Device for distributing air-conditioning air for a turret

The invention relates to a device for distributing air-conditioning air (1) for a turret (102) rotatably mounted with respect to a chassis (101), the device comprising a rotary joint (10) intended for electrically connecting the turret and the chassis and having a stator (10a) and a rotor (10b). The device (1) has a cover (4) forming a box (4) in which the rotor (10b) is housed and which is perforated by at least one air outlet (2). The cover (4) is integral with the rotor (10b) and located at the centre of a first disc (5). A second disc (6), which is pressed against the first disc (5), is integral with the stator (10a) and closes the box (4). This second disc (6) has an air inlet (3) arranged in the vicinity of the stator (10a), the side walls of the cover (4) being located at a distance from the rotor (10b) so that the air inlet (3) of the second disc (6) is always at least partly open into the housing for all angular orientations of the rotor (10b) with respect to the stator (10a).
