Abstract (en)

[origin: EP0183581A1] 1. A ventilation device having sleeves, in particular for the cooling circuit of a thermal transfer fluid of a heat engine, comprising an inlet sleeve (17; 22) and an outlet sleeve (19; 23), one (17; 23) thereof being rotatable relative to the other and connecting the ends of the blades (2; 25) of a propeller (1; 23), characterised in that said sleeves are coaxial and juxtaposed, the thickness (ES; E19; E23) of the material constituting said outlet sleeve (19; 23) is at leat equal to the thickness (EE; E17; E22) of the material constituting said inlet sleeve (17; 22) and the inside diameter (DS; DE19; D23) of said outlet sleeve (19; 23) is at least equal to the inside diameter (DE; DE17; D22) of the inlet sleeve (17; 22) and at the most equal to the inside diameter of the inlet sleeve (DE; D17; D22) plus the thickness (EE; E17; E22) of the inlet sleeve.
