Claims

[Scope of utility model registration request]

A pump casing is disposed below the oil level in the oil reservoir, a vaned rotor that performs a pump function is housed in the pump casing, and one end of the rotating shaft supporting the rotor is attached to one side wall of the pump casing. The centrifugal type pump is a centrifugal type, in which a starting end of an oil supply passage communicating with the inside of the pump casing is opened on the outer circumferential surface of the protruding end of the rotating shaft, and this starting end opening is provided on the rotating shaft. In a vacuum pump configured to be opened and closed by a valve mechanism, a centrifugal separation case that surrounds a starting end opening of the oil supply path and a preparatory mechanism is attached to a protruding end of the rotary shaft so as to be rotatable integrally with the rotary shaft; An oil rotary vacuum pump characterized in that an oil introduction hole is provided in the end wall of the pump, and a contaminant discharge hole is provided in the peripheral wall.
