The present invention relates to a vane pump which is capable of smoothly drawing in a working fluid and is drawn into a rotary chamber while minimizing damage of a vane or occurrence of noise, has an excellent performance in terms of flow and volume efficiency, and is capable of effectively reducing inner cavitation. To this end, the vane pump of the present invention is configured in a manner whereby the working fluid introduced into one side of the rotary chamber formed between an outer cam ring and a rotor is exhausted to the other side of the rotary chamber, wherein a through-slit extended along the circumferential direction of an outer cam ring is formed in a corresponding part of the outer cam ring corresponding to the side into which the working fluid is introduced. |
