A conduit (6) between the nozzle and throttle leads to a medium chamber (7), the volume of which is periodically adjusted. The storage container may be subjected to gas pressure via a conduit (9), or may have a movable spring-loaded or gas-pressurised wall. The throttle has an adjustable pressure drop. The volume of the medium chamber may be adjusted by a magnet, a hydraulic system or a compressed air vibrator. The storage container contains a vibrating ram, projecting into a sleeve. The ram and sleeve from a throttle gap (4), and the medium chamber. The ram is retained by a spring, the pre-tension of which may be adjusted via a spindle.</p> |
