Patent ID: 10718587

Abstract:
The invention relates to a silencer device for a firearm, in particular for a rifle or another long or short firearm and a silencing method, which comprises: at least two closing flaps (10) mounted across the axis on the barrel of the firearm in order to provisionally seal the barrel after the ammunition has passed and to prevent the passage of the combustion gases and the sound wave towards the mouth of the barrel when a shot is fired, an actuation unit (2, 4, 5) including at least one opening (1, 3) made in the barrel of the firearm upstream from the closing flaps (10) to form a gas intake (1, 3) moving a control mechanism (6-9); the control mechanism (6-9) including at least two arms of an amplitude lever (8, 12) pivotably mounted on pivots (7) attached to the barrel, each arm of the amplitude lever (8, 12) being coupled to either one of the closing flaps (10), the actuating unit (2, 4, 5) engaging with the control mechanism (6-9) to allow a transverse movement of the closing flaps (10) between an open position in which the flaps (10) allow ammunition to pass towards the mouth of the barrel and a closed position preventing the passage of the combustion gases and the sound wave after the ammunition has passed, and an exhaust unit (11, 21-27) including at least one exhaust pipe (11, 21) arranged on the barrel upstream from the closing flaps (10) in order to redirect the combustion gases and the sound wave and allow them to be discharged from the barrel.
