Abstract:
1. A delivery unit having a drive shaft ( 2 ) and a rotor ( 3 ) which is driven by the drive shaft ( 2 ) and is arranged rotatably in a stator housing ( 4 ), the drive shaft ( 2 ) having an oblique sliding piano ( 5 ) which interacts with the rotor ( 3 ), is formed on a shoulder ( 6 ) of the drive shaft ( 2 ) and allows the rotor ( 3 ) to tumble with a rotor axis ( 7 ) about a drive axis ( 8 ) of the drive shaft ( 2 ), the rotor ( 3 ) having a toothing system ( 12 ) on an end side which faces away from the drive shaft ( 2 ), which toothing system ( 12 ) meshes with a toothing system ( 13 ) which is formed on the stator housing ( 4 ), working spaces ( 1 . 4 ) being formed between the toothing system ( 12 ) of the rotor ( 3 ) and the toothing system ( 13 ) of the stator housing ( 4 ), which working spaces ( 14 ) can be filled via an inflow ( 15 ) and can be emptied via an outflow ( 16 ), characterized in that one of the inflow ( 15 ) and the outflow is provided in a channel ( 20 ) of the drive shaft ( 2 ) and the other of the inflow and the outflow ( 16 ) is provided on the shoulder ( 6 ) of the drive shaft ( 2 ), characterized in that the outflow ( 16 ) is of arcuate configuration or includes a plurality of outflow openings which are arranged arcuately, characterized in that the oblique sliding plane ( 5 ) is of circular configuration, the inflow ( 15 ) being arranged in one circle half and the outflow ( 16 ) being arranged in another circle half of the oblique sliding plane ( 5 ), and characterized in that at least one separating web ( 21 ) is provided between the inflow ( 15 ) and the outflow ( 16 ).
