Sealing configuration for an automatic tube weapon, and a tool for installation and removal

摘要

The invention relates to a sealing configuration for an automatic tube weapon, especially for firing ammunition with a non-metallic casing, as well as a tool for installation and removal of the sealing configuration. The sealing configuration (18) according to the invention, whose life and sealing effects are improved over those of conventional sealing configurations, consists essentially of an annular housing (20), an annular spring (24) which surrounds the housing (20), and a sealing packet (38) which consists of a plurality of concentrically arranged sealing rings. When a shot is fired, the annular spring (24) is acted on radially by the gas pressure through radial holes (50) in the housing (20), and the sealing packet (38) is acted on both axially and radially, via gas ducts (52) in the housing (20). Using the tool according to the invention, tilt-free simple installation and removal of the sealing configuration (18) according to the invention are possible without any additional tool. <IMAGE>
