摘要： PURPOSE:To restrict an explosion sound at the time of occurrence of phenomenon of back-fire and to enable a safety in operation to be attained. CONSTITUTION:A plurality of pressure releasing holes 11 are concentrically arranged at a piston head 8a of an injection piston 8. A valves seat 12 having a recessed section is arranged in an annular form in such a manner that openings of each of pressure releasing holes 11 at a side of a combustion chamber 6 are connected to each other, and a safety valve 13 is arranged to close the pressure releasing holes 11. The safety valve 13 is arranged such that a valve main body 13a composed of cylinder is axially guided and supported by a valve guide 13b and resiliently biased rearwardly by a compression spring 13c. A resilient force of the compression spring 13c is set such that the main body 13a of the valve is closely contacted to and engaged with the valve seat 12 until a fuel chamber 7 shows a predetermined pressure and the pressure releasing holes 11 are kept at their closed states. At the time when the fuel chamber 7 shows the predetermined pressure due to a phenomenon of back-fire, the valve main body 13a moves forwardly and is moved away from the valve seat 12 so as to release the closed state of the pressure releasing holes 11. With such an arrangement as above, the fuel chamber 7, combustion chamber 6 and fuel chamber 7 communicate with each other and the pressure in the fuel chamber 7 is released.

摘要：本实用新型涉及的枪炮速射气压复进装置，它包括枪管、枪机、导气孔、回气管、排气孔、回气管活塞、复进簧，所述回气管活塞后部套装有复进簧，其尾部与枪机相连，它还包括有废气导管、废气储气室，进气单向阀、排气复进单向阀、气缸筒和气压顶杆；通过本技术方案，它不但可以有效的提高射速，还可以通过气流的双向工作减小射击时的后坐撞击力，在恶劣环境下，泥沙和尘土或树枝等异物经常从抛壳窗进入机匣并沉积在自动机导轨上，给枪机的复进带来巨大的阻力，本装置则大大提高了枪机向前运动的作用力，不但能够有效的克服这些阻力，而且可以减少或杜绝由此而造成的枪机运动不畅和甚至发生的卡弹、滞弹现象。

摘要： A receiver assembly for a rifle includes a receiver with a feed assembly configured for open-bolt operation. A feed cover is hingedly mounted to the receiver and includes one or more components of the feed assembly, where the feed cover is movable between a closed position and an open position by pivoting about a hinge pin oriented along a longitudinal axis of the receiver. For example, the feed cover can pivot to one side of the receiver when in the open position. A rifle incorporating the receiver assembly is also disclosed.

摘要： Vorgeschlagen wird Waffensystem mit einem Verschluss, der zumindest von einem Verschlussträger (5) und einem Verschlusskopf (3) gebildet wird, wobei der Verschlussträger (5) so ausgebildet ist, den Verschlusskopf (3) zu tragen. Um zu erreichen, dass die beim Entriegeln des Verschlusses und des Ausziehen einer Patronenhülse auf den Verschlussantrieb einwirkenden Kräfte minimiert bis hin beseitig werden, ist der Verschlusskopf (4) gegenüber dem Verschlussträger (3) frei beweglich. Zur Trennung des Verschlusses mit einem Verschlussantrieb des Waffensystems beim Rücklauf der rücklaufenden Massen des Waffensystems, ist eine Vorrichtung (20) derart ausgebildet, dass eine mechanische Trennung zwischen dem Verschluss und dem Verschlussantrieb beim Rücklauf der rücklaufenden Massen des Waffensystems erfolgt. Beim Vorlauf der rücklaufenden Massen wird über die Vorrichtung (20) die mechanische Verbindung zwischen dem Verschlussantrieb und dem Verschluss wieder hergestellt. Für das T rennen oder Verbinden des Verschlusses von einem Verschlussschieber (6), der mit dem Verschlussträger (5) funktional zusammenwirkt, weist die Vorrichtung (20) zumindest eine Verbindungsstange (23) auf. Die Verbindungsstange (23) ist mit einem, in Schussrichtung gesehen, hinteren Ende fest am Verschlussschieber (6) angebracht. Das vordere Ende kann mit dem Verschlussträger (5) verbunden und von diesem getrennt werden.

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 weapons system for single-barrel automatic cannons uses PRUNIT rounds consisting of a projectile and a casingless solid body of propellant affixed to the projectile. A respective arming set is provided for at least some of said weapons to form central units therewith. Each arming set comprises means defining first and second energy-flow paths with respective shafts adapted to transmit torque from input ends to output ends of the path. Both of the shafts are connected to a wedge-type breech block for shifting same between open and closed positions. One of the shafts is connected to a loader and the other to a belt feeder for the PRUNITs.
