ABSTRACT:
A breech mechanism for large caliber artillery pieces is characterized by a specifically designed sealing function in the form of an intermediate layer between a main portion of the breech mechanism and a seating portion displaceable in relation thereto by the gas pressure in the gun. The seating portion, on being displaced towards the breech, compresses the intermediate layer disposed therebetween and consisting of an elastically deformable refractory material which, on its deformation, is urged into tight abutment against the rear portion of the gun barrel about the loading space of the gun along a gap between the seating portion and the main portion of the breech mechanism.
