Claims
- 1. An internal-gear machine comprising: a casing: an internally toothed annular gear mounted rotatably in the casing; an externally toothed pinion rotatably disposed within the annular gear and meshing with a portion of the annular gear, a clearance being defined between said pinion and the remaining portion of the annular gear; a generally sickle-shaped filling member disposed in said clearance and divided along a substantially circumferentially extending surface, thereby providing first and second filling member portions having end faces of a convexly curved configuration towards the intake side of the casing, the axis of the convex curvature extending substantially parallel to the axis of rotation of said pinion; and a support element extending axially through said clearance between the annular gear and the pinion and fixedly connected only to one wall of the casing, the support element providing a support surface against which said filling member portions bear slidably in a substantially radial direction and pivotably about a pivot axis extending at least substantially parallel to said axis of rotation of the pinion.
- 2. A machine as set forth in claim 1 wherein said casing defines therein a chamber having a radially inwardly facing circular surface and wherein said annular gear has an external bearing surface co-operating with said circular surface for rotatably mounting said annular gear.
- 3. A machine as set forth in claim 1 wherein said support element is in one piece with said wall of the casing.
- 4. A machine as set forth in claim 1 wherein said support surface is at least substantially flat.
- 5. A machine as set forth in claim 1 in the form of a pump.
