摘要： A hand-held power tool powered by a gas combustion mechanism comprising a combustion chamber, a second chamber within a cylinder having aft and fore ends. The combustion chamber in fluid communication with the second chamber, and a first supercharger including a driver assembly, a drive motor and a fan assembly, the driver assembly having a piston and driver movable within the cylinder between said aft and fore ends. In use, whilst the piston is at or near the fore end of the cylinder, the fan assembly introduces air into the combustion chamber and the second chamber thereby pressuring the air there within, and fuel gas is introduced into the combustion chamber from a first supply port, the air and fuel gas becoming an air/fuel gas mixture therein. The drive motor moves the piston to a position at or near the aft end thereby compressing the air/fuel gas mixture within the first combustion chamber so that it is ignites within the combustion chamber to impart motion onto the piston. A second supercharger is connected to the combustion chamber for supplying a fuel gas and air mixture from a second supply port.
