ABSTRACT:
Engine cooling fan shrouding comprising a flexible shroud mounted on a stationary component within the engine compartment and a rotating shroud carried by the blade tips of an engine mounted cooling fan. With this arrangement, there is small clearance between the rotating shroud and the flexible shroud so that most of the air drawn in by the fan is through the radiator core for effective cooling of liquids circulated therein. The flexible shroud deflects without damage on engine vibration causing the rotating shroud to contact the flexible shroud.
