Cooling device for cooling combustion gases from recoilless anti-tank weapons

Cooling device for cooling combustion gases from a rocket motor in an anti-tank weapon, preferably of the hand-held recoilless rocket weapon type for firing of a rocket/projectile in tight spaces in which harmful sound pressure is generated, which cooling device comprises a coolant reservoir containing a coolant, arranged such that the coolant, in response to a pressure increase in the rocket motor upon firing of a propellent powder charge, is transferred from the coolant reservoir to the combustion gases in the gas outlets of the rocket motor, wherein the coolant reservoir constitutes an integral part of the rocket motor, the coolant reservoir being connected by at least two gas inlets to a combustion chamber arranged in the rocket motor, for pressurization of the coolant, and by at least two coolant outlets to a rocket motor nozzle disposed in the rocket motor, for transfer of coolant from the coolant reservoir to the rocket motor nozzle during the whole or parts of the combustion process in the combustion chamber.
