Abstract

145,501. Daimler-Motoren-Ges. June 20, 1918, [Convention date]. Drawings to Specification. Movable-abutment type. - Rotary blowers, especially the Roots'-blower type, are adapted to be driven at high speeds from 2000 to 20000 revolutions per minute, the general shape of the parts being unaltered. The gear wheels are rigidly connected to the pistons in order to prevent any relative movements of the parts.
