Summary:A sealing device for a rotary machine, such as a motor for vehicle, which prevents transfer of air from a bearing assembly to a gear box or vice versa thereby to isolate the two components from each other and from the other parts therearound. The sealing device being particularly adapted for an arrangement in which a rotating shaft extends through the bearing assembly or gear box, in that a jet of air is supplied to the portion of the bearing assembly or gear box through which the shaft extends, so that an air layer with a pressure sufficiently higher than that around the portion through which the shaft extends is formed to isolate the bearing assembly and gear box from the surroundings thereby to prevent leakage of lubricant from, and ingress of dust and water drops from the outside into, the two components.
