The invention relates to a novel automotive electric
vacuum pump with two swinging spherical pistons. The electric
vacuum pump comprises a pump body, an
electric motor, an eccentric shaft, the two spherical pistons, two air inlet valves, a silencer and an air
pipe connector, wherein the pump body is of a special-shaped structure, is formed by die-
casting aluminum
alloy and comprises two cylinders, a proper distance is reserved between the two cylinders, and an end cover for sealing the outer end of an inner hole of each cylinder is arranged at one end of the outer side of the corresponding cylinder. A through hole is formed in the pump body, the proper distance is reserved between one end of the inner side of one cylinder and one end of the inner side of the other cylinder, a balancing block is arranged on the eccentric shaft, and a
check valve is arranged on the silencer. The electric
vacuum pump with the two swinging spherical pistons is simple in structure, good in sealing performance and low-temperature performance, low in
noise, small in vibration, long in continuous working time, and capable of meeting environmental requirements and riding comfort requirements when the automobiles are used.
