ABSTRACT:
This invention relates to arrangements for the prevention or minimization of over-pressures due to sudden interruptions in the flow of a compressible fluid which are caused by an obturator such as an electrical valve along a main gas pipe and more particularly relates to such arrangements which consist of a pressure regulator and reducer mounted on the said main pipe upstream of the obturator and the response time of which is longer than that of the said obturator, a venturi which communicates with that section of the main pipe which is situated between the obturator and the regulator and reducer, and a buffer reservoir which is in permanent communication with the said section of main pipe via the venturi. According to the invention the regulator and reducer also forms a venturi.
