摘要： A gas combustion type driving tool is provided with two modes including: a contact mode in which a contact arm 15 is pressed against a workpiece P into which a nail is to be driven and the nail is driven under a condition that a trigger lever 16 is pulled; and a trigger mode in which the trigger lever 16 is pulled and the nail is driven under a condition that the contact arm 15 is pressed against the workpiece P. In either mode, a nail driving can be continuously executed.

摘要： A gas nailer is provided with a driving cylinder 7, a driving piston 10, a combustion chamber 8, a gas fuel cartridge 2, and a supercharging device 3. The driving piston 10 is operated in the driving cylinder 7 by a combustion pressure generated when a mixture of gas fuel and air is burned in the combustion chamber 8, and a driver hammers a fastener by an operation of the driving piston. A locking device 15 for locking the driving piston 10 is provided in the driving cylinder 7 so as not to move the driving piston 10 in accordance with a pressure increase in the combustion chamber 8 during a supercharging operation in which compressed air is supplied by the supercharging device 3.

摘要： By moving a movable sleeve 10 provided above a driving cylinder 3 in a vertical direction so as to come into contact with a cylinder head 8 above the driving cylinder 3, a combustion chamber 6 becomes a closed state. When mixed gas obtained by stirring and mixing air and fuel gas by a rotary fan 21 is ignited by a spark plug 20 so as to be burned explosively in the combustion chamber 6, high-pressure combustion gas is applied to a driving piston 4 to impulsively drive the driving piston 4 so that a driver 5 coupled to a lower surface of the driving piston 4 drives a fastener. An upper wall surface on an outer portion of the combustion chamber 6 is disposed at a position far away from the spark plug 20 so that a flow speed of the mixed gas passing the upper wall surface decreases to the extent that an ignition when the mixed gas arrives at the spark plug 20 is not interrupted. An opening groove 22 is formed in the upper wall surface so as to be opened to the combustion chamber 6.

摘要： When gas is explosively burnt within a combustion chamber 5, a striking piston is impulsively driven to drive out a fastener from a nose portion. A gas tube 26 is provided between the combustion chamber 5 and a feed cylinder 21 which accommodates a feed piston that reciprocally moves a feed claw 23 engaged with and disengaged from connected fasteners to a nail feed direction for feeding to the nose portion side and an evacuation direction in opposite thereto. A check valve 31 having a restriction hole 33 is disposed on the way of the gas tube 26 so as to be opened and closed. The check valve 31 is normally urged by a spring to a closed direction and opens against the force of the spring by the gas pressure from the combustion chamber.
