Abstract

879,067. Exhaust silencers. DUSTERLOH FABRIK FUR BERGWERKSBEDARF G.m.b.H., G. Jan. 28, 1960 [Jan. 28, 1959], No. 3104/60. Class 7(2). [Also in Group XXVI] A gear motor has its casing wall 3 provided with at least one circumferentially extending slot 4 for noise reduction purposes. The depth h of the parallel faces of each slot is not more than the width b and the faces then diverge towards the exit chamber 5. In another embodiment, Figs. 2, 3 (not shown), the slots a are formed between end faces of the rotors and bearing shields 19, 191, 20, 20<SP>1</SP> respectively, and apertures 22, 221, 23, 231 are formed in the casing wall adjacent the slots.
