摘要：A stator-rotor assembly wherein rollers are used to form the internal teeth of the stator. The rotor has one less tooth than the stator and cooperates in gear relationship with the internal teeth of the stator. The stator has a plurality of cylindrically shaped pockets each containing a cylindrical roller. Each pocket is covered with a crushable porous coating to a thickness of X units. The radius of the pocket is R units and the radius of the rollers is equal to or greater than R-X units and less than R units. Each roller crushes the coating at spaced locations to trap fluid between the rollers and the pocket. The rotor has an average diameter that interferes with the tangent circle of the stator-roller assembly.
