| A drive device for the breech mechanism of a gun comprises driving and driven members connected to first and second elements, respectively wherein one of the elements is movable with respect to the other. The driven and driving members are separable as the elements move apart and re-engage as the elements come together. The connections between the members and elements permit the driving and driven members to execute a rotary motion about a common axis when the members are engaged together whereby energy is transferred from the driving member to the driven member. | ||||||

| A drive device comprises driving and driven members, and first and second elements, one of the elements being movable with respect to the other. Energy derived from the coming together of the elements is stored, preferably hydraulically, and transferred to the driving member. Advantageously, the drive device is applied to a gun whereby the device may be used to drive the breech opening and closing mechanism and/or the loading tray. The first and second elements include the beating plate and a part of the breech structure. Energy to be stored and transferred is obtained from the recuperation of the gun after firing. | ||||||

| A device used especially in a large caliber weapon for controlling the train of motion of an ammunition unit during the ramming thereof in the weapon, and of the case of the ammunition unit on firing of the gun includes an impact arrangement which upon ramming of the ammunition unit enter into interaction with and retard the ammunition unit. An energy storing device is chargeable through the impact with kinetic energy existing in the retarding ammunition unit. In response to energy transmitted from the energy storing device the closing of the breech block is activated. The breech block in the closed position retains the case of the ammunition unit during the firing and during a predetermined portion of the rearwardly directed movement in the gun effected on firing. The impact arrangement includes an impact member interactable with a flange on the case and displaceable in the longitudinal direction of the gun, and an impact spring means interactable with the impact member and with an impact piston. | ||||||

| PURPOSE: To block release of a breech block under firing by operating the breech block mechanically to a closing position with the energy stored in an accumulator upon action of an impact ring of a gun through a predetermined longitudinal displacement of an ammunition unit. CONSTITUTION: When a cartridge 2 is pushed into a chamber 1 in arrow direction P, a flange 3 touches an impact ring 4 movable in the axial direction and pushes an impact piston 6 while resisting against a spring 5. An accumulator piston 7 also moves to store energy at the parts 15a, 15b of a cavity 15. When the front part 8a of a breech block 8 arrives at a closing position on the outer circumference 4a of the impact ring 4 while being accelerated, a clamp/unclamp means 10 clamps the breech block 8 at the closing position in a spring 11. Barrel and breech block are retracted and decelerated upon firing and a capturing boss 14 having a piston 14a is operated with pressure in the barrel to compress the spring 11 thus shifting the breech block 8 to a release position. Releasing of the breech block 8 is thereby blocked under firing and safety can be ensured. COPYRIGHT: (C)1991,JPO | ||||||

A drive device comprises driving and driven members (20),(19), and first and second elements (10), (7), one of the elements being movable with respect to the other. Energy derived from the coming together of the elements is stored (31), preferably hydraulically, and transferred to the driving member (20). Advantageously, the drive device is applied to a gun whereby the device may be used to drive the breech opening and closing mechanism (18) and/or the loading tray (73). The first and second elements include the beating plate (10) and a part of the breech structure (7). Energy to be stored and transferred is obtained from the recuperation of the gun after firing. |

| A reciprocating barrel is provided with a breech ring supporting a breech block for vertical and rotatable movement between open and closed positions of the firing chamber. The breech block is mounted on a pin having semi-circular end portions which are positioned within slots in the breech ring which control the vertical and rotational movement of the breech pin carrying the breech block. An actuator operated by explosion gases opens and closes the breech block. Breech latches hold the breech block in its open position, and ejector slides operated by the breech block serve to lock the latches so as to hold the breech block in the open position. The ejector slides are engaged by an incoming round of ammunition to release the latches and the breech block to allow the actuator to close the breech block for the next firing cycle.

A gun is provided with an automatic device intended partly for retardation of a cartridge during the latter portion of its ramming cycle into the chamber, partly for blocking/locking of the cartridge in the chamber, partly for exposure of the spent cartridge case after firing and partly for ejection of the spent case after firing. The device includes impact means (4, 5, 6) which, on ramming of the ammunition unit, enter into interaction with and retard the ammunition unit. Also included is a pressure accumulator (15) which is chargeable via the impact means with existing kinetic energy in the ammunition unit. The breech (8) is closed by means of energy stored in the pressure accumulator. During its activation with the aid of the stored energy the breech enters into interaction with the case and retains this during firing and during a predetermined portion of the rearward-directed motion in the gun occurring on account of firing. |

| 12 | SOFT RECOIL SYSTEM | PCT/US2012034562 | 2012-04-20 | WO2012145705A3 | 2013-02-28 | |
| One embodiment of a gun configured with the soft recoil system comprises a plurality of recoiling parts that initially moves in the direction of the projectile being fired before moving in a direction opposite to that of a projectile during the firing of the round. The soft recoil system throttles the movement of the recoiling parts such that the energy expended during the firing of the round is spread over a longer time period and a longer distance than would normally occur. The soft recoil system stores at least a portion of the energy transferred to the recoiling parts and the user may selectively release at least a part of that portion of energy to offset the energy imparted to the gun during the firing of the next round. | ||||||
