摘要
The invention relates to an exhaust silencer for internal combustion engines, particularly for manually operated appliances, in which a reduction of the contact and exhaust gas temperatures in order to prevent fire risks on contact with easily flammable objects, particularly forest fires, during the putting into operation of the manually operated appliance and with the supply of a large quantity of fresh air compared with the quantity of exhaust gas in order to bring about a maximum cooling of the hottest gases and/or the outer walls, is achieved in that the wall of the exhaust silencer shell portion which bounds the cooling pipe on one side, following the final outlet hood facing the pipe output port for deflecting the exhaust gas has a negative angular variation with an angle of approximately 2 to 8 for forming a pure or fluidic logic element.
