Abstract
Description
La presente invención se refiere a una bocacha apagallamas para arma de fuego, especialmente adecuada para colocación en ametralladora MG (modelos: MG1, MG1A1, MG1A2, MG1A3, MG1A5, MG2, MG3 Y MG3E, KSP 94 y MG7, 62 KK), para munición de 7,62 milímetros. 10 The present invention relates to a firearm flame arrester, especially suitable for placement in MG machine guns (models: MG1, MG1A1, MG1A2, MG1A3, MG1A5, MG2, MG3 AND MG3E, KSP 94 and MG7, 62 KK), for 7.62 mm ammo. 10
Cuando un tirador efectúa un disparo, se produce en la boca del cañón un gran fogonazo que es perceptible por cualquier observador, máxime si el disparo se produce en condiciones de 15 luz escasa (atardecer o en la noche). When a shooter fires a shot, a large flash is produced in the mouth of the cannon that is noticeable by any observer, especially if the shot occurs in conditions of poor light (sunset or night).
Algunas armas de fuego incorporan un apagallamas que intenta en lo posible precisamente sofocar la llama en su seno para que no sea visible. Some firearms incorporate a flame arrester that tries as much as possible to quell the flame in its bosom so that it is not visible.

Concretamente, la ametralladora MG (modelos:MG1, MG1A1, MG1A2, MG1A3, MG1A5, MG2, MG3 Y MG3E, KSP 94 y MG7, 62 KK) incorpora un apagallamas que comprende una cámara o campana interna para que se produzca en la misma el fogonazo, provista de la salida a continuación que consiste en un conducto abocinado en su boca, a modo de trompeta, comprendiendo la cámara unas entradas de aireación en su zona proximal para 25 posibilitar la entrada de aire necesaria para que se produzca la combustión de la llama, que queda cubierta por la campana para intentar ocultarla. Specifically, the MG submachine gun (models: MG1, MG1A1, MG1A2, MG1A3, MG1A5, MG2, MG3 and MG3E, KSP 94 and MG7, 62 KK) incorporates a flame arrester comprising an internal chamber or hood to produce the same flash, provided with the outlet below consisting of a flared duct in its mouth, as a trumpet, the chamber comprising aeration inlets in its proximal area to enable the entry of air necessary for combustion of the flame, which is covered by the bell to try to hide it.
Por otro lado, este apagallamas existente no cumple con los requisitos de apagar el fogonazo con efectividad, y la huella visual es considerable, de tal manera que cuando se utiliza el arma 30 con bajos niveles de luz el operador es detectable a grandes distancias, poniendo en riesgo su integridad y el de la operación. Así, la posición del tirador es detectable fácilmente por cualquier observador que mire en su dirección, y por lo tanto es vulnerable a cualquier reacción, dado que ha delatado su posición. On the other hand, this existing flame arrester does not meet the requirements of effectively extinguishing the flash, and the visual footprint is considerable, so that when the weapon 30 is used with low light levels the operator is detectable over long distances, setting at risk its integrity and that of the operation. Thus, the position of the shooter is easily detectable by any observer who looks in his direction, and therefore is vulnerable to any reaction, since he has betrayed his position.
La bocacha apagallamas para arma de fuego de la invención tiene una configuración esencialmente abierta, que además de producir una efectiva ocultación de la deflagración, 5 afecta mínimamente a la trayectoria y potencia de disparo precisamente por su configuración esencialmente abierta. Además tiene un peso reducido en comparación con otras bocachas. La bocacha de la invención no altera la estructura básica del arma y con una insignificante variación en el peso total, resuelve de forma plenamente satisfactoria la eliminación total de la huella visual tras el disparo. Esto se consigue, además con un reducido costo, con una gran 10 simplicidad de montaje y aumenta las prestaciones del arma básica. The firearm flame arrester of the invention has an essentially open configuration, which in addition to producing an effective concealment of the deflagration, 5 minimally affects the trajectory and firing power precisely because of its essentially open configuration. It also has a reduced weight compared to other bocachas. The bocacha of the invention does not alter the basic structure of the weapon and with an insignificant variation in the total weight, fully resolves the total elimination of the visual footprint after firing. This is achieved, in addition to a reduced cost, with a great simplicity of assembly and increases the performance of the basic weapon.
De acuerdo con la invención, la bocacha comprende: According to the invention, the bocacha comprises:
-un cuerpo tubular del que se encuentran dimanando en sentido distal unos brazos longitudinales perimetrales, 15 -a tubular body from which perimeter longitudinal arms are arising distally, 15
-unas rasgaduras dispuestas entre dichos brazos, y -a tears arranged between said arms, and
-unos medios de fijación del cuerpo tubular a la punta del cañón del arma, que comprenden una prolongación tubular roscada para acoplamiento a la punta de la carcasa del arma y unas hendiduras exteriores radiales perimetrales para la inserción de un retén antigiro. - means for attaching the tubular body to the tip of the barrel of the weapon, which comprise a threaded tubular extension for coupling to the tip of the weapon casing and radial perimetral outer grooves for the insertion of an anti-rotation retainer.

