ABSTRACT:
An air cooled internal combustion engine for a hand-held power tool has a flywheel fan that is rotated within a fan housing. The bottom of the fan housing, which is perpendicular to the axis of rotation of the fan, includes an opening for an air duct. Ramps axe formed around the leading edges of the duct opening, either on a plate (metal or plastic) attached to the housing or integrally with the bottom wall, for deflecting solid particles entrained in the air away from the outlet. A relatively particle-free stream of pressurized air stream is diverted into the duct and delivered to an air intake box containing an air filter and carburetor.
