ARTILLERY GUN Russian patent published in 2007 - IPC F41F1/00 

FIELD: pyrotechnical units, in particular, self-propelled tube artillery guns provided with systems of automatic formation of powder charges in the conditions of operating functioning.

SUBSTANCE: the artillery gum operating on a batched grained propellant has a barrel with an assembly for side input of the grained powder charge located above the chamber, cradle, system of automatic formation of charges with a flexible worm hose a distant conveying of grained powder mass, and a mechanism for joining the end of the worm hose to the end of the assembly for side input of the charge to the chamber. The joining mechanism is made of three components: a receiver fastened on the cradle, and two flexible hoses with rigid pipe connections for formation of a telescope joint. The pipe connections in the telescope joint are mutually spring-loaded for reduction of the length of the telescope section. The cradle receiver is made for formation of a sliding spring-loaded contact with the end of the assembly for side input of the charge, and the inner duct in the joining mechanism over the entire length from the end of the worm hose to the end of the assembly for side input of the charge has a permanent slope for natural flow of the grained mass.

EFFECT: provided serviceability of the system of automatic formation of charges in the condition of a considerable mobility of the artillery gum barrel both during a short and the process of preparation to it.
