Abstract
A tear gas grenade having a pressurized CO container oriented with a top in the trajectory direction to a target area and in facing relation to a top-piercing component across a clearance of a tracking compartment therebetween, in the operation of which a fuel-produced gas expands to simultaneously urge the top-piercing component in descending movement puncturing the CO container and also sealing the tracking compartment against venting of the fuel-produced gas and, after a time interval of contraction of the fuel-produced gas, the CO pressure urges the top piercing component in ascending movement unblocking the puncture opening in a container top and also unsealing the tracking compartment, to thereby correlate the expulsive effect of the CO to the time interval of the sealed contraction of the fuel-produced gas contributing to a tear gas consequence adjacent or in the target area.
