Abstract
754,984. Rotary pumps, engines and meters. LIQUID CONTROLS CORPORATION. Aug. 4, 1954 [Aug. 14, 1953], No. 22641/54. Class 110(2) A rotary positive displacement device for liquids such as a pump, meter, motor, compressor or blower comprises a blocking rotor 40 mounted in a casing 20 so as to define therewith inlet and outlet chambers 28, 29, displacement rotors 50, 60, each comprising a hub 61 and a radially-extending blade 62, mounted in said chambers respectively and means for connecting all said rotors for simultaneous rotation; the blocking rotor being provided with opposed recesses to allow the blades to sweep therethrough and the hubs being arranged in close proximity to the path swept by the blocking rotor in order to provide a seal therewith during a portion of its revolution. The rotor 40 is journalled in ball or sleeve-type bearings 45 which are seated in sockets 46 formed in the end plates 21, 22 of the casing. The rotor may be made from stainless steel and welded to a hub of like material: The rotor is preferably open at both ends and filled with liquid. The bearings are enclosed by cover plates 80, 81 which are bolted to the casing; the space between the cover and end plates being filled with a lubricant. The converse portions 41 of the rotor are serrated in order to form a labyrinthine capillary seal with the wall 24 of the casing; the edges 57 of the rotors 50, 60 being likewise serrated, if so desired. The shaft of the rotor 40 is coupled to a shaft 85 which is journalled in a sealed bearing 86 and is connected through gearing 87, 88, 89 to a counter 90 embodying an adjuster 92 (see Fig. 2, not shown)..
