Abstract
A power tool, particularly a hand-held power tool, has a striking mechanism with a striker transmitting impact energy to a tool, a drive operative for actuating the striker through an air cushion, and a heat insulating element which is associated with the striker and insulates the same from heat generated in the air cushion during the operation of the power tool. The heat insulating element may simultaneously be formed as a mechanical buffer.
