Abstract (en)
[origin: WO2009121471A1] The invention relates to a pump, particularly a vane pump, having a rotor comprising radial vane slots, which are provided for guiding vanes that can be extended from the vane slots radially to the outside in the direction of a stroke contour in order to effect suction in at least one suction region, and in order to effect pressurization of a working medium in at least one pressure region, which is connected to a pressure outlet, and further having a plurality of bottom vane supply regions. The invention is characterized in that a start bottom vane supply section having a start bottom extension section has a self-contained volume as long as the vane is, or the vanes are, not yet extended in the start bottom vane extension section.
