在射角变化大,装药号变化多,并且采用半自动炮闩的火炮上为了解决既保证小号装药大射角射击时有足够的开闩速度,又要保证在小射角大号装药射击时复进速度不过大,不破坏复进稳定性和开闩不过猛的矛盾,我们对弹簧活塞瓣式自调复进速度装置进行了探讨并在 Changes in the angle of injection, change in charge number, and the use of semi-automatic gun artillery on the gun in order to solve both the large angle shot to ensure adequate opening speed, but also to ensure that small size Repellent drug injection speed is not too large, does not undermine the stability of the forward and open the door but too fierce contradiction, we spring-loaded self-adjusting spring-piston speed device was discussed in
