PURPOSE: A rotary air compressor is provided to minimize vibration in an orbiter which guides a stable eccentric cam motion, and to extend the service life of each component by easily heat-exchanging with external air. CONSTITUTION: A rotary air compressor comprises an eccentric rotary shaft(100), a cylinder(200), an orbiter, multiple driven holders, and a frame(500). The eccentric rotary shaft has a first eccentric part, a second eccentric part, and a balance weight. An eccentric space is formed inside the cylinder. The cylinder has a sealed part which divides a compression chamber from the eccentric space. The orbiter has multiple grooves, a frame, and a piston rod. The driven holders guide the orbiter to have a stable eccentric cam motion. The frame is coupled to the cylinder, and forms multiple air passages(532). |
