摘要： A combustion-type power tool having a cooling arrangement for cooling a gas canister. The tool includes a housing having a gas canister accommodating section in which a gas canister is accommodated. An air passage is defined between the gas canister accommodating section and the gas canister accommodated therein. The gas canister accommodating section is formed with an air inlet port in communication with the air passage for introducing air into the air passage. Since air flows along the gas canister, the gas canister can be cooled. If the tool is provided with a fan, the rotation of the fan causes air suction passing through the air passage.

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 combustion chamber is formed on top of the cylinder that accommodates a gaseous mixture of existing air in the combustion chamber and fuel injected therein from a gas cylinder. A spark plug generates a spark to combust the gaseous mixture in the combustion chamber. A trigger switch produces the spark in the spark plug when operated. A piston slidably moves along the inner surface of the cylinder and driven by combustion in the combustion chamber. A driving blade is secured to the piston for driving a fastener. A partition wall divides the inner space of the outer frame into a first space in which the cylinder and the combustion chamber frame are disposed and a second space in which the gas cylinder is disposed. The partition wall is formed with 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 the outer surface of the cylinder for regulating an exhaust gas flow generated by combustion of the gaseous mixture in the combustion chamber. With the ribs, the exhaust gas discharged from the combustion chamber is not directed toward the through-hole, thereby preventing the gas container from heating up.
摘要翻译：一种燃烧式电动工具包括一个气缸和一个燃烧室框架，该燃烧室框架设置成围绕气缸并沿气缸移动。燃烧室形成在气缸的顶部，其容纳燃烧室中的现有空气的气体混合物和从气瓶注入的燃料。火花塞产生火花以燃烧燃烧室中的气体混合物。触发开关在操作时产生火花塞中的火花。活塞沿着气缸的内表面滑动地移动，并通过燃烧室中的燃烧而驱动。驱动叶片固定在活塞上用于驱动紧固件。分隔壁将外框架的内部空间划分成其中设置有气缸和燃烧室框架的第一空间和设置气瓶的第二空间。分隔壁形成有通孔，第一空间和第二空间通过该通孔彼此流体连通。在气缸的外表面上形成多个肋，用于调节由燃烧室中的气体混合物的燃烧产生的废气流。利用肋，从燃烧室排出的废气不指向通孔，从而防止气体容器升温。

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.

The peripheral wall is formed with an exhaust hole at a first axial position. A piston is reciprocally movable in an axial direction and is slidable in contact with the inner peripheral surface. A combustion-chamber frame is abuttable on a head portion to provide a combustion chamber in cooperation with the head portion and the piston. The piston allows the combustion chamber to be in fluid communication with an atmosphere through an upper space above the piston and through the exhaust hole when the piston is located at a bottom dead center. The fin is disposed at the outer peripheral surface and has a portion extending in a direction slanted in relation to the axial direction and oriented toward the exhaust hole.
