Therefore, the pressure in the pump chamber 6 can be gradually increased before the pressure in the pump chamber 6 opens to the discharge port 11, and a rapid pressure fluctuation in the pump chamber 6 can be suppressed.
- the working fluid in the pump chamber 6 is pushed toward the outer peripheral side by the centrifugal force due to the rotation of the rotor 2, and the working fluid Lighter air accumulates on the inner circumference side.
- the air accumulated on the inner peripheral side is mainly guided to the pump chamber 6 at the rear in the rotational direction via the inner notch 26.
- the pressure of the pump chamber 6 is not sufficiently increased because the air is compressible.
- the pump chamber 6 communicates with the discharge port 11 in a state where the pressure in the pump chamber 6 is not sufficiently increased, so that the pressure in the pump chamber 6 rapidly increases and the pressure fluctuation increases.

- the inner notch 16 is always disposed inside the outermost peripheral portion of the raised portion 2 a of the rotor 2 regardless of the rotation angle of the rotor 2.
- the outer notch 15 opens in the pump chamber, and then the inner notch 16 opens. Accordingly, when air is mixed in the working fluid and the rotation speed of the rotor 2 is particularly high, the air is pushed toward the outer peripheral side prior to the air displaced toward the inner peripheral side by the centrifugal force due to the rotation of the rotor 2.
- the working fluid is guided to the pump chamber 6 at the rear in the rotational direction via the outer notch 15.
- the high-pressure working fluid is guided to the pump chamber 6 at the rear in the rotation direction. Accordingly, the pressure in the pump chamber 6 is gradually increased before the pump chamber 6 communicates with the discharge port 11, so that rapid pressure fluctuation due to insufficient pressure increase in the pump chamber 6 can be suppressed. .
- the outer notch 15 is formed radially outward from the raised portion 2a of the rotor 2, the air pushed between the raised portions 2a on the inner peripheral side by the centrifugal force due to the rotation of the rotor 2 is introduced to the pump chamber 6 at the rear in the rotational direction. Therefore, the working fluid can be positively guided to the pump chamber 6. Therefore, since the pressure in the pump chamber 6 can be more reliably increased until the pump chamber 6 communicates with the discharge port 11, rapid pressure fluctuations in the pump chamber 6 can be suppressed.
- the pump performance is maintained even when the vane pump 100 is operated in a state where the air content in the working fluid is higher and the rotation speed of the rotor 2 is higher. can do.
- an inner notch 16 is provided radially inward from the outer notch 15, and the inner notch 16 has a shorter rotational direction length of the rotor 2 than the outer notch 15, so that the outer notch 15 communicates with the pump chamber 6 first. Can do. Therefore, the working fluid pushed toward the outer peripheral side by the centrifugal force due to the rotation of the rotor 2 can be actively guided to the pump chamber 6.
- the inner notch 16 communicates with the outer notch 15 immediately before the pump chamber 6 communicates with the discharge port 11, the amount of working fluid that can be introduced into the pump chamber 6 is increased, and the pump chamber 6 is further increased in pressure. Can be planned.
- the inner notch 16 is formed inside the outermost peripheral portion of the raised portion 2a of the rotor 2, air is mixed into the working fluid guided from the discharge port 11 to the pump chamber 6 via the inner notch 16.
- the air is supplied into the air that is pushed away between the adjacent raised portions 2a in the pump chamber 6 by the centrifugal force generated by the rotation of the rotor 2, the pressure in the pump chamber 6 is unlikely to fluctuate. Therefore, pressure fluctuations in the pump chamber 6 can be suppressed.
- variable displacement vane pump may be used.
- the inner notch 16 is provided on the inner peripheral side of the outer notch 15, but the inner notch 16 may not be provided.
- a total of two notches of the outer notch 15 and the inner notch 16 are provided, but three or more notches may be sequentially arranged in the radial direction of the rotor.
