摘要： PROBLEM TO BE SOLVED: To obtain a machine gun in which even a large caliber bullet can be fed by locating a duct in front of a battery bearing part in order to reduce overall size and providing the duct with a bullet feeding bearing part thereby making the duct of a hard material. SOLUTION: A machine gun and the bullet feeder thereof are reduced in size by providing a duct 6 forward from the battery bearing part 3 and the duct 6 is provided with a bullet feeding bearing part 8. Since the duct 6 is made of a hard material so that it is interlocked with inclination/declination of the machine gun 1, even a large caliber bullet 35 can be fed.

摘要： PURPOSE:To shorten the length of powder cases so as to reduce the difference in length between a shell and the powder cases by a method wherein a powder case and shell are assembled in one piece by connecting the powder case to the bottom of the shell to form an ammunition, the remaining powder cases are formed separately from the shell. CONSTITUTION:A main body 7, made of a burning-out material, or a first powder case 6 is firmly connected to the bottom of a shell 3 by a fixing protrusion 8. In the main body 7, a portion of powder 10 required for firing the shell and a fuse column 11 are housed. When the ammunition is loaded into a barrel, the first powder case 6 of a shell section 2 and a second powder case 13 of a powder case section 12 are connected in one piece by protruding and recessed parts 9 and 19 for fitting.

摘要： PURPOSE:To realize an equipment-cooling device whose structure is simple and whose efficiency is high by a method wherein a thermoelectric cooling element is used so as to absorb the heat from the air circulating between the heat-absorbing surface and a part to be cooled through the heat-absorbing surface while the heat is dissipated to the outside through the heat-radiating surface. CONSTITUTION:When the inside of boxes 3-6 as objects to be cooled is to be cooled, an electric current is made to flow through a thermoelectric cooling element 15. Then, a heat-radiating surface 15a of the thermoelectric cooling element 15 radiates the heat due to the Peltier effect, and a heat-absorbing surface 15b is cooled. When blowers 10, 11 start operating, the outside air is introduced into a heat-dissipating path 7 through an opening on one side; the air is blown to a heat-dissipating plate 12 and heat-dissipating fins 13, 14; the heated air is discharged to the outside through an opening on the other side of the heat-dissipating path 7. In addition, when blowers 22-25 start operating, the high-temperature air inside the boxes 3-6 is introduced into heat-absorbing paths 18-21 through the opening on one side; the high-temperature air is blown forcedly to a heat-absorbing plate 16 and a heat-absorbing fin 17 and is cooled.

摘要： PURPOSE:To miniaturize an ammunition supply device by providing a bullet feeder around an angle of depression or elevation of a gun, and delivering an ammunition from the feeder to a charger irrespective of turning of a gun. CONSTITUTION:After an arbitrary ammunition 90 in an inner drum unit provided in an external drum unit 20 of bullet feeders 18, 19 is so aligned as to be opposed to a bullet feeder 18a of the unit 20, it is rotated synchronously with depression or elevation of a gun. Thus, even when the gun is depressing or elevating, a selected ammunition 90 is maintained in a state opposed to the bullet feeder 18a. The ammunition 90 is fed from the feeder 18a to bullet conveyors 70, 71 in this state. The conveyors 70, 71 convey the ammunition 90 to a specific position, and delivers it to a charger of a gun side. Thus, delivery of the ammunition 90 from the feeders 18, 19 to the charger is conducted irrespective of a turning of the gun, and a device can be miniaturized.

摘要： PURPOSE:To enable shock occurred when stopping of shooting to be eliminated by a method wherein a bullet feeding passage ranging from each of bullet feeding machines to a bullet feeding wheel in a machine cannon having a pair of bullet feeding machines is provided with a stopper member. CONSTITUTION:A machine cannon is provided with a bullet feeding wheel 25 between a breechblock movebly arranged at a main body of a machine cannon in such a way that operations of advancing, stopping, retracting and stopping in a central axial direction of a barrel under an operation of a driving mechanism are carried out in sequence and the barrel. To the bullet feeding wheel 25 is intermittently supplied a bullet chemical 9 from bullet feeding machines 2a, 2b storing a plurality of bullet chemicals 9 (9R, 9L) through bullet feeding passages C, D. In this case, there are provided stopper members 35a, 35b which can be changed over between a releasing position allowing a passing of the bullet chemical 9 and an engaging position prohibiting its passing. The stopper members 35a and 35b are selectively set at the releasing position/engaging position to enable either starting or stopping of shooting to be controlled without having any relation with the operation of the bullet feeding wheel 25.

摘要： PURPOSE:To provide a low entire height of a gun and to enable the gun to be transported on the land by a method wherein a bullet box is fixed and disposed at a position different from a turning shaft of a main body of the gun and a bullet supplying slip ring is arranged at an intermediate between the main body of the gun and the bullet box. CONSTITUTION:A bullet supplying slip ring 6 is arranged coaxially with a turning shaft of a main body 1 of a gun below a gun frame 2. A bullet box 17 fixed to a bullet box fixing table 18 arranged on a base block 4 of a tracting trailer is disposed at a position different from the turning shaft of the main body 1 of the gun. Accordingly, even if the bullet box 17 is made large through a large diameter setting of the main body 1 of the gun, it does not accept any influence from the bullet box 17, an entire height of a machine gun can be reduced low and the gun can be made into a retracting type trailer machine gun which does not provide any trouble in a land transportation. A tire 25 of the retracting trailer can be lifted up and openable or closable supporting legs 27 and 28 are disposed, so that a center of gravity of the machine gun can be set low when a machine gun firing occurs and then a stable shooting can be carried out.
