    • F04C2/101—Rotary-piston machines or pumps of intermeshing-engagement type, i.e. with engagement of co-operating members similar to that of toothed gearing of internal-axis type with the outer member having more teeth or tooth-equivalents, e.g. rollers, than the inner member with a crescent-shaped filler element, located between the inner and outer intermeshing members

Definitions

  • the end faces 10, 11 of the filler parts 7a, 7b are partially cylindrically curved, the cylinder axis or axis of curvature running parallel to the axis of the gearwheels 3 and 5 and to the "longitudinal axis" of the support element 13.
  • the ring gear 3 has radially through bores 3a which serve for the inflow and outflow of the flow medium conveyed through housing channels, which are not identified in any more detail.
