Abstract
A recoil brake for a gun includes a brake cylinder in which a piston is slidably arranged. As the piston moves when urged by the recoiling mass, it displaces fluid through a narrow flow cross section to thus brake the recoiling mass. The piston rod and the brake cylinder define a brake chamber formed therebetween. The recoil brake is provided with a heat equalization device that includes a heat equalization chamber which is bounded by a spring-tensioned heat equalization piston. An indicator element is coupled to the heat equalization piston for detecting an operating condition (the temperature of the hydraulic fluid) of the recoil brake. The heat equalization and indication device is a self-contained, modular unit releasably connected to a rearward end of the brake cylinder and forming an axial extension thereof. The heat equalization and indication device further has an impact plate bounding the heat equalization chamber and the brake chamber.
