Abstract:
In combination with an air cooled internal combustion engine having a radiator intake including an engine driven rotary suction fan shaft and fan blades thereon, and an intake radiator housing in front of said fan and having a front ingress and a rear exit, said ingress permitting flow of an air stream through said radiator housing under the influence of said suction fan, the improvement which comprises:a. a generally frustoconical body having an enlarged diameter inner end mounted adjacent said radiator housing in alignment with said ingress, and also having a reduced diameter outer end;b. a generally frustoconical body mount part on which said body is mounted for rotation about an axis;c. said body being made up of substantially axially extending deflector fins extending outwardly in convergent relationship and spaced peripherally apart to provide elongate air entrance slits between them; andd. mechanism for driving said body in rotation to deflect particles seeking to enter said slits away from said slits without materially decreasing the rate of air flow created by said suction fan.
