Description

[Detailed description of the invention] Air damping type two element w Purpose of invention The purpose of this invention is to address the current wattage used in the cartridge sector. to provide an air damped two-element watt with many advantages and novelties compared to Background of the invention Current technology prevents the barrel from becoming complexed or copperized by repeated firing. The reinforced pattern also completely seals out the gases generated during powder combustion. In order to made of pieces.

However, the current wattage has many inconveniences as follows; - Perform different firings performed using the same cartridge, wattage and the same rifle. The pattern lacks uniformity when printing.

・Damping is achieved by bending or deforming the constituent materials. As a result, irreversible energy is generated.

・When the gun is throttled, it deforms rapidly.

The pellet is embedded within the material.

-The amount of energy expended during these deformations is high along with the friction against the gun barrel.

-Each charge requires a special dimension of watts, i.e. similar charges Even if the pellet amount is different, such as when the length of the cartridge case is different, It is necessary to change the size of watts each time.

・Watts may fire excessively, causing danger to the shooter and third parties. .

Detailed description of the invention The air damping type two-element watt which is the object of the present invention consists of two elements connected to each other. It consists of a replaceable element, a case, and a damper shutter.

The case has many bendable flaps and damping adjustment and gas injection bars. Works with Rube. Both the case and the damper have uneven cross-sectional walls, and a pair of wood It is possible to absorb radial deformations about the nominal axis.

The damper has four functions: bending and deforming the material, friction against the barrel, and packing. It is effective for compressing air.

The above cartridge wood has the following characteristics compared to regular wood. Ru.

・Strengthening patterns - Minimum energy required to drive the charge.

- The same wood fits different cartridge case lengths and can be used within the same cartridge can be loaded with different charges.

・Different cases and dampers are interchangeable.

・It is possible to flexibly adapt various holes to the same gun hole as the barrel throttle.

・Perfect gas plugging with reduced friction.

・Small-shot embedding in Watt material makes Watt and charge smaller. and can be separated more easily.

-Small wattage range.

・Less recoil.

・It must be a damping system that can recover energy.

In order to better understand the main features of this invention, the following description is supplemented and the drawings are incorporated into this description. Further details, which accompany the description but are not limited by the drawings, are included below.

Drawing description FIG. 1 is a side sectional view of a preferred embodiment of the invention.

Figure 2 is a plan view and a side sectional view of the case.

FIG. 3 is a plan view and a side sectional view of the damper shutter.

FIG. 4, FIG. 5, and FIG. 6 show the above-mentioned FIG. 1 according to another embodiment of the invention, 3 is a diagram similar to FIGS. 2 and 3; FIG.

Description of examples Referring to the above drawings and following the numbers in the top left drawing, we can see that there are two independent elements viz. It consists of a case 1 and a damper shutter 8, but how does the cartridge work? You can understand what is being carried out. Once assembled, the two elements form a cart Become Ridgewood itself.

Case 1 has a cylindrical appearance, with a plurality of flaps connected at the bottom and walls of the case 1. 3 is formed with a plurality of holes for accommodating the flaps 7.

When the flap 7 is folded, it is accommodated in the hole, and the case 1 is closed as a whole. It has a cylindrical appearance.

The case has a smooth inner wall that opens outwardly in the form of a frustocone. bottom a In other words, the base body 4 has a truncated conical shape 17, and the inner wall terminates in a ring which becomes the base of the case itself. terminated with a shaped ring.

The lower part of the case has a ring-shaped groove connecting the damper shelter 8 to the main part. The central portion has a truncated conical shape. substrate or base The central part of the wall, which acts as the bottom of the body 4, is identical to the membrane 5 made of the same material as the case. It houses a valve consisting of two closed holes occupying the same space. of the valve The upper hole is cylindrical or polycylindrical, and the lower hole is truncated conical or close to it. take shape. Membrane dimensions and thickness may be varied as desired.

The membrane is replaced by a cap that can slide on a pressurized seat and acts similar to a membrane. It can also be replaced with a hole through which the air throttle can be adjusted as needed. This is noteworthy.

The damper gelter 8 is defined by a bellow-shaped wall 9 and also has a sin Urn-shaped profile with a slightly curved curve, with a chamber terminating in a curve to accomplish. Such a wall 9 may have a transverse shape acting as a bellows-shaped base or closure device. A projecting bottom supported on the face wall 12 and formed by joining the truncated conical shapes 11 and 12 to each other. has.

The same wall 12 has a convex bottom which joins the frustoconical shapes 11 and 13 together.

The top or edge 10 of the damper 8 is incorporated into a ring-shaped groove. groove is flat It has a double-lipped edge for high liquid tightness when supported on a surface. da In order to avoid that the pump 8 and case 1 remain connected, There are matching ring-shaped ribs, and they are easy to separate.

This invention eliminates all the disadvantages of current wood. To that end, we need two things. The raw material is selected and both elements are manufactured by injection molding or blow molding. Made of plastic, non-rigid or semi-rigid materials.

Once both elements of the wood are assembled, cartridge installation is possible.

When placed inside a cardboard case, the side flaps are inside its housing. It is folded into position and held in this position until the wattage comes out of the gun. Then w opens to act as a stabilizer or brake.

If the watt is placed inside the case and is stationary with respect to the powder charge. , the damper is bent and the air in the cartridge is compressed (such compression is (determined by the bellows length of the damper). In this position, the watts are It receives a shot charge and is prepared to fire.

Considering all of the above points, when the gun fires, the damper will hit the case wall and the gun. It acts by bending the material of the wall (Perot) in addition to the friction created by the

When the damper bellows are fully folded, the protruding cone of the damper base is Push the folded wall opposite the conical part of the case wall and press both conical parts. Transform until the shape fits. At that time, it is housed in the chamber 6 and compressed. The air reaches the pressure required to open valve 2, which injects a jet of compressed air. The compressed air is used to brake and convert energy into useful propulsion. Promote small shot charges that partially compensate for Gunthroat this valve If valve 2 is designed to open when it receives excessive pressure from the Use some of the energy stored while damping the impact of the shot charge. wattage, and the internal resistance to compression is reduced, making the wattage more effective. Allow the throttle to pass.

The cross-sectional wall of the case and the sealing wall of the damper have an uneven shape, so the Watt's rotation is The radial restriction on the axis of rotation can be reduced, and the small shot charge reduces the wattage. Passes through the throttle smooth and flat.

Furthermore, valve 2 can easily change the valve opening pressure or air mass and It can operate instantaneously or in a progressive manner as required. In these environments, the air It is easy to create a flow either immediately or gradually, so the final reduction required is It can weaken.

When Watt exits the gun, the flap will open.

The opening movement of the flap is assisted by air contacting the watt at a very high velocity. be done. Once the flap opens, the trajectory is stabilized and the smoke is maintained without stopping the wattage. Watt and small shot charge without distorting the trajectory of the small shot charge. Separates quickly and smoothly.

If the watt suddenly separates from the charge, the damping effect of the air will cause the shooter to It will fall nearby and you won't have to worry about whether the charge will hit the target or not.
