    • A caging plunger engages a notch in the gyro gimbal to cage the rotor in the null roll and pitch positions. A latching plunger holds the caging plunger in position against the uncaging spring by use of a tight friction fit of the latching plunger in its bore. When the gyro is fired, spinup gas pressure directed between the caging plunger and the latching plunger displaces the latching plunger while holding the caging plunger in position against the uncaging spring. After spinup, the pressure between the plungers decreases to allow the uncaging spring to retract the caging plunger, thus uncaging the gyro rotor.
    • 笼式柱塞接合陀螺仪万向架中的凹口,以将转子保持在空辊和俯仰位置。 闩锁柱塞通过使用闩锁柱塞在其孔中的紧密摩擦配合将保持柱塞保持在适当的位置。 当陀螺仪被点燃时,引导在笼状柱塞和闩锁柱塞之间的分离气体压力使闩锁柱塞移动,同时将定位柱塞保持在与防松弹簧相对的位置上。 在旋转之后,柱塞之间的压力减小,以允许开闭弹簧缩回笼式柱塞,从而使陀螺仪转子脱钩。
