VACUUM PUMP OF VEHICLE FOR REDUCING OPERATION NOISE |
| 摘要 |
A vacuum pump of a vehicle for reducing operation noise may include a rotor rotating in a space defined by a housing formed in a pump body at an eccentric position relative to a center of the space, a vane installed to the rotor to rotate eccentrically in the space, and an oil outlet passing through the pump body and formed at a predetermined height above a lower limit of the space such that, when lubricant in the space is discharged in a pressurized state by the vane, the lubricant is not reintroduced back into the space by gravity. |

1. A vacuum pump of a vehicle for reducing operation noise, comprises:
a rotor rotating in a space defined by a housing formed in a pump body at an eccentric position relative to a center of the space; a vane installed to the rotor to rotate eccentrically in the space; and an oil outlet passing through the pump body and formed at a predetermined height above a lower limit of the space such that, when lubricant having been introduced into the space is discharged in a pressurized state by the vane, the lubricant is not reintroduced back into the space by gravity. |
