Abstract
An ejection device in the form of a chaff cartridge for dipoles for aircraft defense, through disorientation of the hostile aircraft cannon radar. The ejection device allows for the dipoles to be completely ejected and wherein, after the ejection, the individual dipoles are uniformly dispersed to provide for the formation of a homogeneous cloud. In order to obtain the foregoing pistons of the device are provided with sealing rings, and include guide surfaces which extend in the axial direction of the shell and which conform to the shell. Advantageous hereby is the uncomplicated and inexpensive construction of the pistons from sprayed plastic material parts, and wherein the sealing rings additionally serve as tolerance compensators between the otherwise expanding shell with regard to the pistons.
