A linear oscillating pressurizing includes a main body having an air outlet end and an air outlet valve, two electromagnetic elements disposed in the main body, a piston element disposed between the two electromagnetic elements, which has an air inlet valve disposed thereon, and a control circuit to generate oscillating current pulses. By using a series of current pulses generated from the control circuit, one can magnetize the two electromagnetic elements to the same polarity. By changing the polarity of the electromagnetic element, the attractive force and the repulsive force exerted on the piston element doubles the magnetic force used for reciprocating the piston element. By further incorporating the reciprocating movement of the piston element with the air flow, a pressurizing device having a doubled pressurizing output is obtained.
