  • Publication number: 20190224830
    Abstract: A driving tool includes a main body, a trigger, a contact member and a control unit. The main body has a combustion chamber configured to be filled with fuel and compressed air. The trigger is configured to operate an ignition device to combust a mixture of the fuel and the compressed air filled in the combustion chamber. The contact member is brought into contact with a driving target member to enable an operation of the trigger. The control unit is configured to start an injection of the fuel when the contact member is turned on, and to complete an injection of the air after the trigger is turned on.

  • Publication number: 20190224831
    Abstract: A driving tool includes a combustion chamber, a cylinder, a valve and a control unit. Fuel and compressed air are supplied into the combustion chamber. The cylinder is configured to movably store a piston which is driven by combustion pressure at a time of igniting a mixture of the fuel and the compressed air filled in the combustion chamber. The valve is configured to open and close a passage through which the compressed air is supplied into the combustion chamber. The control unit is configured to control the valve to supply the compressed air into the combustion chamber when the control unit determines that a return of the piston is completed.
