Abstract
PURPOSE: To decrease noises, by fitting an oil seal in an oil pocket in an oil supply device for an oil-revolved vacuum pump to reduce the vibration sound of vanes and the opening and closing sound of a discharge valve.
CONSTITUTION: When a rotor 6 is driven by a motor 2, air sucked through a suction port 15 is compressed and discharged through a discharge valve 10. At the same time, oil sucked through an oil supply hole 16 by pumping action in an oil pocket 14 is supplied to a rotor bearing 17 and a cylinder chamber 8. Since the oil supply to the cylinder chamber 8 is restricted by the clearance between the inside surface of the lip 20 of an oil seal 18 and the outside surface of a rotor shaft 7, the axial vibration of vanes 9 and the impact of the oil on a release valve 10 are reduced.
