The invention discloses an improved vacuum pump for an automobile. The improved vacuum pump comprises a pump body, wherein the pump body is internally provided with a rotor, four blade grooves are formed in the rotor, the four blade grooves are distributed on the four sides of the rotor, and the two opposite blade grooves are parallel; the two adjacent two blade grooves are vertical, the four blade grooves are internally provided with blades, and the outer ring of the rotor is divided into four parts by virtue of the four blade grooves; each part of the rotor is internally provided with a cavity, the cavities are internally provided with balance blocks, and the pump body is provided with an air exhaust hole, an air outlet and a driving shaft; the air exhaust hole is provided with a check valve, the driving shaft is fixedly provided with a belt pulley, the belt pulley is connected with an engine by virtue of a belt, and the pump body is fixedly provided with a cover plate. The rotor of the vacuum pump for the automobile is provided with four blade grooves, the four blade grooves are distributed on the four sides of the rotor, the two opposite blade grooves are parallel, and the two adjacent blade grooves are vertical, so that the length of the blade grooves is relatively great as much as possible, therefore, when the rotor rotates, the volume swept by the blades is relatively big, and the efficiency is relatively high.
