Arrangement related to a motor-driven tool
First Claim
1. An arrangement for cleaning of intake air for an air-cooled internal combustion engine, the arrangement comprising:
- an air conductor surrounding a fan wheel, an inner wall of the air conductor being arranged for guiding air propelled by the fan wheel;
an air nozzle for cleaning of the intake air, arranged on the inner wall of the air conductor radially close to said fan wheel, the air nozzle serving as a passage way for providing cleaned intake air from the fan wheel to the engine;
wherein the air nozzle and the air conductor are manufactured in one piece; and
,wherein the air nozzle has a first wall and a second wall extending substantially perpendicular to the inner wall of the air conductor, the first wall being arranged between the fan wheel and the second wall, the second wall having an end part proximate an inlet of the nozzle, wherein the end part is directed towards the fan wheel.

Abstract
An arrangement for cleaning of intake air for an air-cooled internal combustion engine of a motor-driven tool, such as a chain saw. The arrangement includes an air conductor surrounding a fan wheel arranged to propel intake air around an axis of the fan wheel. An inner wall of the air conductor is arranged for guiding air propelled by the fan wheel. An air nozzle for cleaning of intake air is arranged on the inner wall of the air conductor radially close to said fan wheel. The air nozzle serves as a passage way for providing cleaned intake air from the fan wheel to the engine of the motor-driven tool, wherein the air nozzle and the air conductor are manufactured in one piece.
