Abstract
A recoil brake 10 for a gun includes a cylinder 11 and a piston 12 which is slidably mounted in cylinder 11, with braking force being supplied when piston 12 is extracted by the recoil movement of the gun barrel and presses hydraulic fluid through a narrow flow cross section. In order to be able to accommodate the recoil brake in an area protected against enemy fire or shrapnel, even if space is cramped, the structural length of the recoil brake is reduced by including a further piston rod in the form of a hollow cylinder which is disposed within cylinder 11 so as to coaxially surround the first piston rod 12. This second piston rod 13 is extracted only after the first piston rod 12 has reached its maximum extended position.
