Abstract
A device for quickly stopping a remote controlled automatic cannon having a breech block which can be moved by means of an endless control groove in an essentially rotationally symmetrical control roller, with each region of the control groove being associated with a respective function step within the firing cycle of the cannon. The device includes an element which rotates in dependence on the control roller and is provided with a stop abutment which is associated with a region of the control groove; and a control piston, which corresponds with the stop abutment, and which, during operation, can be moved axially, by propellant gases developed during firing of the cannon, so that one free end of the piston moves out of the circular path of movement of the stop abutment against a return force, and thus from a blocking position with respect to the stop abutment, into a release position with respect to the stop abutment.
