An absorbing plate(18) is assembled with an exhaust valve(12), which is stretched along the return spring(9). The first shock absorber(35) is arranged on the return spring side. An app.(19), which introduces the sliding movement of the(12) in the vertical direction, is established between the exhaust valve and the trigger(28). (19) has a hole larger than the diameter of(12), to provide elasticity and to prevent alignment of the exhaust valve with the hole. The firing shock is greatly reduced by the absorbing plate and the first shock absorber. This app. prevents firing, when the rifle is accidentelly dropped. |
