  • Patent number: 7762443
    Abstract: When gas is explosively burnt within a combustion chamber, a striking piston is impulsively driven to drive out a fastener from a nose portion. A gas tube is provided between the combustion chamber and a feed cylinder which accommodates a feed piston that reciprocally moves a feed claw 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 having a restriction hole is disposed on the way of the gas tube so as to be opened and closed. The check valve 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.

  • Patent number: 7530458
    Abstract: The object of the invention is to make it possible to fill connecting fasteners of various thicknesses in a single kind of fastener magazine. A connecting fastener is such that the thickness of a connecting band (13a, 13b) is increased or decreased according to the stem diameter of a screw (12a, 12b), whereby the width of the connecting fastener (11a, 11b) as seen in the direction of travel thereof is made constant, and the connecting band (13a, 13b) is brought into engagement with a longitudinal guide groove (5a) formed in the fastener passageway of the fastener magazine (5) of a screw fastening machine. This makes it possible to stably hold the connecting fasteners (11a, 11b) of various stem diameters at a given height, thus improving the versatility of the fastener magazine.

  • Publication number: 20090071999
    Abstract: 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.
