    • A projectile launching device includes a barrel with a bore through the barrel, and a feed mechanism, moveable between a first position and a second position, with a chamber to hold a projectile, positioned at the breach end of the barrel. The chamber is not aligned with the barrel in the first position and the chamber is aligned with the barrel in the second position to facilitate firing the projectile from the chamber through the barrel. The feed mechanism is positioned to create a gap between the barrel and the feed mechanism in at least the second position. The projectile launching device also includes a sleeve adapted to forcibly slide into a position in contact with the feed mechanism, in response to gas pressure created in firing the projectile from the chamber through the barrel, to seal the gap between the barrel and the feed mechanism.
    • 射弹发射装置包括具有穿过筒体的孔的筒体,以及可在第一位置和第二位置之间移动的进给机构,其具有容纳放置在枪管的突破端处的抛射体的腔室。 腔室在第一位置不与枪管对准,并且腔室在第二位置与枪管对准,以便射弹从腔室通过镜筒射出。 进给机构定位成在至少第二位置中在筒和进给机构之间产生间隙。 射弹发射装置还包括适于强制地滑入到与进给机构接触的位置的套筒,以响应于通过枪管将射弹从腔室射出而产生的气压,以密封枪管和进给机构之间的间隙 。
