摘要： In order to ensure that forces acting on a breech drive when unlocking the breech and pulling out a cartridge case are reduced or even eliminated, a breech of a weapon system is proposed which is formed at least by one breech carrier and one breech head and the breech carrier supports the breech head. The breech carrier and the breech head can be mechanically separated from one another. This separability is achieved in that a control case which has at least one control cam is inserted in the breech carrier. In addition, the breech head has a control bolt which engages in the control cam of the control case and can be guided in it. This measure ensures that the forces acting upon the recoil of the weapon cannot act on the breech drive.

摘要： A compact 50 caliber machine gun system which utilizes an original Browning rear-stripping ammunition link design. The chain-driven machine gun system features a delinker assembly configured to receive a belt of linked cartridges, separate each of the cartridge from the belt rearwardly, and feed each of the cartridges for firing. The delinking function is separated from the motion of the bolt assembly so as to reduce the overall length of the gun system. The receiver has a receiver mounting length RML from the rear base of each incoming cartridge in a belt of connected links to the rear end of the receiver that is less than 15 inches. A shuttle feed system is incorporated into the basic chain gun style mechanism which had been limited to a sprocket feed on all previous designs. An electronic anti-hangfire system uses a single proximity switch and the already existing parts and motions of the gun.

摘要： An emergency stop device for a weapon with a drive for transporting a breech block of the weapon. At least one guide, at least one connecting rod guided in the guide, and at least one lever are provided. When a shot is not being fired, the kinematic system is deactivated. When a shot is being fired, the at least one guide is moved rearwards, and the at least one connecting rod is guided upwards along the guide such that the lever exerts a lever movement, by means of which the transport of the breech block is made possible. The weapon drive has a complete control slide for transporting the breech block of the weapon. A bolt is laterally embedded in the transverse slide, said bolt being integrated below the complete control slide of the drive in a movable manner in the slide.

摘要： A transmission assembly for transmitting power between a fixed part and a moving part of a weapon, the moving part being disposed to move in response to recoil of the weapon, includes a drive motor, a mechanism, and a transmission device. The drive motor is attached to the fixed part. The mechanism is attached to the moving part. The transmission device is coupled to the drive motor and to the mechanism. The transmission device transmits power from the drive motor to drive the mechanism and includes a telescopic universal joint assembly. As a result, the transmission assembly permits power to be reliably supplied from the drive motor to the mechanism.

摘要： For a space saving and shock free breech block for an externally driven automatic weapon, a control roller 10 includes two camming discs which offset by 180.degree. with respect to one another in a symmetrical manner and arranged one behind the other, so as to continuously rotate in the same direction as the control roller. For the displacement of two locking bars disposed on opposite sides of the breech block 9 in a direction transverse to the direction of movement of the breech block, respective slide members are arranged between the breech block guide path axis and the control roller 10. Each slide member grips around one of the camming discs by meane of a U-shaped pocket and transfers the transverse movement of the associated camming disc to an associated one of the locking bars for locking and unlocking breech block 9 in a form locking manner.

摘要： This invention relates to an arrangement for rapidly stopping an automatic weapon having an external drive where the breech block is driven by parallel shafts. This arrangement provides for the rapid stopping of the shafts and thus the weapon by providing the shafts with coaxially mounted pockets at their ends in which a pair of claws may be engaged to stop the rotation of the shafts.

摘要： A gun of the kind in which liquid propellant is burned in the firing chamber to fire a projectile from the gun is constructed so that a number of gun modules can be combined in a modular gun. Each gun module is cam controlled, and a common cam is used to control each gun module in the modular gun. The cam can be a flexible cam having a belt configuration to permit the gun modules to be arranged in both circular groupings and in non-circular groupings, such as side by side. The modular gun includes fixed, non-rotating gun modules to eliminate the need for tangential velocity correction factors in the fire control and the need to accelerate the mass of the barrel assembly to operational speed. The individual gun module includes propellant injection mechanism for injecting propellant at high pressure when a non-hypergolic bi-propellant is used as the propellant. One or more hydraulic actuators are used to develop the high injection pressures and to operate other components of the gun, such as the bolt. The hydraulic actuators are also engaged with the cam to interlock the actuators and the controls for the actuators through the cam. A source of pressurized hydraulic fluid independent of the gun is used to power the actuators so that the weight and profile of the gun are kept to a minimum. The hydraulic system includes a compound spool control valve which operates in a dual mode to permit normal cyclic operation of the gun during firing and to maintain the gun in an open bolt condition during armed but non-firing operations. The hydraulic system includes a misfire detection mechanism and module shutdown valve which locks a misfired gun module in the closed bolt condition without the need to depressurize the hydraulic circuits of the other gun modules and without the need to include additional bypass circuits. The injection mechanism for injecting the bi-propellant includes two pistons which are yoked together and operated by a single actuator to inject the propellant into the firing chamber both in metered amounts and in a constant mix ratio. The pistons for injecting the bi-propellant include valves in the pistons, and the pistons are drawn through the fuel on retraction strokes of the pistons. The injection mechanism is retracted away from the firing chamber after the firing of a burst to isolate the propellant in the injection mechanism from the heat of the firing chamber. A rotary lock is mounted closely adjacent the bolt mechanism and engages a relieved area of the bolt in the locked position of the lock so that a quite small force on the lock will hold the bolt mechanism locked against high combustion chamber pressures tending to open the bolt.
