Abstract

223,914. Akt.-Ges. Brown, Boveri, et Cie. Oct. 27, 1923, [Convention date]. Regulating or controlling; casings.-Springs are employed to prevent chattering of diffuser blades in rotary compressors. The spring may be a strip spring or, as shown in Fig. 2, a spiral spring c pressing on the lever f of the blade a, the root of which is held in a ball bearing d. In another modification the part e of the controlling rings acts resiliently on the blade lever f. In another modification a stretched band is arranged round the ring and under pegs on the blade levers.
