The invention relates to a projectile to an animal from a distance to deliver drugs that from a Firearm is fired by means of compressed gas generated when firing, the hollow body through a sliding separating piston divided into a pressure chamber and a space for receiving the drug is and whose front end carries a double-pointed hollow needle, which with its rear Tip enters the space containing the drug when the front tip hits the carcass.

Such projectiles are known.
All of these bullets described have the serious disadvantage that the gas which is used to propel the liquid drug into the body of the animal must be produced within the bullet by gas generating means.

Since the projectiles are usually stored for a long time until they are used, it can happen that the means for Generating the gas will deteriorate or the device will fail because of the surrounding mist discharges or discharges too early as a result of incorrect handling.

A projectile is also known in which a needle is inserted when it strikes the animal's body Water tank bumps. The released water reacts with chemicals in such a way that inside the A compressed gas is produced by the bullet, which takes the drug through a hollow needle via a piston and into the animal's body drives. Finally, a bullet is known which has a double-sided pointed end at the front end Has a hollow needle. When the bullet hits the carcass, the rear tip of the Hollow needle into a compressed gas capsule contained in the projectile, and the compressed gas emerging from the capsule drives the drug into the animal's body via the front hollow needle.

Also for these two well-known types of bullets

The above statements about the state of the art essentially apply. That for driving the liquid drug in the animal's body is used either after hitting the gas Animal carcasses generated in the projectile, or it is already contained in the projectile before the launch. In the former

These disadvantages of the known projectiles are avoided according to the invention in that the back the pressure chamber has a valve device, which is a part of the generated when firing Pressurized gas can enter the pressure chamber and then this chamber closes after the launch, so that the gas pushes the piston against the drug.

According to the invention, a part of the launch gases is stored in the projectile until the projectile hits the Carcass hits. Then the rear tip of the hollow needle pierces a wall so that the liquid drug under the pressure of the stored launch gas, which is due to the escape the liquid drug can expand through the needle penetrates the animal's body.

The required gas pressure is generated either immediately before the projectile is fired or at the same time as it is fired. When the bullet is stored, there is no pressurized gas in it, and none can form either. By using part of the launch gases to drive in the drug, there is a guarantee that the projectile will work properly at all times. This gas is not susceptible to aging or decomposition from prolonged storage. There can also be no self-discharge of stored projectiles.
In an advantageous embodiment of the invention, the projectile is made of plastic, and a partition made of plastic is provided between the rear tip of the needle and the drug.

Claims (1)

3 4 This partition can be easily rotated from the top to the front part of the will come across. Body 12 screwed in and from this again The following are the main features to be resolved. of the subject matter of the invention and its advantages takes place under The operation of the subject matter of the invention Set out with reference to the drawing example. 5 as follows: F i g. 1 is a side view of a bullet after the bullet is used the invention; Plug 18 removed so that the space between F i g. Figure 2 is an enlarged perspective view of the propulsion link 15 and the front end of the body position one embodiment of the valve mechanism, pers 12 is open. In this space there is a liquid which is used to fill the gas pressure in the drug 17 and the plug 18 by means of it let the shot enter; Projections 42 moved back into its closed position F i g. 3 shows an enlarged perspective screwed on. At this point the parts take the position of an embodiment of the valve opening in FIG. 4 position shown. attached mechanism to control the feed The bullet is then inserted into a firearm rens and the retention of the gas pressure in the 15 out. The gun is aimed at an animal and Bullet; shot down. At this point in time, which is shown in FIG F i g. Fig. 4 shows, on an enlarged scale, a longitudinal part of the gas 45 exerted for cutting of the in FIG. 1 floor shown. In this shoot out the projectile 11 from the barrel Figure are the parts of the projectile used in their weapon 46, putting a pressure on the body normal position before firing; ao 34 off. This is pushed forward because the pin 35 FIG. 5 is a partial longitudinal section of the elastic material shown in FIG. 4. Through this showed bullet, after this in the shot, an opening is created through which part 47 of the weapon is introduced, at the time of firing pressurized gas 45 in the pressure chamber 48 behind the and shows the means for letting the gas enter the propulsion member 15. But this compressed gas can Bullet; 25 do not drive the propulsion member 15 forward because the F i g. Figure 6 is a similar representation to Figure 7K, wall 21 preventing drug 17 from escaping, but shows the parts of the projectile in position and because normally a liquid cannot be squeezed immediately after striking the animal. Capture the projectile 11, let the firearm 46, the needle 27 hit the The projectile 11 has a body 12 and an animal 48 and penetrates its body. the Pair of wings or the like 13 and 14, which at the end of the penetrating tip 29 is through the collar 49 zuGeschosses are attached and retained from this. The plate 26 that is too wide to protrude. A propulsion member 15, which can penetrate a variety of into the body of the animal, is of the Has grooves 16, is slidably stopped in the outer skin, and the inertia of the body Body 12. 35 12 causes the needle carrier to move forward A liquid drug 17 is introduced into the body 12 in front of and through the tip 30 of the needle 27 the wall 21 the propulsion member 15 is filled. The space 48 α in pierces. As a result, the liquid 17 the body 12 behind the propulsion member 15 is considered to emerge through the opening 28 of the needle 27. That Called pressure chamber. A plug 18 with a release of the pressure in the liquid causes Collar 41 has a thread 19 for screwing 40 that the gas 47 pushes the propulsion member 15 and in the thread 20 in the front end of the body, the liquid drug is pressed into the body of the animal 12. The plug 18 has a wall 21. see that is usually not pierced. The body 12 can expediently be made of deformable plastic, such as polypropylene, which extends from the front surface 23 of the 45 len, polyethylene or other thermoplastic plug 18 to near the wall 21 in the plug 18.
