摘要： A combustion-type power tool includes a cylinder and a combustion chamber frame disposed to surround the cylinder and movable along the cylinder. A partition wall divides an inner space of an outer frame into a first space in which the cylinder and the combustion chamber frame are disposed and a second space in which a gas cartridge cylinder is disposed and has a through-hole through which the first space and the second space are in fluid communication with each other. A plurality of ribs is formed on an outer surface of the cylinder for regulating an exhaust gas flow generated by combustion of a gaseous mixture in the combustion chamber. The ribs enable exhaust gas discharged from the combustion chamber to be directed away from the through-hole, thereby enabling the gas cartridge cylinder to be maintained at a substantially constant temperature.
