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 spark is shot between an ignition point of an ignition plug and an ignition ground. The spark is shot from an acute corner of a core of the ignition plug. A tip end of the core has an acute angle of not more than 45 degrees. With this arrangement, an emitting point of the spark can be concentrated to the tip end of the core. In order to reduce a thermal capacity of the ignition ground so as to enhance ignitability, a side opposite to the spark seating face of the ignition ground is tapered to provide an angle. Further, the ignition ground has an apex end providing an angle which is not more than 45 degrees. Because of the apex portion, thermal capacity of the ignition ground can be reduced and an acute angle can be realized to concentrate spark receiving point at the apex portion. As a result, ignitability can be enhanced.

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： A free piston engine is configured with a pair of opposed engine cylinders located on opposite sides of a fluid pumping assembly. An inner piston assembly includes a pair of inner pistons, one each operatively located in a respective one of the engine cylinders, with a push rod connected between the inner pistons. The push rod extends through an inner pumping chamber in the fluid pumping assembly and forms a fluid plunger within this chamber. An outer piston assembly includes a pair of outer pistons, one each operatively located in a respective one of the engine cylinders, with at least one pull rod connected between the outer pistons. The pull rod extends through an outer pumping chamber in the fluid pumping assembly and forms a fluid plunger within this chamber. The movement of the inner and outer piston assemblies during engine operation will cause the fluid plungers to pump fluid from a low pressure container into a high pressure chamber as a means of storing the energy output from the engine. Alternatively, the piston assemblies may drive a linear alternator. Piston guide posts are fixed and guide the outer pistons as they reciprocate within the engine cylinders.
