ABSTRACT:
An air cannon for removing cakes of flowable material and clearing clogged areas of flowable material in silos, heat exchanger and lines has a pressure container for storing compressed air and a pressure source connected to the pressure container. An outlet valve is connected to the pressure container. An outlet jet is connected to the outlet valve. The outlet valve has a valve housing and a piston, wherein the valve housing has a guide in which guide the piston is axially slidable. An annular channel is formed between the valve housing and the guide. The annular channel is connected to the pressure container and, in the open position of the outlet valve, forms a cylindrical opening that opens into the outlet jet. The piston has a forward end face facing the outlet jet and having an annular valve sealing surface. The rearward end face of the piston is subjected to a suddenly releasable closure pressure. A pressure present in the outlet jet acts on the area enclosed by the annular sealing surface, and a pressure of the pressurized container acts on the area surrounding the annular sealing surface.
