Quick-firing medium-calibre automatic gun.

摘要

The gun, the barrel (1) of which comprises at least seven chambers, is characterised in that it possesses a rotary star shaft (11) of intermittent movement, coaxial relative to the barrel (1) and designed to be capable of gripping the cartridges and driving them in rotation one by one, whilst allowing them to move there in translational motion, a fixed helical ramp (14) interacting with the base of the cartridges to combine with their intermittent rotational movement an intermittent translational movement within the star shaft, to ensure that they are transported as far as the firing station in the respective barrel chambers, a slide (4) with an alternating translational movement controlled by means of gas to ensure the intermittent driving of the barrel in rotation and mechanical means for synchronising the rotational movements of the star shaft with those of the barrel. <IMAGE>
