摘要： A suppressed pistol has a breech block and a slide mounted on a frame. The breech block and slide are separate pieces, movable relatively to one another and the frame. A link extends between the breech block and the frame. The link carries a cam and a cam follower. The cam follower on the link engages a cam on the frame, the cam on the link engages a cam follower on the slide. Action between the cams, cam followers and the link causes separation between the breech block and the slide during operation of the pistol. The suppressor includes a container having baffle plates with truncated cones defining openings offset from the geometric centers of the baffle plates.

摘要： A fixed-barrel, gas-operated firearm having its barrel concentrically mounted within a pressure tube enclosing substantially all of the moving parts of the firearm's action. A gas cup reciprocates under the influence of propellant gas pressure when the firearm is fired, driving slide members that link the pressure cup to the firearm's bolt rearward within the pressure tube, unlocking the breech, rotating and retracting the bolt, discharging the spent cartridge casing and then advancing the bolt to chamber a new cartridge.

摘要： Firearms having a locked breech are disclosed. An example firearm includes a barrel; a bolt head; a firing pin having a bulge; a bolt head carrier having a forward position and a rearward position; a central force receiving component receiving a rear end of the barrel and defining a plurality of recesses; and a locking bolt penetrating the bolt head. The locking bolt is movable between: (1) a locked position wherein the locking bolt engages in the recesses of the central force receiving component to thereby lock the bolt head to the central force receiving component and (2) an unlocked position wherein the bolt head is free to move with the bolt head carrier. The locking bolt is pressed by the bolt head carrier into the locked position when the bolt head carrier is in the distal position. The locking bolt defines an oblong hole which is penetrated by the firing pin. The oblong hole has a beveled edge which engages the bulge of the firing pin to push the firing pin rearward when the locking bolt moves from the locked position to the unlocked position. The barrel defines a gas intake opening. A gas cylinder is located in the central force receiving component. The gas cylinder is in communication with the gas intake opening. The bolt head carrier forms at least a portion of a gas piston which cooperates with the gas cylinder.
摘要翻译：公开了具有锁定的后膛的火器。一个示例枪支包括一个桶; 螺栓头; 具有凸起的撞针; 具有前进位置和后方位置的螺栓头托架; 中央力接收部件，其容纳所述筒体的后端并限定多个凹部; 以及穿过螺栓头的锁定螺栓。锁定螺栓可以在以下位置之间移动：（1）锁定位置，其中锁定螺栓接合在中心力接收部件的凹部中，从而将螺栓头锁定到中心受力部件，以及（2）解锁位置，其中螺栓头可以用螺栓头托架自由移动。当螺栓头托架处于远端位置时，锁定螺栓被螺栓头托架压入锁定位置。锁定螺栓限定了由撞针穿透的长孔。该长方形孔具有斜边缘，当接合螺栓从锁定位置移动到解锁位置时，接合推杆的凸起的部分向后推动撞针。枪管限定了进气口。气瓶位于中央力接收部件中。气瓶与进气口连通。螺栓头托架形成与气瓶配合的气体活塞的至少一部分。

摘要： A breech lock mechanism for automatic firearms, in particular, a rigidly closing breech lock mechanism with loosely located support flaps in its breech head which will slide along an associated and complementary formed latching and unlatching component into its rearward latching position during the opening of the breech lock mechanism. The surfaces of the support flaps which face towards the latching and unlatching component are at least partly provided with a lubricating layer whose hardness is different with respect to the complementary latching and unlatching component.

摘要： A firearm comprises a barrel having a bore and a receiver forming an ignition chamber. A bolt is slidable in the ignition chamber and includes a striker projection for igniting a primer of the projectile. A bolt advancing mechanism comprises an arm having a first end mounted on the bolt such that a second end of the arm is movable laterally relative to the fore-aft axis. A boss is carried at the second end of the arm. An actuator member is movable in the fore-aft direction relative to the bolt and boss, and includes a first cam surface inclined relative to the fore-aft axis for urging the boss forwardly and laterally. The boss is movable laterally along the first cam surface in response to the boss becoming aligned with a lateral groove in the receiver. Such lateral movement of the boss is in a direction tending to displace the bolt forwardly. The actuator member (i) pushes the boss and bolt forwardly to shift the projectile to a firing position, (ii) cams the boss into the groove to further displace the bolt forwardly and ignite the primer, and (iii) blocks movement of the boss from the groove until ignition occurs, whereupon a second cam surface displaces the boss outwardly.
摘要翻译：火器包括具有孔的桶和形成点火室的接收器。螺栓可在点火室中滑动并且包括用于点燃射弹底漆的撞针突起。螺栓前进机构包括臂，其具有安装在螺栓上的第一端，使得臂的第二端相对于前后轴线可横向运动。在手臂的第二端有一个老板。致动器构件可相对于螺栓和凸起在前后方向上移动，并且包括相对于前后轴线倾斜的第一凸轮表面，用于向前和向外推动凸起。响应于凸台与接收器中的横向凹槽对准，凸起沿着第一凸轮表面横向移动。凸台的这种横向运动是倾向于向前移动螺栓的方向。致动器构件（i）向前推动凸起并将其弹弹以将射弹移动到击发位置，（ii）将凸台凸起到凹槽中，以进一步向前移动螺栓并点燃底漆，并且（iii）阻挡凸台的运动从凹槽直到发生点火，于是第二凸轮表面向外移动凸台。

摘要： The actuating part of the breech mechanism comprises at least one longitudinal housing open towards the front and laterally towards the inside and towards the outside of the weapon, in which is mounted on actuating slider free to be displaced towards the front with respect to said actuating part but in rearward abutment by thrust of a rear support surface against the bottom of said housing. The actuating slider comprises, forwardly, a front stop surface projecting forwardly at the periphery of the actuating part and occurring on the withdrawal path of the corresponding movable actuating unit and, at its side oriented towards the inside of the weapon, a protuberance projecting in the direction of the breech block through the inner lateral opening of the housing of the slider concerned. This protuberance comprises a rear engagement notch adapted to come into contact with a rear shoulder fast to the breech block and situated (assuming the slider in the extreme forward position) behind said engagement notch at a distance from the latter at least equal to the withdrawal stroke which the actuating part of the breech mechanism must traverse to free the bolt from the breech block.
