Abstract

986,576. Silencing gaseous currents. GRUNZWEIG & HARTMANN A.G. Sept. 7, 1961, No. 32210/61. Heading F1B. In a silencer in which a pipe has a reduced cross-section region 29 forming the throat of a Venturi tube, an absorbtion silencer 32 is arranged downstream of the Venturi tube. The Venturi tube may have a rectangular or square cross-section so dimensioned that the average flow speed in the narrowest cross-section is between a quarter and a half of the speed of sound in the medium flowing in the pipe. In other embodiments the Venturi tube is formed by one or more drop-shaped bodies arranged in the pipe and the absorbtion silencer comprises a container either surrounding the pipe or having an inner wall forming a portion of the pipe.
