and comprising at least a second air flow orifice, the chute being intended to be secured to the body (respectively of the turret) while the shutter ring is intended to be secured to the turret (respectively the checkout). Advantageously, the device comprises means ensuring the airtightness of the connection between the chute and the obturator ring. Advantageously, the device comprises two separate annular troughs each closed by a shutter ring, each trough having a first flow orifice and each shutter ring having a second flow orifice. The invention also relates to a vehicle comprising a turret comprising a turret ventilation network and a box comprising a body ventilation network, the networks each comprising pipelines for the conveyance of hot air and separate pipes for the purpose of delivery of fresh air, the turret being pivotally mounted on an axis relative to the body, characterized in that it comprises an air conditioning distribution device comprising at least one annular channel coaxial with the axis of rotation of the turret and provided with at least a first flow orifice, chute having an annular opening which is concentric with it, the chute receiving a shutter ring which closes the opening of the chute, ring capable of rotating relative to the chute and having at least one second air flow orifice, the chute being secured to the body (respectively the turret) ta ndis 10 that the shutter ring is secured to the turret (respectively the body). Advantageously, the channel or chutes are integral with the body and connected to the ventilation network box at the first port (s) (s), the shutter or rings 15 being secured to the turret and connected to the turret ventilation network by their second orifice (s). Advantageously, the vehicle comprises two separate annular troughs each closed by a shutter ring, each trough having a first flow orifice and each shutter ring having a second flow orifice, a first trough constituting a fresh air duct circuit. from the body to the turret and a second chute constituting a return circuit of hot air from the turret to the body. The invention will be better understood on reading the following description, with reference to the appended drawings, in which: FIG. 1 shows a lower three-quarter view of a turret of a vehicle according to the invention; . FIG. 2 represents an exploded view of an air distribution device according to the invention.
    [0003] Figure 3 shows a top three-quarter view of another embodiment of an air distribution device according to the invention. Figure 4 shows a partial sectional view of a vehicle having an air distribution device according to the invention. FIG. 5 represents a detailed view of a device according to the invention according to one embodiment. Figure 6 shows a detail view of a device 10 according to the invention according to one embodiment. Figure 7 shows a detailed view of a device according to the invention according to one embodiment. According to FIG. 1, a turret 1 of an armored military vehicle 15 (vehicle not shown) comprises a turret basket 2 intended to accommodate on-board equipment as well as an operator (equipment and operator not visible). The upper part of the turret is intended to emerge from a body 80 of the vehicle and comprises a shielded casemate 3. A ring gear 4 provides a pivot connection allowing the turret 1 to pivot relative to the body 80 of the vehicle around the body. 7. The turret 1 bottom 2 of the turret 1 has an electrical rotary joint 5 for electrical conduction between turret 1 and box 80 to allow continuity of electrical flows for control or power. Pipes 9a and 9b for conveying air in the turret extend between the bottom of the basket 2 of the turret 1 and the upper part of the turret, thus constituting a tilting aeraulic network 9. The aerial turret 9 comprises pipelines 9a for conveying fresh air from the box and separate pipes 9b to return to the box air that has been heated in the turret. It is obvious to those skilled in the art that the air conditioning and ventilation means can have a reversible operation which conveys hot air in turrets and extracts cooler air if the climatic and thermal conditions so require. According to another non preferred embodiment, it is also conceivable to route the air only in one direction and not to implement means for routing it in the other direction. The pipes 9a and 9b open into the upper part of the turret 1. In the lower part of the turret 1, they are connected to aeraulic rotating joints 10 at the bottom of the turret basket 2. The two rotating joints 10a, 10b of the illustrated case are coaxial with the turret pivot axis 7. A first rotary joint 10a is connected to the fresh air duct 9a of the ventilation network 9 of the turret and a second rotary joint 10b is connected to the hot air duct 9b. Thus, each rotary joint 10a and 10b is respectively dedicated to the delivery of fresh air to the turret 1 and hot air to the body 80. The rotary joints 10a and 10b are connected to a network 25 of pipes 17 of the cash register (17 cash network visible figure 4) providing fresh air from an air conditioning / ventilation unit and discharging the hot air to heat exchangers of the same unit. One part of the rotary joint is mechanically secured to the body and the other part is mechanically secured to the turret as can be seen in FIG. 4. According to FIG. 2, a rotary joint 10 comprises an annular channel 11 having in its upper part a annular opening 14 concentric with the chute 11. The chute 11 has at a point of its periphery a first orifice 12 for the flow of air to the air network 17 of the box 80.
