摘要： A powered nailer includes a power source including a driving element reciprocating within a cylinder between a prefiring position and a fastener driving position, the latter occurring when the driving element engages a bumper disposed at the bottom of the cylinder. A reciprocating valve element defines a combustion chamber in fluid communication with the cylinder, and is configured for receiving a dose of fuel and air prior to a user-generated ignition. A return chamber at least partially surrounds the cylinder and is in fluid communication with the cylinder, being configured for receiving a supply of pressurized air generated by the driving element as it moves from the prefiring position to the fastener driving position, the pressurized air acting on an underside of the driving element for returning it to the pre-firing position.

摘要： A fastener-driving tool includes a housing and a workpiece-contacting element movable between a rest position and an activated position. The tool also includes a trigger connected to the housing and movable between a rest position and an activated position, a control valve including an actuating pin, an actuation lever movably connected to the trigger and movable between a rest position and an actuating position adjacent to the actuating pin, and a trigger control mechanism associated with the actuation lever and configured for moving and holding the actuation lever in the actuating position. In a powered mode, the trigger control mechanism causes the-actuation lever to move and remain in the actuating position such that the tool is actuated each time the workpiece-contacting element contacts a workpiece and moves to the activated position causing the actuation lever to contact the actuating pin and initiate an actuation of the tool.

摘要： A combustion-powered fastener-driving tool includes a combustion-powered power source having a combustion chamber, a reciprocating piston and driver blade, and a valve sleeve reciprocable relative to the power source between a rest position and a firing position. The valve sleeve partially defines the combustion chamber. A lockout device is in fluid communication with the combustion power source and includes a reciprocating gas piston connected to a latch in operational proximity to the valve sleeve. The lockout device is configured such that upon combustion in the combustion chamber, gas from the combustion engages the gas piston and moves the latch to an engaged position in which the valve sleeve is prevented from moving to the rest position.
