As the gun rear end side of the slider 3 moves, the engaging convex portion 16b of the trigger 16 slides on the slope of the unattached recess 3a of the slider 3, and is pressed against the lower side of the gun. In this way, the trigger link locking portion 18b of the hammer iron 18 is disengaged from the hammer resistance engagement projection 16c of the trigger lever 16 . The hammer iron 18 is rotated in the clock direction (to the hammer 20 side) around the hammer iron shaft 18c by the spring force of the hammer iron spring 19, and returns to the position where it is engaged with the hammer 20.

Next, description will be made on the 12th and 22nd drawings. The slider 3 abuts against the slider retreat preventing portion 2a provided on the grip 2 by the slider locking portion 3b provided at the lower portion of the muzzle side of the slider 3, and stops the slider 3 from moving backward. The remaining gas remaining in the gas cylinder 33 is discharged from the muzzle side opening of the gas cylinder 33 to the atmosphere.

The automatic flushing air valve 29 is slid toward the rear end side of the gun by the reaction force of the compressed automatic cover valve spring 31. In this way, the automatic over-intake air valve 29 abuts the automatic cover air valve flange portion 29c and the automatic cover air valve gasket 30 of the automatic cover air chamber 25b, and is automatically covered. The gas valve gasket 30 is used to close the automatic valve opening portion 29a. In this state, in the same state as in the first drawing, the gas from the automatic rinsing air chamber 25b is stopped, and the automatic hood gas chamber 25b is in an airtight state.

Next, description will be made with reference to Fig. 13 and Fig. 23. The slider 3 starts moving toward the muzzle side by the spring force of the rebound spring 13. This forward movement causes the rear portion of the gas valve body 24 to be inserted into the gas cylinder 33, and the gas cylinder pressure receiving surface 33a in the gas cylinder 33 abuts against the rear end surface of the gas valve body 24 to stop.

The hammer 20 uses the spring force of the hammer spring 21 to rotate in the counterclockwise direction centering on the hammer shaft 20b, but the hammer iron stopper portion 20a of the hammer 20 abuts against the hammer iron stopper. In the portion 18a, the hammer 20 is stopped from rotating, and the hammer 20 and the hammer iron 18 are locked.

Next, the description will be made on Fig. 14. Based on the state of Figure 13, The user leaves the finger from the trigger 14, and the trigger 14 is rotated in the clock direction by the spring force of the trigger spring 15 around the trigger shaft 14a, and returns to the original position (state of Fig. 1).

The barrel latch 9 is moved back to its original position by the trigger 14, and is pushed upward by the upper front end 14b of the trigger 14. after that. At the point in time when the barrel case locking portion 9b of the barrel stopper 9 abuts against the barrel latch locking portion 8a of the barrel case 8, the barrel stopper 9 is locked.

Fig. 14 is a view showing the same state as that of Fig. 4. Therefore, when the bullet is fired, the actions of the fifth to the fourth steps are sequentially performed, and a series of operations can be repeated.

[Effect of the invention]

According to the present invention, the bullet emission air chamber and the automatic cover air chamber are separately provided, and the individual air chambers are provided with individual air valves, and the bullet emission air valve is actuated by the trigger of the barrel by the action of the trigger. When the valve is opened, the automatic valve is opened by the action of the hammer by the action of the trigger. Thus, the individual chambers or valves are independent of each other. Therefore, the size of the opening area of the individual gas valve, the length of the opening time, the ease of opening, and the like can be adjusted in design, and the degree of distribution of the gas pressure of the compressed gas can be easily grasped. Therefore, the adjustment of the bullet speed or the adjustment of the automatic overlay can be adjusted in design. For example, irrespective of the opening of the automatic overfill valve, by increasing the opening time of the automatic flushing valve or increasing the opening area, more compressed gas is sent into the inner barrel, which can speed up the firing rate of the bullet. .

Furthermore, the bullet emission and the automatic overlay timing can be individually adjusted, so that the automatic override operation is performed after the bullet is fired, and the design can be surely adjusted. In this way, it is easier to develop a design for an air gun that improves the accuracy of hits.

[Possibility of industrial use]

The present invention is applied to form an air gun having an automatic overlay mechanism.
