Abstract
An air compressor includes two housings secured to a base and each having a piston slidably received in the housings. A weight is rotatably secured to the base and includes an eccentric pin rotatably coupled to the piston rods for moving the pistons relative to the housings to conduct the pumping operations. A motor is secured to the base and has a pinion. A gear is rotatably secured to the base with the pivot shaft and engaged with the pinion and driven by the motor via the pinion. The housings may be adjustably secured to the base.
