SUBSTANCE: impeller 16 for a vane pump has several receiving elements 18 of vanes to receive at least radially movable pump vanes. Between two adjacent receiving elements 18 there is a wall 22 of a chamber for formation of an injection chamber. The chamber wall 22 has an axially protruding rib 24 for limitation of movement of a position ring for radial displacement of a pump vane. The chamber wall 22 has the first wall area 32 for reliable acceptance of the appropriate pump vane in the receiving element 18. The chamber wall 22 has the second wall zone 34 for formation of thickness of the rib 24 for reliable adjacency of a tool for baking. The chamber wall 22 has the third wall zone 36 for formation of the increased volume of the injection chamber.

EFFECT: development of an impeller for a vane pump, which will be easily manufactured and have an increased injection volume with the same structural volume.
