Power tool

A power tool comprising:

• an internal combustion engine comprising a cylinder;
• an injection valve supplying fuel to the internal combustion engine;
• a fuel tank embodied completely separate from the injection valve;
• a fuel pump conveying fuel from the fuel tank to the injection valve, the fuel pump embodied separate from the injection valve;
• a fan wheel driven by the internal combustion engine;
• wherein the cylinder is arranged in a first cooling zone of the power tool and wherein the fan wheel conveys cooling air through the first cooling zone;
• wherein the fuel pump is arranged in a second cooling zone of the power tool;
• wherein between the first cooling zone and the second cooling zone a buffer zone is arranged, wherein the buffer zone is separated by at least one first partition wall from the first cooling zone and by at least one second partition wall from the second cooling zone;
• wherein the fuel pump is arranged on the fuel tank;
• wherein the fuel tank is separated from the internal combustion engine by a vibration gap, wherein the vibration gap allows for relative movement of the fuel tank relative to the internal combustion engine;
• wherein the fuel pump is positioned remote from the cylinder of the internal combustion engine and is separated from the cylinder by the vibration gap so that the fuel pump is arranged spatially separated from the cylinder and an excessive heating of the fuel pump is prevented.

• wherein between the first cooling zone and the second cooling zone a buffer zone is arranged, wherein the buffer zone is separated by at least one first partition wall from the first cooling zone and by at least one second partition wall from the second cooling zone;
• wherein the second cooling zone is positioned in a flow path of combustion air sucked in by the internal combustion engine through an intake opening of the power tool, wherein the combustion air flows in from the environment through the intake opening into the second cooling zone and from the second cooling zone to the internal combustion engine and acts as cooling air in the second cooling zone;
• wherein the fuel pump is arranged in a flow path of the combustion air that is flowing in through the intake opening and the fuel pump is directly cooled by the combustion air flowing in from the environment into the second cooling zone.
