Air compressor

Abstract

Disclosed is an air compressor including a cylinder including a recessed compression chamber, and an orbiter including a frame forming a main body and a piston rod protruding from the frame, wherein the piston rod includes a piston rod inner circumferential surface and a piston rod outer circumferential surface, the piston rod having an ending part formed at its end to protrude from the frame, a diameter of an imaginary circle derived from the curvature formed on the ending part formed at the end of the piston rod is larger than a width ranging from the piston rod inner circumferential surface to the piston rod outer circumferential surface, the piston rod is shaped of a transformed ring having a non-continuous portion, the piston rod inner circumferential surface is an inner circumferential surface shaped of the transformed ring, the piston rod outer circumferential surface is an outer circumferential surface shaped of the transformed ring, and the ending part is defined by the non-continuous portion of the transformed ring. Therefore, in compressing the external air due to a contact between the closed surface of the terminal portion of the compression chamber and the ending part of the terminal portion of the piston rod, a contact area is increased, thereby increasing the compressive force of the air compressor.
