The subject innovation is to the inside during relates to a swing-type oil-free compressor (swing type oil free compressor) is mounted is used to supply the air required for pressure-feeding of the powder or the like specially equipped vehicles for powder transport, and more particularly, to an air intake stroke cylinder relates to a swing-type oil-free compressor designed to increase the pressure and amount of air to be discharged by increasing the amount of intake air, and that the pressure of compressed air. Swing-type oil-free compressor according to the present invention, the substrate for opening and closing of the drive unit where the power transmission mechanism to the crankshaft through the connecting rod reciprocates to rotate the rotor as the rotating internal suction port, the suction hole and the suction holes of the inlet valve it is that the rotor and the intake valve base is built in form compression of air through the suction stroke and the discharge hole, the discharge port, the discharge pipe of air through the tube, a suction port, a suction hole, as the rotor rotates wanbok movement - the discharge stroke in the swing-type oil-free compressor, including at the same time the cylinder portion made of, is coupled to the cylinder portion suction tube in the housing upper part of the driving unit including a blower fan for periodic supply of at least atmospheric air on the outside of the plate-like suction valve and that is characterized.
