The two smooth running gears help to ensure excellent intake behaviour. In the radial direction, the gear chambers are closed by gear meshing and the filler piece. In the axial direction, the axial plates seal the pressure chamber with the minimal possible gap. This design minimizes volume losses and increases efficiency. When the gears rotate, the tooth heads enter the gaps between teeth and displace the pressure fluid. 2
