Abstract

A rotary blade type vacuum pump comprises a supporting body 2 for a shaft 11 for rotating a rotor 13 fitted with at least three blades 15 equally spaced angularly and slidable inside radial cavities 14 formed in the rotor 13. The outer ends of the blades (15) are maintained contacting the inner surface of a work cavity 10 in the body 2 so as to form variable-volume chambers 48 between the blades 15. The inner ends of the blades 15 simultaneously contact a pair of annular elements 70 housed in respective cavities 71 at either end of the rotor 13 and movable in planes perpendicular to the axis of the rotor 13. Lubrication passages 63, 18, 17 and 16 are provided to supply oil to cavity 71 from which it can seep into work cavity 10 to improve sealing between chambers 48.
