Abstract

859,793. Rotary pumps and motors. ZAHNRADFABRIK FRIEDRICHSHAFEN A.G. Sept. 25, 1957 [Sept. 25, 1956], No. 30104/57. Class 110 (2). In a rotary pump or motor of the n and n + 1 lobe type the internally-toothed ring 2 is axially displaceable relative to the inner rotor 1 by fluid output pressure acting on a movable bush 11 in opposition to a spring-loaded bush 12.
