    • A combustion-powered fastener-driving tool (10) includes a combustion-powered power source (14), a workpiece contact element (32) reciprocable relative to the power source (14) between a rest position and a firing position, a control system (67) operationally associated with the power source, a trigger (26) connected to the control system (67) providing operator interface with the control system (67). The control system (67) is configured so that an operator may select between a sequential firing mode in which the trigger (26) must be released between firings, and a repetitive cycle mode in which the trigger is continually depressed between firings. The trigger (26) is connected to the control system (67) so that at least one of the frequency and duration of pulling of the trigger (26) converts the operating mode from the sequential mode to the repetitive cycle mode.
    • 燃烧供电的紧固件驱动工具(10)包括燃烧供电的动力源(14),在静止位置和击发位置之间相对于动力源(14)往复运动的工件接触元件(32),控制系统 (67),与所述电源操作地相关联,连接到所述控制系统(67)的触发器(26)提供与所述控制系统(67)的操作者接口。 控制系统(67)被配置为使得操作者可以在触发器(26)必须在发射之间释放的顺序点火模式和在触发器在发射之间不断地按下触发器的重复循环模式之间进行选择。 触发器(26)连接到控制系统(67),使得触发器(26)的拉动的频率和持续时间中的至少一个将操作模式从顺序模式转换到重复循环模式。

    • A combustion-powered fastener-driving tool (10) includes a combustion powered power source (14) including a cylinder (20) defining a path for a reciprocating piston (22) and an attached driver blade (24), the piston (22) reciprocating between a pre-firing position achieved prior to combustion and a bottom out position. Upon combustion in the power source (14), the cylinder (20) includes at least one exhaust valve (52) configured for releasing combustion gases from the cylinder (20). The at least one exhaust valve (52) is dimensioned so that sufficient gas is released to reduce post-combustion pressure in the cylinder (20) to approximately one atmosphere in the time available for the piston (22) to travel past the at least one exhaust valve (52) and return to the at least one exhaust valve (52).
    • 燃烧供电的紧固件驱动工具(10)包括燃烧供电的动力源(14),其包括限定往复活塞(22)的路径的气缸(20)和附接的驱动器叶片(24),所述活塞(22) 在燃烧前实现的预发射位置与底部向外位置之间往复运动。 在所述动力源(14)中燃烧时,所述气缸(20)包括至少一个排气阀(52),所述排气阀构造用于从所述气缸(20)释放燃烧气体。 所述至少一个排气阀(52)的尺寸被设计成使得足够的气体被释放以将活塞(22)穿过所述至少一个的所述时间内的气缸(20)中的后燃烧压力降低到大约一个大气压 排气阀(52)并返回到至少一个排气阀(52)。
