摘要： A firing system for a large-caliber weapon includes a firing pin displaceable into a position of rest, an armed position and a firing position; a spring urging the firing pin into the firing position; a follower affixed to the firing pin; and a rotatably supported control cam having a cam track. The spring urges the follower toward the cam track. The cam track has first, second and third consecutive cam track portions. The first cam track portion is shaped such that upon rotation of the control cam the firing pin is moved into the armed position by a cooperation between the follower and the first cam track portion. The second cam track portion is shaped such that upon continuing rotation of the control cam the firing pin is allowed to be accelerated by the spring into the firing position. The third cam track portion is shaped such that upon rotation of the control cam the firing pin is returned from the firing position into the position of rest by a cooperation between the follower and the third cam track portion. Further, an external drive is provided for rotating the control cam. An actuator operates the external drive for rotating the control cam through one cycle to effect consecutive cooperation between the follower and the first, second and third cam track portions.
