Abstract
A cooling air blower for a combustion engine for a two-stroke engine of a hand-held working tool has a cooling air channel for supplying cooling air to a combustion engine and a blower fan for conveying air into the cooling air channel. A combustion air channel branches off the cooling air channel for guiding combustion air to an intake member of the combustion engine. The combustion air channel has a section extending adjacent to the cooling air channel. The combustion air channel has furthermore an air intake socket within that section, the air intake socket being narrower than the cooling air channel and extending transverse, when viewed in a plan view, to a main air flow direction of the cooling air channel into the cooling air channel. The air intake socket is positioned at a slant relative to the main air flow direction and has an inlet opening located on a side of the intake socket facing away from the blower fan. The inlet opening allows passage of air from the cooling air channel into the combustion air channel.
