摘要

The air compressor includes a gear (14) engaged on a weight (15) and rotated in cooperation with the weight relative with a base (1) about the pivot axle (152) of the weight. A motor (5) is fixed to the base and having a pinion (51) engaged with the gear for rotating the gear and weight, and for moving a piston rod (21) relative to the cylinder in a reciprocating action. A bearing (12) is engaged in the aperture of the base. The weight has a pivot axle extended outward and engaged in bearing, and rotatably secured to a casing with the bearing. A shaft is extended from the weight and eccentric relative to the pivot axle.