    [0004] According to Figure 1, the first port 12 is intended to be connected to a pipe of the box and the chute 11 is intended to be fixed to the body 80 of the vehicle. An annular shutter ring 13 is intended to correspond with the opening 14. The ring 13 is able to rotate relative to the chute 11 and concentrically to it, forming an airtight connection between the ring 13 and the chute 11 once these two elements assembled. This connection will be better seen in FIG. 4. The ring 13 has a second airflow orifice 15. According to FIG. 1, the ring 13 is integral with the turret 1 at the level of the backplane 2 and the second orifice 15 is connected to a pipe of the tilting air network 9. It is of course possible to perform a reverse fixing, that is to say to make the chute 11 secured to the turret 2 and the ring 13 secured to the box 80 as shown in Figure 5. According to Figure 3, an air distribution device 10 according to another mode of embodiment comprises two rotating joints 10a and 10b which are concentric about the turret axis 7. Each rotary joint 10a, 10b comprises a first air flow orifice 12a, 12b intended to be connected to the ventilation network of the body and a second orifice 15a, 15b intended to be connected to the ventilation network 9 of the turret 1. The chutes 11a and 11b of each rotary joint 10a and 10b are integral with the body 80 of the vehicle while the rings 13a and 13b are integral with the basket 2 turret 1 (a reverse assembly would of course be possible). In this way, the device 10 provides a dual flow air distribution.
    [0005] In the first rotary joint 10a fresh air passes from the body to the turret 1 and in the second rotary joint 10b heated air passes from the turret to the body 80. Such an arrangement improves the efficiency of the cooling of the turret. In this way the turret 1 can freely rotate and this even chaining several consecutive rounds without limitation since the rings 13a and 13b provide an airtight connection with the ducts 11a and 11b. According to the embodiment of FIG. 4, the chutes 11 are joined by one of their sides 21. Moreover, the rings 13 form a single piece. Such an arrangement has the advantage of making the air distribution device 10 more compact and robust by uniting the elements that must move together such as the chutes 11a and lib on the one hand and the rings 13a and 13b of somewhere else. The upper flanges of the troughs 11 comprise sealing means 60 of O-ring type 60 which are contiguous with the lower face of the rings 13. These sealing means 60 will ideally be made of an anti-friction material to promote the pivoting of the rings. 13 which are guided in rotation by shoulders 70 which correspond with the interior of the inner and outer walls of the chutes 11. It is noted that the chutes 11 are integral with elements of the box 80. The rings 13 are in turn integral turret basket 1 to be able to follow all rotations about axis 7.
    [0006] FIG. 6 shows an embodiment where two troughs 11a and 11b are juxtaposed at their bottom. The openings 14a and 14b of the chutes both being oriented along a plane P perpendicular to the turret pivot axis 7. The opening 14a of the first trough 11a is disposed at the outer periphery of the ring formed by the trough 11a . The shutter ring 13a is then cylindrical and is placed opposite this peripheral opening 14a.
    [0007] The second chute 11b is located inside the ring formed by the first chute 11a and has an opening 14b directed towards the inside of the ring. The second chute llb is closed by a second cylindrical shutter ring 13b which is housed inside the ring 11b thus formed by the second chute 11b. The first and the second obturator ring 13a and 13b are integral with the body 80 of the vehicle at the level of body uprights 80a and 80b, while the chutes 11a and 11b are integral with the turret 2. To allow the assembly of the shutters 13a and 13b on the chutes 11a and 11b, the body of the chutes is made of two parts nestable one in the other in the direction of the axis 7 of the turret. As in the previous embodiments, low coefficient of friction seals allow pivoting of the chutes with respect to the sealing rings. According to the embodiment of FIG. 7, the chutes 11a and 11b equipped with their shutters 13a, 13b have a generally circular ring shape and are superimposed on one another. Each chute 11a, 11b forms one half of the torus and the corresponding shutter 13a, 13b forms the other half of the torus. Chutes 11a and 11b may pivot about turret axis 7 with respect to shutters 13a and 13b. For this purpose the chutes have circular grooves in which the shutters engage. In this case, the first chute 11a is secured to the turret basket 2 by fixing means 30. This same chute 11a is secured to the second chute 11b located below by other fastening means 31. The two sealing rings 13a and 13b plugging the chute openings lla and llb are integral with the body 80 of the vehicle by body amounts 80a and 80b. The rotation of the turret 2 therefore causes the chutes 11a and 11b to be driven while the sealing rings 13a and 13b are fixed with respect to the box 80. It will be noted that each air distribution device is intended to convey the low pressure air below 1.5 bar for air flow velocities up to 20 meters per second. The useful section of air ducting is between 25 and 400 square centimeters. 20
