Abstract
A vehicle exhaust orientation assembly directs an extremely hot, forceful haust gas flow from a tank or other vehicle that is towing a trailer or the like. The assembly has a transition shroud affixed to the exterior of the vehicle over its exhaust portal. A drum is rotatably connected to the shroud by rollers on the drum which engage a track on the shroud. Several anchoring structures are mounted on the shroud about the drum. The structures can hold the drum in one of several rotational positions of the drum on the shroud. Flow directing fins in the drum are pivoted by a linkage which can engage a tab on the drum so as to lock the fins in a selected pivot position. Rotational force is imparted to the drum and fins by flanges obliquely attached to the fins so that the fins are spun by the exhaust flow from the tank.
