Abstract
622,873. Rotary blowers. ANDREWS, T. D. H. April 10, 1947, No. 9534. [Class 110(ii)] The inlet port 10 of a Root's blower is shaped to divide the entering fluid into two streams which are gradually accelerated and directed to avoid shock losses; the delivering port 11 is similarly shaped, in reverse. Passages 13, 14 gradually decrease in cross-sectional area. The casing is constructed in three parts, as shown. The invention may be applied to the blower described in Specification 616,485.
