    • In an explosive charge driven setting gun a breech block is located in the rear of the gun housing and the gun barrel is axially displaceable within the gun housing. A firing projection is formed on the rear end of the barrel so that a propellant charge supported on the breech block can be fired by displacing the barrel rearwardly against the breech block. The displacement force can be provided by a spring which biases the barrel rearwardly. A latch can be mounted in the housing for securing the barrel in a forward position and when the latch is released, the barrel can be displaced rearwardly against the breech block.
    • 在爆炸电荷驱动设置枪中,后枪块位于枪壳的后部,枪筒在枪壳内可轴向移动。 在枪管的后端形成一个击球突起,这样一来,支撑在后膛块上的推进剂装料可以通过将镜筒向后移动抵挡后枪块来发射。 位移力可以由向后偏压筒的弹簧提供。 闩锁可以安装在壳体中,用于将枪管固定在向前的位置,并且当闩锁被释放时,枪管可以向后移动抵靠后膛块。

    • The invention relates to a hand-held machine tool (1) for setting a nail (2), having a safety mechanism (10) which can be actuated by a user and a button (11) which can be actuated to trigger a setting of the nail (2). A mixture of flammable gas and air can be ignited in a combustion chamber (4). A piston (6) is movably arranged in the combustion chamber (4) in order to be accelerated in the setting direction (3) by the combustion gases. There is a stamp (7) on the piston (6) for driving the nail (2). A compressor (17) for compressing the air in the combustion chamber (4) is directly connected to the combustion chamber (4) via a channel (20). A valve (22, 23) which connects the channel (20) or the combustion chamber (4) to the environment is opened between the actuating of the safety mechanism (10) and the actuating of the button (11).

    • A tool for driving a nail or other fastener is actuated by a caseless propellant charge (62) formed of combustible material that is transported into a combustion chamber (44) on a strip (64). The propellant charge (62) is ignited by striking a sensitizer portion (90) of the charge at an oblique angle. The ignition member (66) intermixes the sensitizer material (90) with an oxidizer layer (88) of the surface of the propellant charge (62), resulting in combustion of the charge. When ignited, the propellant charge (62) is compressingly interposed between an orifice plate (74) and a movable portion (80) of the combustion chamber. The orifice plate (74) includes a pedestal (78) with an annular compression surface that separates the surface of the ignition area from the remaining surfaces of the charge (62); insuring that ignition gases are forced through the charge (62). An annular C-shaped ring (82) is interposed between the orifice plate (74) and the movable portion (80) of the combustion chamber (44). When the charge (62) is ignited, the resulting gas pressure resiliently expands the annular C-shaped ring (82) and urges opposite axial ends of the C-shaped ring (82) into sealing relationship between the relatively movable components of the combustion chamber. Combustion gases are communicated through orifices (76) in the orifice plate (74) to a cylinder (40) where the gases force movement of a driver (42), which driver strikes and drives a fastener such as a nail. The driver (42) is reciprocally movable within the cylinder (40) and is returned to its precombustion position by a gas spring return cylinder (17). The gas return cylinder (17) is mechanically interconnected to the driver (42) and contains a sealed gaseous fluid that is independent of and segregated from fluids in the combustion chamber (44). An assembly (60) for deaccelerating the driver includes a series of spaced and aligned progressively sized metal cup members (110, 112, 114) of progressively increasing mass, contact surface area and interface angles.
    • 用于驱动钉子或其他紧固件的工具由被输送到条带(64)上的燃烧室(44)中的可燃材料形成的无壳推进剂装料(62)致动。 通过以斜角撞击电荷的敏化剂部分(90)来点燃推进剂装料(62)。 点火构件(66)将敏化剂材料(90)与推进剂装料(62)的表面的氧化剂层(88)混合,导致电荷的燃烧。 当点燃时,推进剂装料(62)被压缩插入在燃烧室的孔板(74)和可动部分(80)之间。 孔板(74)包括具有环形压缩表面的基座(78),所述环形压缩表面将点火区域的表面与电荷(62)的其余表面分离; 确保点燃气体被迫通过电荷(62)。 环形C形环(82)介于孔板(74)和燃烧室(44)的可动部分(80)之间。 当充电(62)被点燃时,所产生的气体压力使环形C形环(82)弹性地膨胀,并且将C形环(82)的相对的轴向端推到燃烧室的相对可动部件之间的密封关系 。 燃烧气体通过孔板(74)中的孔口(76)传递到气缸(40),气缸迫使驱动器(42)的驱动器撞击并驱动诸如钉子的紧固件的驱动器(42)的运动。 驱动器(42)可在气缸(40)内往复运动,并通过气弹簧复位缸(17)返回到其预燃位置。 气体回收缸(17)机械地互连到驱动器(42)并且包含与燃烧室(44)中的流体无关并与其分离的密封的气态流体。 用于对驱动器进行减速的组件(60)包括逐渐增加的质量,接触表面面积和界面角度的一系列间隔和对准的渐进尺寸的金属杯构件(110,112,114)。
