Mechanical servo trigger mechanism for automatic guns.

摘要

A mechanical servo trigger mechanism for automatic guns provided with a pressure ramp (1) for moving the weapon trigger (17) between a firing and a non-firing position. The ramp (1) is mounted in a parallel link connection (3) that is connected with a base plate (2) so that the ramp (1) is movable to an upper from a lower position by a further link means (4) biased by a spring (5) towards its upper position, and lockable in a cocked position by a spring-biased trigger locking hook (11) which is releasable by a trigger rod (12). A stop movable by an arm (6) is able to hold the ramp (1) in its upper position, which causes automatic firing of the weapon. Said mechanism can be cocked manually or automatically by a cocking rod acting on a first roller (9) provided on the further link means (4).
