Abstract: A mortar includes at least one barrel mounted movably over a ball journal in a bottom supporting device, and an aiming device serving to aim the barrel vertically and horizontally. In order to be able to aim the barrel of the mortar automatically in a simple and cost advantageous manner, the aiming device preferably comprises a carriage that can be moved along guideways essentially horizontally towards or away from the barrel. At the carriage, the first end region of a pivoted arm is mounted so that it can be rotated about a pivot axis, and the second end region of the pivoted arm is connected with a spherical plain bearing, guiding the barrel. The spherical plain bearing embraces a housing part, which is open at its end faces and in which an inner part is mounted spherically (rotatably), which contains a cylindrical barrel guide, for movably accommodating the barrel.

Abstract: The invention relates to a weapon (1), constructed relatively simply and compactly, for shooting ammunition (2), with a barrel (3) with recoil and a braking device (12) damping the barrel recoil. According to the invention, a plastically deformable absorption body (12) is used as the braking device (12) for reducing the recoil energy. Thus, a weapon assembly for firing ammunition is provided, wherein the weapon assembly includes: (a) a weapon including a weapon barrel provided with a recoil spring that holds the weapon barrel in an initial position; and (b) a braking device that damps barrel recoil of the weapon barrel when firing ammunition, wherein the braking device is a plastically deformable absorption body.

Abstract: The invention relates to a hydropneumatic braking and return system for barrel-recoil guns having at least one working cylinder (1) which can be arranged between the gun barrel (6) of the gun and that mass (7) of the gun which does not recoil, contains a brake fluid (4) and has displaceable working pistons (3) which are arranged on a piston rod (2). In order to obtain a braking and return system of simple construction for barrel-recoil guns, with which it is simply possible, moreover, to take changes in different shooting parameters into consideration, the invention proposes to replace the braking cylinder of known systems with a simple working cylinder (1) having a working piston (3), wherein the working cylinder (1) is connected to a hydraulic accumulator (9) via a separate controllable pressure relief valve (10), wherein the pressure relief valve (10) can preferably be actuated in such a way that a substantially constant brake-force profile results during the recoil of the corresponding gun barrel (6).
