摘要:
A recoil assembly for a rifle includes a barrel assembly, a bolt, bolt actuator, and a buffer assembly. The barrel assembly includes a barrel secured to a barrel extension. The barrel assembly is configured to be movably received through the fore end of the upper receiver and to move axially relative to the upper receiver when the rifle is fired. The barrel extension is coupled to a hydraulic buffer assembly located below the barrel extension and counteracts recoil forces acting on the barrel extension when the rifle is fired. An op-rod spring is coupled to an op rod extending from a gas piston assembly on the barrel. The op-rod spring counteracts recoil forces acting the bolt actuator when the rifle is fired.

The invention relates to a mass-lockable breech mechanism (1) for a weapon, with a breech part (3) that can be mounted movably in a breech casing (2) of a corresponding weapon and with an elastic closing element (12). In order that such a breech mechanism (1) has a high degree of functional reliability and in order to ensure that the firing of high-performance ammunition does not involve any significant increase in weight of the corresponding weapon, the invention proposes integrating the closing element (12) in the breech part (3). A hydraulic transmission, connected in series with the closing element (12) and likewise arranged in the breech part (3), achieves the effect here that the closing element (12) can be made very short and that the spring characteristic can have a gradually rising increase in force.

The invention relates to a weapon recoil system (3) for a weapon barrel (2) axially displaceable in the weapon housing (6), the system consisting of at least a pressure vessel (4) and a pressure cylinder (5) with a pressure piston (11). The weapon barrel end is connected to the pressure piston (11) for compressing a gas cushion in the pressure cylinder (5), and in its middle region is connected to an annular piston (13) having through-flow channels. A sleeve (17) operable by means of springs (8) closes these channels when the weapon barrel (2) is idle and during forward movement of the barrel. During recoil of the barrel, said sleeve (17) is displaced by the flowing fluid and hence the channels are opened. The pressure piston (11) is configured so that during recoil of the barrel a large cross-section is open for the liquid to flow, whereby a relatively low back pressure occurs, whereas during forward movement of the barrel only a small cross-section is open, so that a large back pressure occurs. A relatively simple recoil construction is therefore produced in the hydraulic recoil braking means, without the previously necessary control devices, wherein the weapon barrel (2) is supported on the pressurised gas cushion in the pressure cylinder (5).

In a ball mounting, especially for fitting in armoured glass panes (1), with a ball-type housing (2), a ball (3) rotatably fitted in the spherical hollow (6) of the housing (2) and an attachment secured to the ball (3) for a hand firearm, in which the ball (3) and the attachment have an aligned bore through which the shots (31) fired from the weapon may pass, the stress on the pane (1) is reduced in that the attachment is flexibly spring-mounted so as to be longitudinally movable. The ball mounting may therefore also be used in a pane (1) which has been shot-damaged on the outside, without being torn from its securing system.

L'invention a pour objet un dispositif de tir (1) pour une munition (2) de défense rapprochée, munition comportant un étui rigide (6) renfermant au moins un projectile (7), étui solidaire d'un culot (8) solidarisable par un moyen de liaison à une embase (3) du dispositif de tir comportant des moyens de mise à feu de la munition. Ce dispositif (1) est caractérisé en ce qu'il comporte un tube (10) coiffant la munition (2) après fixation de cette dernière sur l'embase (3), tube pouvant être lui-même rendu solidaire de l'embase par un moyen d'attache (11), tube portant par ailleurs un bipied (15) articulé permettant l'orientation en site du dispositif (1).
