ABSTRACT:
A device for automatically producing periodical impulse changes in a pressure line is provided with an elastic intermediate member impacted by a control pressure. Pressurizing the exterior of the intermediate member produces a pulsating flow of the fluid in the pressure line, obviating the use of control members, flaps, etc. In a preferred embodiment, the required control pressure is drawn from a bypass in the pressure line. The present invention may be put to Advantageous use in numerous fields in pneumatic and in process engineering.
