<p>An air compressor of weight-reduction type is disclosed, wherein the bearing (29) and the main housing (1) thereof are formed integrally, so that when the piston body (25) conducts reciprocating motion within the cylinder (3) at high frequencies, the bearing (29) is firmly fixed on the main housing (1) without nonfunctioning or falling off. Furthermore, the main housing (1) and the cylinder (3) thereof are made of plastic and formed integrally. The main housing (1) is formed with a wind collecting hood (15) to facilitate the air flow being introduced through the main housing (1) for rapidly dissipating the heat generated by the bearing (29) and the heat generated from the reciprocating motion of the piston body (25). Accordingly, the manufacturing cost of the air compressor can be reduced to achieve an economical design, and the weight of the air compressor can be reduced to facilitate the compressor being carried onto a vehicle.</p> |
