ABSTRACT:
A cooling arrangement for the gun barrels of firearms, in particular automatic firearms and high-performance machine cannons. The arrangement includes radially outwardly directed cooling pasageways between the individual projectile chambers provided in the drum in the region of the end portion of the gun barrel axially adjoining the drum, and which are connected with a main passageway in the hollow-bored longitudinal barrel axis for the central cooling medium infeed. Connected to the nozzles of the radially directed passageways, which nozzles extend essentially in parallel with the longitudinal axis of the drum, closure members are interposed in the radial cooling passageways which automatically open and close in dependence upon the drum position and only during firing, whereby the outlet openings of the nozzles positioned in the axial end surface of the drum and, during rotation of the drum, will presently openly communicate for a short period of time with the associated end portion of the gun barrel.
