ることができる。 To further explain the operation of the present invention, the relationship between the automatic ejection shell 1 and the firing pin 8 is such that, before firing, as shown in FIG. A gap is provided between the fitting portion 10 of the firing pin 8 and the fitting portion 10 of the firing pin 8, respectively. The built-in piston 11 is fitted tightly into the inner surfaces of the recess 4 and the hollow part 7, and since the piston 11 is made of high-density polyethylene resin, it has elasticity and Unlike metals, it has a low coefficient of friction, so dimensional accuracy is not required compared to conventional products. From the above state before firing, the third
When firing is performed as shown in the figure, the piston 11 is compressed and deformed by the pressure of the gunpowder gas generated, and the gap formed between the inside of the cartridge and the outside diameter of the piston 11 is instantly sealed. , converts the generated gunpowder gas into retreat energy without wasting it. This is published in Utility Model Application No. 57-13999 and Utility Model Application No. 57-14000.
This is different from the one in the publication. At the same time, the piston 11 and the firing pin 8 separate, and the sealed gunpowder gas is discharged all at once, making it possible to generate an extremely loud noise and a large amount of smoke compared to conventional systems.

いる。(1) The present invention is as described above, and the built-in piston is made of high-density polyethylene resin with a square cross-section to have appropriate elasticity and reduce the coefficient of friction. Unlike the metal pistons disclosed in Japanese Patent Publications No. 57-13999 and No. 57-14000, there is no requirement for dimensional accuracy in the gap between the built-in cartridge and the outside of the piston compared to conventional pistons. Natsutato and
Furthermore, the dimensional accuracy of the gap between the fitting portion of the firing pin and the fitting hole of the piston has the advantage that, as described above, dimensional accuracy is not required compared to the conventional one.

点を有している。(2) Furthermore, since the piston of the present invention has elasticity, it is compressively deformed by the pressure of the gunpowder gas generated during firing, instantly sealing the gap between the inside of the cartridge and the gas generated. It has the advantage of generating louder noise and a larger amount of smoke than conventional systems because it immediately converts it into retreat energy without wasting it and exhausts the sealed gas all at once.

できる等多数の優れた利点を有している。(3) In addition, the piston of the present invention has a low coefficient of friction, so the number of cleaning steps is significantly reduced compared to conventional pistons, and the piston can be mass-produced by injection molding at low cost. Compared to ejected shells, it has a simpler structure and has many advantages, including the ability to significantly reduce manufacturing costs.