De esta forma los brazos longitudinales perimetrales tienen la longitud suficiente para que se apegue la llama en su seno, y como no tienen configuración cerrada la deflagración tiene espacios por donde salir (las rasgaduras) sin afectar al proyectil, esto es, se redireccionan los gases calientes que se producen tras el disparo, impidiendo el fogonazo, haciendo que este no sea visible a simple vista u ojo desnudo, ni siquiera con medios térmicos de detección. Por 25 su parte, los medios de fijación permiten su fijación roscada a la carcasa del arma correspondiente, y las hendiduras permiten la entrada de un retenedor antigiro provisto en el arma con la finalidad de que los disparos no provoquen el desenroscado de la bocacha. In this way, the perimeter longitudinal arms are long enough for the flame to attach to its bosom, and since they do not have a closed configuration, the deflagration has spaces to exit (the tears) without affecting the projectile, that is, the gases are redirected hot that occur after the shot, preventing the flash, making it not visible to the naked eye or naked eye, even with thermal detection means. On the other hand, the fixing means allow their threaded fixing to the corresponding weapon housing, and the slits allow the entry of an anti-rotation retainer provided in the weapon so that the shots do not cause unscrewing of the mouth.
La figura 1 muestra una vista de una ametralladora que incorpora la bocacha de la invención. Figure 1 shows a view of a machine gun incorporating the mouth of the invention.
La figura 2 muestra un detalle ampliado de la boca de la ametralladora con la bocacha acoplada. Figure 2 shows an enlarged detail of the machine gun's mouth with the mouth attached.
La figura 3 muestra una vista similar a la de la figura 2, con la bocacha desacoplada de la boca del cañón de la ametralladora. 5 Figure 3 shows a view similar to that of Figure 2, with the mouth uncoupled from the mouth of the machine gun barrel. 5
La figura 4 muestra una sección transversal de la bocacha a la altura de los brazos longitudinales. Figure 4 shows a cross section of the mouth at the height of the longitudinal arms.

Igualmente se ha previsto la disposición en dichos brazos (3) de unos canales (6) exteriores de profundidad aproximadamente igual a la mitad del 25 espesor de los brazos (3) para facilitar el roscado. Por su parte, los brazos (3) comprenden una longitud de 155mm y unas disminuciones progresivas de espesor (7), con un espesor en el extremo distal de 8 mm. ya que en estas dimensiones se ha comprobado que se apaga la llama y son contenidas. Specifically, in the preferred embodiment, the mouth (1) comprises three arms (3) of 120 degree angular amplitude, and three tears (4) of 10 mm amplitude, the arms (3) comprising a thickness of 8 millimeters. Likewise, the provision in said arms (3) of external channels (6) of depth approximately equal to half the thickness of the arms (3) is provided to facilitate threading. On the other hand, the arms (3) comprise a length of 155mm and progressive decreases in thickness (7), with a thickness at the distal end of 8mm. since in these dimensions it has been verified that the flame goes out and they are contained.
