A hammer assembly of the automatic mechanism of a firearm, comprising a breech (4) that is pushed towards the barrel (3) by a return spring (6). On the breech (4) and/or in the breech case (3) a hammer carrier (10) is arranged in a sliding way that is pushed towards the breech by a striking spring (13). The hammer carrier (10) carries a hammer (11). The hammer (11) is arranged on the hammer carrier (10) movably between the front end position and the rear end position wherein between the front and rear end positions of the hammer (11), there is a play (F). The hammer (11) is pushed to the front end position by the hammer spring (12).

13ABSTRACTAn automatic action assembly of a firearm, comprising a barrel (2) with a slidingcartridge chamber (1) arranged in a sliding way between the front and rear deadcenter. The movement of the sliding chamber (1) is delimited by at least one firststop (3) on the sliding chamber (1) and a corresponding at least one second stop (4) connected to the barrel (2). Between the first stop (3) and second stop (4), there is a play (A). In the rear part of the sliding chamber (1), a breech block (5) is lockably connected at the end of which a breech block (5) carrier (6) isio mounted in a sliding way. The breech block (5) carrier (6) is pushed by a returnspring (7) towards the barrel (2). The breech block (5) is fitted with an unlocking mechanism for delayed disconnection of the breech block (5) from the sliding chamber (1). Fig. 1Date Recue/Date Received 2020-11-03
F41A 3/10 - Culasses à bloc ou à coin, c.-à-d. dont le mouvement principal d'ouverture est transversal à l'axe du tube de l'arme avec un mécanisme à bloc de culasse coulissant, p. ex. verticalement
F41A 3/44 - Mécanismes à verrous semi-libres, c.-à-d. à verrous montés mobiles sur le bloc de culasse, ou sur le tube de l'arme ou la boîte de culasse munis d'éléments de verrouillage coulissants, p. ex. de billes ou de galets
The firearm comprises a firearm housing (1) connected to the barrel assembly (2), a firearm breech (3) mounted in the housing (1) and connected to a spring for forcing the breech (3) to its initial shooting position, a tensioning lever (11), a tensioning lever (11) carrier (4) that is connected to the tensioning lever (11) and arranged for common linear movement in the axial direction of the firearm with the tensioning lever (11) in and against the shooting direction. The tensioning lever (11) contains the first latch (6) and lever part (7) wherein the first latch (6) is arranged for controlled movement by means of manual control of the lever part (7) from the first position - shooting position, wherein the first latch (6) is engaged with the barrel assembly (2), fixing the tensioning lever (11) to the barrel assembly (2), to the second position, wherein this engagement is disconnected and the tensioning lever (11) can move in the said axial direction against the shooting direction. The carrier (4) comprises the second latch (5) arranged in such a way that when the first latch (6) is in the said first position, the second latch (5) is out of engagement with the breech (3), so the breech (3), during its movement against the shooting direction caused by the shot, is not connected to the carrier (4), and when the tensioning lever (11) is outside the shooting position and touches the breech (3) at the same time, the second latch (5) is in engagement with the breech (3) and the tensioning lever (11) is thus fixed to the breech (3). The carrier (4) is further arranged for controlled movement in the said axial direction by means of manual control of the lever part (7 ).
