<p>The subject of the invention is a device to utilise the flow of ambient substances (1) such as air, water, snow, slush, dust, mud, sand, in a mobile conveyance propelled by enclosed wheels or tracks (5), wherein said flow (1) is introduced into a duct (2) past the enclosure of the wheel or track and deflected (3) from behind against the paddles, raised treads or lugs (6) of the wheel or track (5), and the centrifugal flow arising from rotation inside the spirally formed enclosure (7) is deflected (8) into the duct (2) at the front and increases the flow (1), whereby the resistance of the conveyance's propelling wheel or track is reduced.</p> |
