Patent number: 9272407Abstract: A percussion tool has a cooling air channel for guiding a cooling air flow from a cooling air fan to an outside wall of a cylinder of an internal combustion engine. The cooling air channel is tapered to the extent that partial cooling air flows guided between the respective cooling fins are branched off the main cooling air flow. In such a way, the flow rate of the cooling air flow in the cooling air channel remains substantially constant, resulting in optimized engine cooling. The cooling air channel may be divided into two cooling air channels downstream of the cylinder. One of the cooling air channels guides cooling air to an exhaust gas system of the internal combustion engine, while the other cooling air channel guides cooling air to an outside wall of the guide housing of a hammer mechanism.Type: GrantFiled: January 13, 2011Date of Patent: March 1, 2016Assignee: Wacker Neuson Produktion GmbH & Co.

Patent number: 9254559Abstract: The invention relates to a percussion tool having an internal combustion engine and a hammer mechanism that can be driven by the internal combustion engine by means of a transmission. A part of the engine housing, the transmission housing, or the impact hammer mechanism housing is enclosed by a cover. The cover is spaced at a distance from the remainder of the machine, so that a gap is present between the cover and the remainder of the machine. Cooling air can flow into the gap at the lower face of the cover and flow back out via a flue and an opening. The components beneath the cover are thereby effectively cooled, even without an additional cooling air blower.Type: GrantFiled: January 13, 2011Date of Patent: February 9, 2016Assignee: Wacker Neuson Produktion GmbH & Co.
