Abstract
The invention relates to an apparatus for the intermittent production of a pressure wave in hoppers or other containers. For release of a pressure wave, a valve which, according to the invention, consists of a simple valve disc (10) between a storage housing (1) and an outlet pipe is opened suddenly. The opening of this passage by raising the valve disc (10) from the pipe (5) takes place in the usual manner by venting a pressure chamber (7) adjoining the valve disc (10). <IMAGE>
