Abstract
800,211. Rotary pumps and motors. BREWER, C. E. Aug. 31, 1956 [Sept. 1, 1955], No. 25139/55. Class 110 (2). In a rotary pump or motor of the Rootsblower type, one of the rotors 17 is provided with side flanges 22 having exhaust ports 23, the casing 10 being provided with inlet and exhaust ports 13, 14 communicating with inlet and exhaust ports 25, 26 respectively which are disposed in the cover-plates. One of the side flanges may be detachable or alternatively each rotor may be provided with a flange at one end only. One or more lobes 20 may be detachably secured to the rotor by spring clips or dovetailed thereto and locked in position by dowels or pegs. Each lobe may be made of non-ferrous or other material having a low coefficient of friction or provided with inserts of such material. The ports 13, 14 may be disposed in the coverplates and provided with non-return valves as desired.
