Manage, be fixed with gas block on the gun barrel, the adjuster and piston of coaxial heart line, the rifle are installed in the gas block
Pipe is provided with gas port, and the adjuster is provided with air admission hole, regulation air chamber, and gap coordinates between the adjuster and gas block
There is a body, the body is provided with the air channel connected with the gas port and air admission hole, and the adjuster corresponds to gas port
Position on be additionally provided with the expanding chamber connected with body air channel, buffering is formed after gas port enters for powder gases.
Preferably, the air admission hole includes macropore and aperture, and the groove width of the body air channel is more than the hole of the macropore
Footpath.
Preferably, the gas port is inclined on gun barrel.
Preferably, the body is provided with boss, and the gas block is provided with groove and coordinated with boss, and body is circumferentially limited
Position.
Preferably, the quantity of the boss is two, and two boss are symmetricly set on the both sides of body.
Preferably, the section of the expanding chamber is in sector.
Preferably, the section of the regulation air chamber is rounded.
Preferably, the gun barrel is provided with the limit base to adjuster axial limiting.
Compared with prior art, the utility model has following beneficial effect：
1. double air chamber gas-guiding structures of the utility model automatic rifle have two air chambers, by adjuster and gas block
Between body is set, make two air chamber indirect communications, powder gases initially enter expanding chamber and form dilution buffer, enter back into tune
Solar term room, powder gases directly the washing away to adjuster air admission hole of HTHP can be reduced, effectively prevent adjuster air inlet
The drastically ablation in hole, makes automatic machine stable movement, ensure that the reliability and service life of full rifle；
2. the air admission hole of double air chamber gas-guiding structures of the utility model automatic rifle includes macropore and aperture, special type is met
Requirement in environment；
3. gas port is inclined on gun barrel in double air chamber gas-guiding structures of the utility model automatic rifle, effectively reduce
Powder gases directly washing away to expanding chamber, can also alleviate ablation of the powder gases to gas port, further increase complete
The reliability and service life of rifle.
