FIELD: engines and pumps.
SUBSTANCE: invention relates to a vane pump with at least one pump stage (14). This pump stage (14) has impeller (18) that is not rotatable on pump shaft (26). Along with pump stage (14), the vane pump is equipped with a pump located on shaft (26) without moving the clutch to pump shaft (26) in the pumped flow of the impeller pump by turbine wheel (32). This turbine wheel (32) forms the flowmeter sensor. Turbine wheel system (32) is designed in such a way, that the torque applied by the pumped stream to turbine wheel (32) is directed opposite to the torque imparted through pump shaft (26) to impeller (18).
EFFECT: invention is aimed at increasing the accuracy of flow detection.
