See full text

A double-valve mechanism and a pneumatic tool including the same are provided. The double-valve mechanism is mounted in a main body of the pneumatic tool. The main body has an exhausting passage and an outlet passage communicating therewith, and an entrance passage and an inlet passage communicating therewith. The double-valve mechanism is operable from outside of the main body to move relative to the main body so as to selectively seal an entry of the inlet passage and an exit of the outlet passage. Whereby, the stop of the tool is effectively ensured after the double-valve mechanism is closed, no gas leakage will occurs, the waste of pressurized air energy and defects of the tool will be avoided, and the rotation of the rotor can be quickly stopped.
