Patent ID: 7380526

Claim:
A power tool comprising: a working tool; a two-stroke engine driving the working tool; the two-stroke engine comprising a cylinder and a piston reciprocating within the cylinder in a direction of a longitudinal cylinder axis, wherein the cylinder has a combustion chamber delimited by the piston; the two-stroke engine comprising a crankcase and a crankshaft rotatably supported in the crankcase about an axis of rotation, wherein the piston drives with a connecting rod the crankshaft; the two-stroke engine having one or more transfer passages connecting the crankcase to the combustion chamber in at least one position of the piston, wherein the one or more transfer passages each have a transfer port opening into the combustion chamber; the two-stroke engine comprising a mixture passage with a mixture intake for supplying a fuel/air mixture to the crankcase; the two-stroke engine having an air passage for supplying combustion air; wherein the mixture passage and the air passage are connected to a clean side of an air filter of the two-stroke engine; wherein the combustion chamber has an exhaust port provided within the cylinder; wherein the two-stroke engine has a transverse plane dividing the cylinder in a direction of the longitudinal cylinder axis; wherein the exhaust port is arranged on one side of the transverse plane; and wherein the air passage and the mixture passage are arranged on opposite sides of the transverse plane; a power tool housing and a top handle that extends across a top side of the power tool housing, wherein the two-stroke engine is arranged in the power tool housing such that the transverse plane of the two-stroke engine is parallel to a longitudinal axis of the top handle.
