Gas piston and weapon

Abstract

The invention relates to a gas piston for a weapon, which is characterized by a spring introduced in the gas piston and a plunger, which engages on one end of the spring, wherein the spring is supported by the other end at the end of the gas piston opposite the plunger. This gas piston can be a component of a gas piston assembly having a counter piston, which is for use in a weapon. The gas piston or the plunger is supported e.g. on the weapon housing. With the special construction of the gas piston or the gas piston assembly formed with same, the gas piston can be transferred from a working position into a resting position within a weapon housing of the weapon.

Claims

1. A gas piston of a weapon, the gas piston comprising: a housing having a first end, a second end opposing the first end, and a perimeter extending between the first end and the second end and defining a channel; a spring disposed in the channel of the housing, and supported and compressible against the first end of the housing; and a plunger disposed at least partially in the channel of the housing and engaging one end of the spring, the plunger including a base member positioned between the spring and the second end of the housing and an extension member extending out of the housing at the second end of the housing when the gas piston is in a resting state.

2. The gas piston according to claim 1, further comprising a locking ring coupled to the second end of the housing.

3. The gas piston according to claim 2, wherein the gas piston is a modular assembly.

4. A gas piston assembly of a weapon, the gas piston assembly comprising an opposing piston and the gas piston according to claim 1.

5. A weapon comprising at least one gas piston according to claim 1.

6. The weapon according to claim 5, further comprising a weapon housing, wherein the plunger of the gas piston is supported in the weapon housing.

7. The weapon according to claim 6, further comprising a closing spring sleeve, wherein the plunger of the gas piston is configured to engage the closing spring sleeve.

8. A weapon comprising the gas piston assembly according to claim 4.

9. The weapon according to claim 8, further comprising a weapon housing, wherein the plunger of the gas piston is supported in the weapon housing.

10. The weapon according to claim 9, further comprising a closing spring sleeve, wherein the plunger of the gas piston is configured to engage the closing spring sleeve.

11. The weapon according to claim 6, wherein when a gas pressure on the gas piston is below a spring pressure of the spring, the spring moves the gas piston into its starting position in cooperation with the plunger supported on the weapon housing.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The invention will be explained in more detail with the drawing on the basis of an embodiment.

(2) In the drawings:

(3) FIG. 1 shows a gas piston assembly according to the prior art in the installed state,

(4) FIG. 2 shows a gas piston according to the invention as a modular assembly,

(5) FIG. 3 shows the gas piston from FIG. 2 in the resting state,

(6) FIG. 4 shows the gas piston from FIG. 2 in the working position.

DETAILED DESCRIPTION

(7) The present invention (FIG. 2) provides for the use of a gas piston 11 which comprises a spring 12. This can be designed as a compression or helical compression spring. The compression spring 12 is incorporated in the gas piston 11. The gas piston 11 has a plunger 13 at a first end 11.1, which is rearward when viewed in the firing direction. This engages one end 12.1 of the compression spring 12. With the other end 12.2, the compression spring 12 is supported on the housing end 11.2 of the gas piston 11 opposite the plunger 13. A locking ring 14 serves to hold the structure or gas piston 11 together as a modular, unitary assembly.

(8) FIG. 3 shows a gas piston assembly 10 having the gas piston 11 installed in the weapon housing 4. The gas piston assembly 10 is shown in the resting state. The gas piston assembly 10 comprises the opposing piston 2 and the gas piston 11 having the built-in compression spring 12 and the plunger 13. When extended, the plunger 13 is supported on the weapon housing 4. The rear end 11.1 of the gas piston 11 engages the closing spring sleeve 6 of the weapon 5. A gas bore 2.1 in the opposing piston is directed directly at the gas piston 11. The gas bore 2.1 should preferably be introduced in the opposing piston 2.

(9) FIG. 4 shows the gas piston assembly 10 in the working position. The gas produced during the shot is fed to the gas piston 11 via the gas bore 2.1. This gas pressure causes the gas piston 11 to move. This moves the closing spring sleeve 6 against the firing direction. At the same time, the compression spring 12 within the gas piston 11 is compressed and tensioned by the plunger 13. If the gas pressure G falls below a value which is below the pressure of the compression spring 12, the compression spring 12, in cooperation with the plunger 13, which is supported on the weapon housing 4, places the gas piston 11 in its starting position. The closing spring sleeve 6, which rushes forward later in time, can move forward unhindered. Bouncing is avoided.

(10) If closing spring sleeves are provided on both sides of a closure (not shown in detail), two gas pistons or two gas piston assemblies are to be introduced into the weapon housing 4.

(11) However, the use is not limited to a self-propelled weapon if an externally driven weapon uses the gas pressure of the weapon for various weapon functions.
