PURPOSE: A compressor having multiple cylinders is provided to reduce gas loss caused by the pressure pulsation of the inhaled and exhausted gas. CONSTITUTION: A compressor having multiple cylinders comprises a crank shaft(210), a piston(230), and a connecting rod(220). The crank shaft is rotated by receiving power from an electric motor. The piston shaft is arranged at a right angle to the center shaft of the crank shaft and is reciprocated in each cylinder(A,B,C,D) having an intake valve and an exhaust valve. One end of the connecting rod is coupled to a crank arm of the crank shaft through a pin, and the other end is coupled to the piston through a pin.
