    摘要: The invention resides in a rotary machine in which an electromagnetic spherically shaped armature and a pump impeller being enclosed in a casing are born, as a unit, by a frusto-spherical bearing of which the convex (or ball) part rotates, and in which frictional rotatable seal means are carried by an annular wall extending inwardly of the casing between armature and impeller supports the fixed bearing part and sealing means which isolate the spaces in which run the armature and the impeller respectively.
