    Weapons with delay function, which weapon is magazine-equipped with its principle of operation, self-loading with gas piston function. The delay function prevents the self-loading weapon from sliding and locking during firing and keeps them closed. The design of the delay function stores the energy of the powder gas for later use, either mechanically or pneumatically, for the firing or closing mechanism of the firearm. The weapon with delay function has a delay function mechanism consisting of a body (E) and in this placed guide (C) with holes (D), through which holes (D) gunpowder gas with high pressure can come via the weapon's barrel (A) to the gas piston (F ), which moves with a rod (H) as a bushing, rod (H) attached to the bottom piece (I). In connection with the rod (H) there may be a spring (G), which spring (G) or alternatively the gas piston (F) of the air compresses the pressure of the gunpowder gas against the bottom piece (I). The stopper (K) stops the gas piston (F) in its rear position and leaves the spring (G) or air under compression. When the shooter or possible separate automatic function uses a release (L), the bottom piece (I) can rush backwards with force from the compressed spring (G) or the air. The base (I) is in firm contact with the weapon slide (O), which uses the weapon's loading and closing mechanism to perform sleeve removal and loading functions.

    DELAYED GUN
    FIELD OF THE INVENTION The invention relates to weapons technology. The invention relates to a loading mechanism for a self-loading gas-piston firearm, i.e. the removal of the cartridge from the cartridge case after a shot has been fired and the feeding of a new cartridge into the cartridge case, focusing on the temporal control of this event.
    BACKGROUND OF THE INVENTS This € very hot and high-pressure gas is partly directed from an opening in the barrel of the gun to a gas piston placed inside the cylinder. The force from this gunpowder gas pushes the gas piston backwards. This force is passed on to the slide and lock, which, when retracted, open, allowing the shotgun stuck to the lock of the gun to be removed from the cartridge case. At the same time, however, hot, scorching gunpowder is released inside the gun through the opening slides and lock. By the force of the return spring, the lock and slide return to the forward position, taking a new cartridge from the magazine or magazine to the cartridge housing, allowing a new shot. This chain of events occurs in a fraction of a second without the shooter being able to influence it after the cartridge is fired. S
    OBJECT OF THE INVENTION
    N z In a delayed-action self-loading gas-pistol firearm c 25 - After firing a shot, the gun slide and lock remain in place. They are allowed = to plunge backwards only when the shooter so decides or automatically delayed O, however, so that the bullet fired has left the barrel of the gun and the pressure of the gunpowder has completely disappeared from the barrel. - This has the advantage over traditional self-loading firearms that the moving parts of the firearm do not swing the weapon when moving, colliding, pushing forward or colliding in the forward position, thus improving the accuracy of the firearm. The delay function calms the shooting moment that requires accuracy, making it similar to a one-time operation, i.e. the so-called the moment when the bolt-locked weapon 35 is fired. The advantage over a single-action firearm is that the firing position does not need to be unloaded to reload the gun manually and a new shot can be fired faster. In addition, the mechanism of a delayed firearm stays cleaner and cooler than a 40 - traditional self-loading firearm, because a permanent lock and slider that remain in place during firing do not allow hot, scorching gunpowder to enter the gun mechanism, unlike traditional self-loading firearms. This feature is further enhanced by the use of a muffler in the gun, with gunpowder gases emptied backward toward the gun machinery. 45 The delay-action firearm gives the fired bullet a higher launch speed due to the fact that the power of the gunpowder is not allowed to dissipate in undesired directions as is the case with traditional self-loading firearms. This improves the accuracy of the weapon and the power of the bullet. 50 The safety of a delayed firearm is better compared to a traditional self-loading firearm with a cartridge when using the reload time decided by the shooter. This is because the empty cartridge fired in the delayed firearm N remains in the cartridge case, preventing damage shots if the firearm is left unattended after 55 shots. o - In order to achieve these objects, the invention is characterized by what is stated in the characterizing part of appended claim 1. R
    S S 60 — DESCRIPTION OF THE INVENTION The gunpowder of a cartridge fired in a delayed firearm is directed through a gas port machined into the barrel of the weapon into a cylindrical tube containing a spring-loaded gas piston. A rod passes through the gas piston, and at the end of the gases coming from the barrel there is a guide through which openings have been machined through which the pressure of the 65 - gunpowder gases can reach the gas piston itself. At the opposite end of the rod is a base piece to which the rod is attached and the spring of the gas piston rests. This base piece is connected to the slide of the gun. In addition, there is a spring-loaded retainer and release.
