    • A pyrotechnic actuator for a power cutting tool is disclosed. The pyrotechnic actuator comprises a housing defining a cavity therein, a piston positioned at least partially within the cavity, and an insert-molded unitary assembly positioned within the cavity. The unitary assembly comprises a piston engagement member and a base. A sealed void is defined intermediate the piston engagement member and the base. The unitary assembly comprises a breakable member extending intermediate the piston engagement member and the base and a pyrotechnic initiator positioned at least partially within the base. The pyrotechnic initiator, upon application of a current pulse thereto, is configured to generate a pressurized gas in the sealed void that exerts a force on the piston engagement member and breaks the breakable member thereby causing the piston engagement member and the piston to move relative to the base and the housing.
    • 公开了一种用于动力切割工具的烟火致动器。 烟火致动器包括在其中限定空腔的壳体,至少部分地定位在空腔内的活塞,以及定位在空腔内的嵌入成型的整体式组件。 整体组件包括活塞接合构件和基座。 在活塞接合构件和基座之间限定了密封空隙。 整体组件包括在活塞接合构件和基座之间延伸的可破坏构件和至少部分地位于基座内的烟火引发器。 烟火引发器在施加电流脉冲时被配置为在密封空腔中产生加压气体,该加压气体在活塞接合构件上施加力并破坏可破坏构件,从而使活塞接合构件和活塞相对于 基地和住房。

    • A quick-loosening mechanical linking device that includes housing, a release cavity having a predetermined height, a bolt, and an actuator. The bolt is disposed within the housing and includes an attachment means projecting out from the housing, a release zone such as an intended failure zone, and a head with a piston face. Upon actuation of the actuator, the bolt deforms and/or fails at the release zone and the attachment means moves farther out from the housing by a distance equal to the height of the release cavity. The release cavity preferably includes an abutment formed at its bottom, and the actuator is preferably an electric initiator having a pyrotechnic charge.
    • 一种快速松动的机械连接装置,包括壳体,具有预定高度的释放空腔,螺栓和致动器。 螺栓设置在壳体内,并且包括从壳体伸出的附接装置,诸如预期故障区域的释放区域和具有活塞面的头部。 在致动器致动时,螺栓在释放区域处变形和/或失效,并且附接装置从外壳移动距离等于释放腔的高度的距离。 释放腔优选地包括在其底部形成的邻接部,并且致动器优选地是具有烟火充电的电引发器。
