The invention discloses an oilless scroll automobile braking vacuum booster pump which comprises a base, a static disc, a dynamic disc, a floating isolating ring and an anti-rotation mechanism; an exhaust port is formed in the static disc; the static disc and the dynamic disc are oppositely mounted; the dynamic disc is connected with an eccentric driving device and rotates along with the eccentricdriving device; when the dynamic disc rotates, the dynamic disc swings under the restraining action of the anti-rotation mechanism; the eccentric driving device is mounted on the base; the anti-rotation mechanism is connected with the dynamic disc and the base; the exhaust port is provided with a one-way check valve; the anti-rotation mechanism comprises an upper anti-rotation pad, a low anti-rotation pad and a ball; the upper and lower ends of the ball are mounted in arc shaped limiting grooves of the upper anti-rotation pad and the low anti-rotation pad in a matching manner; and the floating isolating ring is connected with the dynamic disc and the base separately to form an independent motion area between the dynamic disc and the base. The oilless scroll automobile braking vacuum booster pump has the advantages of preventing reverse water absorption, effectively avoids brake failure, and being steady in working, small in friction coefficient and noise and long in service life.
