ABSTRACT:
In a fire limiter for automatic firearms with hammer blow detonation, a pawl (38) is supported pivotally directly on a bearing on the hammer arranged eccentrically to the latter's pivoting axis (1). The pawl transfers essentially the entire striking motion of the hammer to a wheel ratchet, which at every shot rotates by one tooth and is held in any given position by a spring-loaded stop pawl. The wheel ratchet is provided with a cam which, after a predetermined number of intermittent stops, activates a fire disconnector which preferably comprises a trip-releasing catch (26), supported pivotally on the trigger (16), and a sear (12), supported pivotally on the same shaft (14) as the trigger (16). The catch (26) initially latches the sear (12) and is pulled away from the sear (12) by the wheel ratchet, whereby the sear is released to drop into a detent (11) on the hammer (2).
