Abstract: An oil supply groove 12 in communication with a pump room 2A is formed above a bearing 2B of a housing 2, and an open air groove 14 in communication with an atmospheric air is formed at a position rotated around the bearing 2B by 90° from the oil supply groove. In a shank 3B of a rotor 3, a branch passage 11a branching from an oil passage 11 formed in its axial direction to the diametrical direction of the shank, and an open air passage 13 formed in the direction perpendicular to the branch passage are formed.Then, the branch passage and the oil supply groove communicate with each other, at the same time, the open air passage and the open air groove are arranged to also communicate with each other, and when the oil passage and the oil supply groove communicate with each other as the rotor stops, then an atmospheric air flowing in from the open air passage eliminates a negative pressure in the pump room, thereby the lubricating oil is prevented from flowing into the pump room in large quantities.An amount of the lubricating oil flowing into pump room at stop of the rotor can be reduced to prevent the vane from being damaged and an amount of the lubricating oil consumed due to rotation of the rotor can be controlled.

Abstract: An oil supply groove 12 in communication with a pump room 2A is formed above a bearing 2B of a housing 2, and an open air groove 14 in communication with an atmospheric air is formed at a position rotated around the bearing 2B by 90° from the oil supply groove. In a shank 3B of a rotor 3, a branch passage 11a branching from an oil passage 11 formed in its axial direction to the diametrical direction of the shank and an open air passage 13 formed in the direction perpendicular to the branch passage are formed. The branch passage and the oil supply groove communicate with each other while the open air passage and the open air groove are arranged to also communicate with each other. When the oil passage and the oil supply groove communicate with each other as the rotor stops, atmospheric air flowing in from the open air passage eliminates a negative pressure in the pump room to prevent the lubricating oil from flowing into the pump room in large quantities.

Abstract: After a vane 4 passes an oil supply groove 13 formed in a housing 2 due to rotation of a rotor 3, a branch passage 12a of an oil supply passage formed in a shank 3B of the rotor communicates with the oil supply groove 13, then a lubricating oil flows into a pump room 2A through the oil supply groove 13. Then, owing to a differential pressure between a first space A and a second space B, the lubricating oil which flowed into the first space is spouted in the direction opposite to the rotational direction, being blown against the vane which subsequently passes, thereby sealing a gap between the vane and the pump room can be rapidly carried out.Even if the lubricating oil is not sufficiently fed into the pump room, a vane pump can rapidly exert its original performance.

Abstract: A vane pump comprising a housing, a rotor and a vane is provided. The housing comprises a pump room having an approximately circular inner wall. The rotor rotates at an eccentric position relative to a center of the pump room and slides in contact with a part of the inner wall of the pump room. The vane is rotated by the rotor, for dividing the pump room into a plurality of spaces full-time. In the housing, among spaces divided by a center line drawn between the center of the pump room and a center of rotation of the rotor, an intake passage in one space and an exhaust passage in the other space are formed, respectively. An oil supply passage is formed in the rotor and the housing. A lubricating oil is intermittently fed through a communicating hole of the oil supply passage.
