Abstract
521,031. Rotary pumps. FILLIOL, L. A. D. Dec. 13, 1938, Nos. 36309 and 36310. Convention dates, Dec. 21, 1937, and Nov. 15, 1938. [Class 110 (ii)] The teeth of gear wheel pumps, of both internally and externally meshing types, are formed of cylindrical rollers 1 mounted in cages 5 upon the rotors 6. The rotors are interconnected by ordinary gear wheels 8 and these may be adapted to act also as a lubricating pump to supply oil to the rollers when the main pump is being used to pump gases. The cages may be formed, Fig. 9, to engage as toothed wheels. In this case, the rollers provide only sealing contact with the stator. The rollers may be arranged to mesh with intervening portions of the cages as shown in Fig. 11. The stator may be made in two parts united by bolts 22, Fig. 4. This construction permits the taking up of back lash. The cages are frictionally secured upon the rotors or the rotors may be formed of several closely wound spring coils which grip the driving shaft and the inner surface of the cages.
