Breechblock buffer for an automatic firing weapon

摘要

A breechblock buffer serves for catching the recoiling breechblock following the firing of a cartridge. This breechblock buffer comprises a buffer piston and a compressible liquid. With the heretofore known breechblock buffers there is provided a container housing a compressed gas. The invention contemplates eliminating the need for such container. Instead of a gas container there is provided a packet or set of plate springs serving as an elastic structure. Furthermore, the breechblock buffer possesses a recoil buffer device. For guiding and sealing the buffer piston, a guide ring is arranged between two sealing rings.
