Abstract

811,612. Silencing gaseous currents. SULZER FRERES S. A. July 12,1957 [July 27, 1956], No. 22226/57. Class 7(2) [Also in Group XXVI] A rotary compressor comprises a sound reflecting surface facing the intake opening and spaced therefrom, and laminar parts . disposed at a distance from one another in the region of the intake opening, the portions of the laminar parts extending towards the sound reflecting surface being inclined with respect to it. Sound emerging from the intake 4, Fig. 1, of a centrifugal compressor is directed by the inclined parts 8 of guides 6 so that it impinges on a sound-reflecting surface 7 at an angle, and is reflected from the surface and then undergoes successive reflections between the guides 6, as shown in Fig. 2, so that it is dissipated at least partly by the soundabsorbent linings of the surface 7 and guides 6. The surface 7 is bent over at the ends 11 to assist the reflecting action.