    The gunpowder pressure comes from the barrel of the gun through the gas gate into a cylindrical tube, passes through holes machined in the 70 guide to the gas piston, which moves backwards from the gunpowder pressure and at the same time presses the spring against the base. As the gas piston moves backwards, it locks in the rear position as the retaining claw of the detent engages the front edge of the gas piston.
    75 - The release holder holds the base in place on its retaining claws. When the shooter releases the release lever attached to the body release or the possible automatic delay function uses that release, the body can be pushed back by the force of the compressed spring, causing the weapon slider and lock to move backward as in traditional self-loading firearms. In this case, the fired sleeve 80 - can be removed from the cartridge case and the weapon and the weapon retuned. The release lever can also be attached to the trigger of a weapon, for example. The delay function can be used on both long and short shotguns.
    An air duct can also be machined into the structure, which leads to the space between the gas piston and the base 85. This solution reduces the pressure differences in the space between the gas piston and the base compared to the ambient air pressure. These N pressure differences arise from the relative movements of the gas piston and the base body. This air duct facilitates the operation of the spring if the dimensions of the parts require it.
    o - 90 - The return spring of the weapon returns the moving parts of the weapon to its front, i.e. starting position i, while taking a new cartridge from the magazine or magazine to the cartridge housing and the weapon is ready = for a new shot. At the same time, the return spring of the weapon also returns the parts of the S delay function mechanism to its forward or starting position. Bevel machined the surfaces cause the retainer claws of the retainer and release to deflect when returning to the home position 95.
    By keeping the release open during firing, the delayed weapon works without delay, like a traditional self-loading weapon. On the other hand, the structure can be constructed in such a way that the delayed weapon acts like a traditional self - loading weapon without the 100 - delay function, and only by separately activating the release does the weapon become delayed. The design also allows a separate selector to select which of the operating principles is in use. The mechanical spring can also be replaced by a pneumatic system in which air is compressed instead of the spring to store energy. The invention is characterized in that the force of the gunpowder pressure is stored and that force is available later to operate the gun loading and closing mechanism either at a time selected by the shooter or at a time 110 determined by the automatic delay function. In addition, the invention is characterized by what is set forth in the characterizing part of the appended claim 1. 115 —LIST OF FIGURES The invention will now be described in detail with reference to the accompanying drawings, in which Fig. 1 shows a delay function in its initial position before firing a shot, S Fig. by force of. E The figures are drawn from the side in cross-sectional views.
    R S. N 125 — DETAILED DESCRIPTION OF THE INVENTION
    N The following is one possible implementation for the delay mechanism of a delayed firearm.
    FIGURE 1 130 - After firing a weapon, a bullet passes the opening of the gas gate (B) in the barrel (A) of the weapon, from which very hot and high pressure gas can escape through the gas openings (D) machined through the guide (C) to the gas piston (F) inside the body (E). . FIGURE 2 135 —The gas piston (F) plunges backwards under the action of the pressure through the rod (H), pressing the spring (G) against the base piece (I). The throttle piston (F) locks in its rear position when retained by the retainer (K). The retainer (K) is operated by a spring (J). FIGURE 3 140 - The shooter uses a release lever (L) that moves the release (M), which is loaded by a spring (N). The retaining claw of the release (M) releases the base piece (D) in rigid contact with the gun slide (O). The force of the compressed spring (G) causes the base (I), the rod (H) and the guide (C) rigidly connected to it, and the gun slider (O) to plunge backwards, allowing the fired cartridge to be removed from the cartridge case and gun and the 145 new cartridge to be loaded from the magazine or magazine. The controller (€) also takes the gas piston (F) with it when pushing backwards. The return spring of the weapon pushes the moving parts of the weapon back forward and the delay mechanism returns to the state shown in Figure 1 to wait for the next shot by the same return spring. The sloping cutting surfaces (P, O, R, S) of the delay mechanism cause the retainer (K) and the 150 - release (L) to recede away from the front of the guide (C), the gas piston (F) and the base (I), after which the retainer (K) and the release (L) return to the state Q according to Figure 1 by the force of the springs (J, N). The implementation can be implemented advantageously also without separate ones
    O N springs (J, N) with the retainer (K) and release (L) body acting as a spring-like elastic
