Abstract

1,226,960. 960. Rotary pumps and motors. DUNLOP CO. Ltd. July 3, 1968 [July 8, 1967], No.31537/67. Heading F1F. A rotary positive-displacement machine, as described, a rotary sliding vane vacuum pump, comprising a rotor member 10 fixed to the shaft 7 of an electric driving motor 5 and eccentrically mounted within a cylindrical body portion 4 closed by end walls 2, 3, includes adjuster means to adjust the clearance between the end wall 2 and the adjacent end face of the rotor member comprising a hardened steel adjuster screw 13 having a part-spherical surface 14 and a hardened steel button 18 having a part-spherical surface 19 located in a central rotor member recess 17. To reduce the load imposed upon the rotor member in the event of deflection of the shaft 7, the edges of the vanes 11 slidably received in the rotor may be roughened and vapour blasted with the result that the crests between the grooves are rubbed down. A dry lubricant such as P.T.F.E. or graphite emulsion or molybdenum disulphide in a bonding agent may be used between the rotor member and end wall 2 or a layer of low friction metal, e. g. lead, lead/tin or lead/indium may be applied to the end face of the rotor member.
