Zusammenfassung:	The utility model relates to the technical field of pumps, in particular to a novel rotary-vane type vacuum pump preventing oil return. The vacuum pump is characterized by comprising an air intake, a filter screen, an oil baffle sealing ring, an air intake O-shaped sealing ring, a rotary-vane spring, a rotary vane, a rotor, a pump body, an oil tank, No. 1 vacuum pump oil, an air release valve plate, an air intake pipe and an oil baffle. For the vacuum pump, the oil intake pipe is provided with the oil baffle, the oil baffle is provided with the oil baffle sealing ring, and the oil baffle sealing ring is made of flexible rubber. For the novel rotary-vane type vacuum pump preventing oil return, the arrangement of the oil baffle and the oil baffle sealing ring prevents the phenomenon of oil return when the vacuum pump is stopped. Both the gas flow loss and the consumption are reduced.
